• to a separate HIGH-TEMPERATURE OPERATION (HTO) DETECTOR.

• to a BURNER CONTROL SYSTEM intended to be used in warm air heating appliances (furnaces) where the appliance is equipped with an electromechanical differential pressure control to monitor the difference of the combustion air pressure (Type 2.AL). This pressure control provides a switch as an alternative to one of the two switching elements to directly de-energize the safety relevant terminals.

NOTE 1 Throughout this document, where it can be used unambiguously, the word system means burner control system and systems means burner control systems.

NOTE 2 Throughout this document, the word equipment means appliance and equipment.

This standard does not apply to thermoelectric flame supervision controls; thermoelectric flame supervision controls are covered by ISO 23551-6.

This document also applies to electrical BURNER CONTROL SYSTEMS intended exclusively for industrial process applications e.g. those applications covered by ISO TC 244 (ISO 13577).

This document applies to controls powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V.

Components of burner control systems such as electrodes, flame supervision, oxygen depletion safety shut-off systems (ODS), thermoelectric safety shut-off devices, pilot burners, thermocouples, fast-acting thermocouples, and other components are covered by this Part 2-5. (Refer to Annex DVKK.)

1.1DV.2 D2 Modification of 1.1 of the Part 2 by adding the following note:

NOTE 3DV Requirements for separate ignition transformers are covered in UL 506 and CSA C22.2 No. 13.

1.1DV.3 DE Modification of 1.1 of the Part 2 by adding the following:

In Canada, this Standard applies to equipment that is intended to be installed or used in accordance with CSA C22.1, Canadian Electrical Code, Part I. In Canada, general requirements applicable to these products are provided in CSA C22.2 No. 0.

1.1.1 This document applies to the inherent safety, to the declared OPERATING VALUES, OPERATING TIMES and OPERATING SEQUENCES where such are associated with burner safety and to the testing of automatic electrical BURNER CONTROL SYSTEMS used in, on, or in association with, burners.

NOTE Requirements for specific OPERATING VALUES, OPERATING TIMES and OPERATING SEQUENCES are given in the standards for appliances and equipment.

1.1.2 This document applies to AC or DC powered systems with a rated voltage not exceeding 660 V AC or 600 V DC.

1.1.3 This document does not take into account the RESPONSE VALUE of an AUTOMATIC ACTION of a CONTROL, if such a RESPONSE VALUE is dependent upon the method of mounting the control in the equipment. Where a RESPONSE VALUE is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer applies.

1.1.4 This document applies also to systems incorporating ELECTRONIC DEVICES, requirements for which are contained in Annex H.

1.1.4DV D2 Modification of 1.1.4 of the Part 2 by adding the following:

This Standard also applies to manufacturing and production testing (see Annex DVLL) and solid-state oil igniters (see Annex DVMM).

1.1.5 This document applies to systems using NTC or PTC thermistors, additional requirements for which are contained in Annex J.

1.1.8 This document does not address the integrity of the output signal to the network devices, such as interoperability with other devices, unless it has been evaluated as part of the control system.

1.1 This Standard specifies the requirements for insulating tubing that is usually round in cross-section and that consists entirely of extruded compounds whose characteristic constituents are thermosetting, elastomeric, or thermoplastic polymers (see Table 1 for materials and ratings). These requirements also cover heat-shrinkable and crosslinked tubing.

1.2. Tubing is intended for use only in air – in dry and damp locations – as part of the internal wiring of electrical devices and appliances in accordance with the Canadian Electrical Code, Part I  (CE Code, Part 1 I) and ANSI/NFPA 70, National Electrical Code (NEC). It may be used for insulating one or more inadequately insulated conductors, bus bars, motor leads, transformer leads, terminal lugs, or small assemblies of electronic components. Tubing is not intended for use in contact with sharp edges, corners, or projections, or where subject to tension, compression, or repeated flexing. Tubing is not intended for use where it is feasible to employ a standard insulated conductor (appliance-wiring material) intended specifically for the purpose.

1.3 These requirements do not apply to fabric tubing, chemically dilated tubing, polymeric tubing extruded with reinforcement, or tubing intended only for mechanical protection.

1.4 The acceptability of tubing in any particular device or appliance depends upon its acceptability for continued use under the conditions that prevail in actual service. Accordingly, for a particular application, it will in some cases be necessary to employ tubing having features other than or in addition to those specified in these requirements. For example, tubing may be required to have a heavier wall thickness or a flat rather than a round cross-section; it may be required to have inherent resistance to the effects of immersion in water, oil, solvents, or other liquids (or their vapors); it may be required to be used in an environment conducive to the development of fungi and similar organisms.

Appliances not intended for normal household use, but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

As far as is practicable, this standard deals with the common hazards presented by appliances, which are encountered by all persons in and around the home. However, in general, it does not take into account

– persons (including children) whose

• physical, sensory or mental capabilities; or

• lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;

– children playing with the appliance.

Attention is drawn to the fact that

– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;

– in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national authorities responsible for the safety of pressure vessels. and similar authorities.

This standard does not apply to

– ironers (IEC 60335-2-44);

– ironing boards;

– appliances designed exclusively for industrial purposes;

– appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).

1.1 This Part is intended to be read together with the Standard for Low-Voltage Fuses – Part 1: General Requirements, hereafter referred to as Part 1. The titles of the Clauses in this Part correspond to the similarly titled Clauses in Part 1. The requirements of Part 1 apply unless modified by this Part. For the Part 1 requirements, refer to the Standard for Low-Voltage Fuses – Part 1: General Requirements, NMX-J-009-248/1-ANCE / CSA C22.2 No. 248.1 / UL 248-1.

1.2 This Part applies to Class K fuses rated 600 A or less and either 250 or 600 V ac. DC ratings are optional.

1.1 This Part is intended to be read together with the Standard for Low-Voltage Fuses – Part 1: General Requirements, hereafter referred to as Part 1. The titles of the Clauses in this Part correspond to the similarly titled Clauses in Part 1. The requirements of Part 1 apply unless modified by this Part. For the Part 1 requirements, refer to the Standard for Low-Voltage Fuses – Part 1: General Requirements, NMX-J-009-248/1-ANCE / CSA C22.2 No. 248.1 / UL 248-1.

1.2 This Part applies to supplemental fuses rated 60 A or less intended only for supplementary overcurrent protection where branch circuit or equivalent applications are not involved. DC ratings are optional.

This standard applies to a.c. semiconductor motor controllers and starters, which may include a series mechanical switching device, intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c.

This standard characterizes a.c. semiconductor motor controllers and starters with and without bypass means.

AC semiconductor motor controllers and starters dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 8.2.4) should form part of the installation, but not necessarily of the a.c. semiconductor motor controller or starter.

In this context, this standard gives requirements for a.c. semiconductor motor controllers and starters associated with separate short-circuit protective devices.

This standard does not apply to

– continuous operation of a.c. motors at motor speeds other than the normal speed;

– semiconductor equipment, including semiconductor contactors (see 2.2.13 of IEC 60947-1:2007) controlling non-motor loads;

– electronic a.c. power controllers covered by IEC 60146 series.

Contactors, overload relays and control circuit devices used in a.c. semiconductor motor controllers and starters should comply with the requirements of their relevant product standard. Where mechanical switching devices are used, they should meet the requirements of their own IEC product standard, and the additional requirements of this standard.

The object of this standard is to state as follows:

– the characteristics of a.c. semiconductor motor controllers and starters and associated equipment;

– the conditions with which a.c. semiconductor motor controllers and starters comply with reference to

a) their operation and behaviour;

b) their dielectric properties;

c) the degrees of protection provided by their enclosures where applicable;

d) their construction;

– the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests;

– the information to be given with the equipment, or in the manufacturer's literature.

NOTE For the purpose of this standard, the term "controller" may be used instead of "a.c. semiconductor motor controller".

1DV D2 Modification of Clause 1 by adding the following:

1DV.1 This equipment is intended for installation in accordance with CSA C22.1, Canadian Electrical Code (CE Code, Part I), and the US National Electrical Code (NEC), NFPA 70.

1DV.2 This standard also applies to combination motor controllers incorporating semiconductor motor controllers and starters. See Annex DVC for specific requirements.

1.1 Scope

This part of IEC 60947 applies to the types of equipment listed in 1.1.1 and 1.1.2 whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.

Starters and/or contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 9.3.4) forms part of the installation but not necessarily of the contactor or the starter.

In this context, this standard gives requirements for:

– contactors associated with overload and/or short-circuit protective devices;

– starters associated with separate short-circuit protective devices and/or with separate short-circuit and integrated overload protective devices;

– contactors or starters combined, under specified conditions, with their own short-circuit protective devices. Such combinations, e.g. combination starters or protected starters are rated as units.

For circuit-breakers and fuse-combination units used as short-circuit protective devices in combination starters and in protected starters, the requirements of IEC 60947-2 and IEC 60947-3 respectively apply.

Equipment covered by this standard is as follows.

1.1DV.1 D2 Modification of 1.1 by adding the following:

This equipment is intended for installation in accordance with CSA C22.1, Canadian Electrical Code (CE Code, Part I), and the US National Electrical Code (NEC), NFPA 70.

1.1.1 AC and DC contactors

AC and DC contactors intended for closing and opening electric circuits and, if combined with suitable relays (see 1.1.2), for protecting these circuits against operating overloads which may occur therein.

NOTE For contactors combined with suitable relays and which are intended to provide short-circuit protection, the relevant conditions specified for circuit-breakers (IEC 60947-2) additionally apply.

This standard applies also to the actuators of contactor relays and to the contacts dedicated exclusively to the coil circuit of a contactor.

Contactors or starters with an electronically controlled electromagnet are also covered by this standard.

1.1.1DV.1 D2 Modification of 1.1.1 by adding the following:

This standard also applies to manual controllers and combination motor controllers. See Annex DVC for specific requirements.

1.1.2 AC motor-starters

AC motor-starters (including motor management starter) intended to start and accelerate motors to normal speed, to ensure continuous operation of motors, to switch off the supply from the motor and to provide means for the protection of motors and associated circuits against operating overloads.

For overload relays for starters, including those based on electronic technology with or without extended functions according to Annex H, the requirements of this standard apply.

1.1.2.1 Direct-on-line (full voltage) a.c. starters

Direct-on-line starters intended to start and accelerate a motor to normal speed, to provide means for the protection of the motor and its associated circuits against operating overloads, and to switch off the supply from the motor.

This standard applies also to reversing starters.

1.1.2.2 Reduced voltage a.c. starters

Reduced voltage a.c. starters intended to start and accelerate a motor to normal speed by connecting the line voltage across the motor terminals in more than one step or by gradually increasing the voltage applied to the terminals, to provide means for the protection of the motor and its associated circuits against operating overloads, and to switch off the supply from the motor.

Automatic change-over devices may be used to control the successive switching operations from one step to the others. Such automatic change-over devices are, for example, time-delay contactor relays or specified time all-or-nothing relays, under-current devices and automatic acceleration control devices (see 5.10).

1.1.2.2.1 Star-delta starters

Star-delta starters intended to start a three-phase motor in the star connection, to ensure continuous operation in the delta connection, to provide means for the protection of the motor and its associated circuits against operating overloads, and to switch off the supply from the motor.

The star-delta starters dealt with in this standard are not intended for reversing motors rapidly and, therefore, utilization category AC-4 does not apply.

NOTE In the star connection, the starting current in the line and the torque of the motor are about one-third of the corresponding values for delta connection. Therefore, star-delta starters are used when the inrush current due to the starting is to be limited, or when the driven machine requires a limited torque for starting. Figure 1 indicates typical curves of starting current, of starting torque of the motor and of torque of the driven machine.

1.1.2.2.2 Two-step auto-transformer starters

Two-step auto-transformer starters, intended to start and accelerate an a.c. induction motor from rest with reduced torque to normal speed and to provide means for the protection of the motor and its associated circuits against operating overloads, and to switch off the supply from the motor.

This standard applies to auto-transformers which are part of the starter or which constitute a unit specially designed to be associated with the starter.

Auto-transformer starters with more than two steps are not covered by this standard.

The auto-transformer starters dealt with in this standard are not intended for inching duty or reversing motors rapidly and, therefore, utilization category AC-4 does not apply.

NOTE In the starting position, the current in the line and the torque of the motor related to the motor starting with rated voltage are reduced approximately as the square of the ratio (starting voltage):(rated voltage). Therefore, auto-transformer starters are used when the inrush current due to the starting is to be limited or when the driven machine requires a limited torque for starting. Figure 2 indicates typical curves of starting current, of starting torque of the motor and of torque of the driven machine.

1.1.2.3 Rheostatic rotor starters

Starters intended to start an a.c. induction motor having a wound rotor by cutting out resistors previously inserted in the rotor circuit, to provide means for the protection of the motor against operating overloads and to switch off the supply from the motor.

This standard applies also to starters for two directions of rotation when reversal of connections is made with the motor stopped (see 5.3.5.5). Operations including inching and plugging necessitate additional requirements and are subject to agreement between manufacturer and user.

This standard applies to resistors which are part of the starter or constitute a unit specially designed to be associated with the starter.

1.2 Exclusions

This standard does not apply to:

– d.c. starters;

– star-delta starters, rheostatic rotor starters, two-step auto-transformer starters intended for special applications and designed for continuous operation in the starting position;

– unbalanced rheostatic rotor starters, i.e. where the resistances do not have the same value in all phases;

– equipment designed not only for starting, but also for adjustment of speed;

– liquid starters and those of the "liquid-vapour" type;

– semiconductor contactors and starters making use of semiconductor contactors in the main circuit;

– rheostatic stator starters;

– contactors or starters designed for special applications;

– auxiliary contacts of contactors and contacts of contactor relays. These are dealt with in IEC 60947-5-1.

1.3 Object

The object of this standard is to state:

a) the characteristics of contactors and starters and associated equipment;

b) the conditions applicable to contactors and starters with reference to:

1) their operation and behaviour,

2) their dielectric properties,

3) the degrees of protection provided by their enclosures, where applicable,

4) their construction;

c) the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests;

d) the information to be given with the equipment or in the manufacturer's literature.

1.1 Inclusions

This Standard provides requirements for the design and qualification of components for the monitoring and display of NPPs and NPP facility irradiated fuel storage safety functions in the event of a design basis accident (DBA) or a design extension condition (DEC) during the operational phase of the facility lifecycle.

Notes:

This Standard applies only to the functions of plant systems, including safety systems and process control systems, associated with monitoring in the event of an accident; other monitoring functions are beyond the scope of this Standard.

The requirements for a DBA and those for a DEC might differ. Where requirements differ for a DBA and a DEC, the difference is explicitly stated.

General requirements and guidance regarding DECs [as a subset of beyond design basis accidents (BDBAs)] are covered in CSA N290.16.

The operational phase of the facility lifecycle would include the period of time wherein the reactor is capable of operations, generally from the end of commissioning with fuel loaded, through to the end of operations with fuel unloaded prior to decommissioning.

1.2 New and existing NPPs

This Standard applies to existing NPPs and new NPPs.

Notes:

The requirements for new plants and existing plants might differ. Where requirements differ for new plants and existing plants, the difference is explicitly stated.

For existing NPPs, the application should address the information in this Standard to the extent practicable. Any alternative approaches selected or mitigating measures applied should be identified.

This Standard may provide guidance for nuclear facilities other than NPPs, using a graded approach.

1.3 Application

This Standard applies to components and systems that enable NPP staff, in the event of an accident, to

monitor and display the plant safety functions for diagnosing that an accident, including severe accident, is occurring or has occurred;

Note: The purpose of monitoring the plant safety functions is to guide operator actions that might be required as a part of the accident response.

monitor and display plant conditions for the purposes of accident management to continuously address the state of safety functions; and

Note: Accident management refers to specific actions taken within the NPP during the evolution of an accident to prevent escalation, mitigate consequences, and to achieve a long-term controlled stable state. Accident management actions are the responsibility of the plant operator. Refer to CNSC REGDOC-2.3.2 for further clarification.

monitor and display parameters for the initiation of on-site and off-site emergency management to confirm the effectiveness of the accident management actions.

Notes:

Emergency management in this context refers to the overall coordinated response to, mitigation of, and recovery from a nuclear emergency. Emergency management is not concerned with the specific actions taken within the NPP to manage the accident (i.e., accident management as described above). Emergency management actions can be the responsibility of the operating organization or other jurisdictions
(e.g., operator emergency response organizations, government bodies, emergency workers). Refer to CSA N1600 for guidance on nuclear emergency categorization and notification.

If the emergency planning basis, as defined in CSA N1600, does not require off-site emergency management actions, any functions associated with monitoring off-site parameters may be excluded where justified.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.1 Inclusions

Cette norme énonce les exigences relatives à la conception et à la qualification des composants pour la surveillance et l’affichage des fonctions de sûreté des centrales nucléaires et des installations de stockage du combustible irradié dans le cas d’un accident de dimensionnement (AD) ou d’une condition additionnelle de dimensionnement (CAD) pendant la phase d’exploitation du cycle de vie de l’installation.

Notes :

Cette norme s’applique uniquement aux fonctions des systèmes de la centrale, y compris les systèmes de sûreté et les systèmes de commande des procédés, associées à la surveillance en cas d’accident; les autres fonctions de surveillance ne font pas partie du domaine d’application de cette norme.

Il peut y avoir des différences entre les exigences pour un AD et celles pour une CAD. De telles différences, lorsqu’elles existent, sont explicitement mentionnées.

Les exigences et les lignes directrices relatives aux CAD (un sous-ensemble des accidents de dimensionnement [AD]) sont traitées dans CSA N290.16.

La phase d’exploitation du cycle de vie de l’installation comprendrait la période pendant laquelle le réacteur est capable de fonctionner, généralement de la fin de la mise en service lorsque le combustible est chargé à la fin de l’exploitation lorsque le combustible est déchargé avant le déclassement.

1.2  Centrales existantes et nouvelles centrales

Cette norme s’applique aux centrales existantes et aux nouvelles centrales.

Notes :

Les exigences peuvent différer pour les nouvelles centrales et pour les centrales existantes. De telles différences, lorsqu’elles existent, sont explicitement mentionnées.

Dans le cas des centrales existantes, la demande devrait, dans la mesure du possible, porter sur les informations contenues dans la présente norme. Toute autre approche sélectionnée ou mesure d’atténuation appliquée devrait être indiquée.

Cette norme peut orienter les installations nucléaires autres que les centrales nucléaires, selon une méthode graduelle.

1.3 

ApplicabilitéCette norme s’applique aux composants et aux systèmes qui, en cas d’accident, permettent au personnel de la centrale nucléaire de :

a) surveiller et afficher les fonctions de sûreté de la centrale pour diagnostiquer qu’un accident, y compris un accident grave, se produit ou s’est produit;

Note : La surveillance des fonctions de sûreté de la centrale a pour but de guider l’opérateur dans le choix des mesures d’intervention requises à la suite de l’accident.

b) surveiller et afficher l’état de la centrale aux fins de gestion des accidents pour traiter en continu l’état des fonctions de sûreté; et

Note : La gestion des accidents fait référence aux mesures particulières prises dans une centrale nucléaire pendant l’évolution d’un accident de manière à en empêcher l’intensification, atténuer les conséquences et atteindre un état stable contrôlé à long terme. La responsabilité des mesures de gestion des accidents incombe à l’exploitant. Voir le document REGDOC-2.3.2 de la CCSN pour plus de précisions à ce sujet.

c) surveiller et afficher les paramètres pour le déclenchement des mesures de gestion des urgences sur le site et hors site pour confirmer l’efficacité des mesures de gestion des accidents.

Notes :

Dans ce contexte, la gestion des urgences fait référence à l’intervention globale coordonnée pour atténuer une urgence nucléaire et reprendre les activités à la suite d’une telle urgence. La gestion des urgences ne porte pas sur les mesures particulières à prendre dans une centrale nucléaire pour gérer les accidents (c.-à-d., pour la gestion des accidents telle que décrite à l’alinéa précédent). Les mesures de gestion des urgences peuvent être la responsabilité de l’exploitant ou d’autres autorités compétentes (p. ex., les organismes de gestion des urgences de l’exploitant, les organismes gouvernementaux, des travailleurs d’urgence). Voir la CSA N1600 pour les lignes directrices sur la catégorisation des urgences nucléaires et les annonces en cas d’urgence nucléaire.

Si le fondement de la planification d’urgence, telle que définie dans CSA N1600, ne nécessite pas de mesures de gestion des urgences hors site, toute fonction associée à la surveillance des paramètres hors site peut être exclue lorsque cela est justifié.

This document specifies methods of measurement of electrical power consumption in nonactive mode(s), as applicable for electrical lighting equipment. This includes electrical lighting equipment incorporating non-illumination components. This document specifies neither performance requirements nor limits on power consumption. This document applies to lighting equipment connected to a supply voltage up to 600V DC or up to 600V AC. This document is intended to be referenced by lighting equipment product standards for the measurement of non-active mode power consumption. Details for the non-active mode power consumption measurement and data presentation are specified in the product standards. NOTE Annex A provides guidance on details specified in product standards.
