1 Scope 
This part of IEC 61400 deals with safety philosophy, quality assurance, and engineering  integrity and specifies requirements for the safety of small wind turbines (SWTs) including design, installation, maintenance and operation under specified external conditions. Its purpose is to provide the appropriate level of protection against damage from hazards from these systems during their planned lifetime. 

This standard is concerned with all subsystems of SWTs such as protection mechanisms, internal electrical systems, mechanical systems, support structures, foundations and the electrical interconnection with the load. A small wind turbine system includes the wind turbine itself including support structures, the turbine controller, the charge controller / inverter (if required), wiring and disconnects, the installation and operation manual(s) and other documentation. 

While this standard is similar to IEC 61400-1, it does simplify and make significant changes in order to be applicable to small wind turbines. Any of the requirements of this standard may be altered if it can be suitably demonstrated that the safety of the turbine system is not compromised. This provision, however, does not apply to the classification and the associated definitions of external conditions in Clause 6. Compliance with this standard does not relieve any person, organisation, or corporation from the responsibility of observing other applicable regulations. 

This standard applies to wind turbines with a rotor swept area smaller than or equal to 200 m2, generating electricity at a voltage below 1 000 V a.c. or 1 500 V d.c. for both on-grid and off-grid applications. This standard should be used together with the appropriate IEC and ISO standards (see Clause 2). 

Scope:

This performance Standard includes requirements for:

(a) the determination of physical properties;

(b) non-reinforced circular concrete pipe and accessories;

(c) reinforced circular concrete pipe and accessories;

(d) circular precast concrete pipe, manhole (maintenance hole) sections and accessories; and

(d) precast reinforced circular concrete manhole (maintenance hole) sections, including base sections, riser sections, catch basins, and appurtenances such as grade rings, tops, and special sections.

1 Scope 

1.1

This Code applies to

a) the storage, handling, and transfer of propane;

b) propane used as an engine fuel in other than motor vehicles; and

c) the installation, operation, and maintenance of and to be used for propane at customer locations, in distribution locations and 

1.2

This Code does not apply to

(a) transportation of propane;

(b) manufacture, selection, and use of standardized means of containment under the Transportation of Dangerous Goods Act and Regulations;

(d) marine or pipeline terminals;

(e) gas where used as a feedstock in petroleum refineries or chemical plants;

(f) utility pipeline distribution and transmission pipelines;

(g) refrigerated storage or underground formations for propane;

(h) propane used on boats;

(i) propane used as a propellant in aerosol ;

(j) butane fuel of 6.2 oz (175 g) capacity or less;

(k) any equipment extending downstream from the inlet to any container pressure regulator (commonly referred to as first-stage regulator); propane fuel system components and tanks on vehicles covered by CSA B149.5; and

(m) propane used as refrigerant. 

1.3

Where the term “propane” is used, the requirements of this Code include, and apply equally to, any material that is composed predominantly of any of the following hydrocarbons or mixtures of them: propane, propylene, butanes (normal butane or isobutane), and butylenes.

1.4

The values given in yard/pound units are the standard, unless noted otherwise. This Code contains SI (metric) equivalents to yard/pound units so that the Code can be used in SI (metric) units. SI (metric) equivalents may be approximate unless they are the standard. 

1.5

In this Code, unless approved otherwise by the authority having jurisdiction, “shall” indicates a mandatory requirement; “should” indicates a recommendation or that which is advised but not mandatory; and “may” indicates an advisory or optional statement. Notes to the text do not include mandatory or alternative requirements. The purpose of a note is to separate from the text explanatory or informative material that is not properly a part of this Code. Notes to figures and tables, however, are considered part of the figure or table and may be written as mandatory requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 

1.6

This Code and any standards referenced in it do not make or imply any assurance or guarantee with respect to the life expectancy, durability, or operating performance of equipment and materials referenced in the Code.

1 Scope

1.1

This Standard applies to a complete cablebus system (termination to termination) and associated fittings rated at not more than 46 kV ac or dc, and intended for use in accordance with the National Electrical Code (NEC), the Canadian Electrical Code, Part I and General Requirements — Canadian Electrical Code, Part II, CSA C22.2 No. 0. These requirements do not apply to metal enclosed busways, as covered by CSA C22.2 No. 201 and CSA C22.2 No. 27 / UL 857.

1.2

For the purpose of these requirements, a cablebus is an assembly of  single conductors and/or cables designed as a system to transmit large magnitudes of electrical current and to withstand the effects of specified system requirements (i.e. short-circuit current, circuit loading, bonding etc) with fittings and conductor terminations in a completely enclosed, ventilated, or non-ventilated protective metal housing.

1.3

This standard also applies to transition enclosures used for the transition between cablebus and adjoining equipment, where applicable.

1.4

Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information.

1.5

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

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.

This International Standard applies to controllers intended for starting, controlling and stopping stationary fire pumps, including automatic and non-automatic types for  alternating current electric motor or diesel engine-driven fire pumps. It is anticipated that  a controller only controls a single driver. 

Controllers for electric motor-driven fire pumps always include suitable short-circuit  protection as an integral part of the controller. These controllers may include an integral  power transfer switch. These controllers are rated 1 000 V a.c. maximum. 

Controllers for diesel engine-driven fire pumps include electrical circuits that operate  various control and supervisory functions, such as remote control (starting), alarms,  signals, indicators, and the proper operation of battery chargers. 

The most significant purpose of this standard is to characterize the unique features of fire pump controllers. A further purpose is to prescribe a procedure for exercising the controllers to verify that the unique features are operative. For the purpose of this standard, this procedure is described as the “fire pump controller test protocol”. 

Scope

This part of IEC 62133 specifies requirements and tests for the safe operation of portable sealed secondary nickel cells and batteries containing alkaline electrolyte, under intended use and reasonably foreseeable misuse.

1DV.1 D1 Modification to add the following paragraph and note to Clause 1:

This standard is not, by itself, generally suitable for the evaluation of the safety of end-products, as it lacks specific requirements regarding charging, the effect of normal loads, abnormal conditions that should be considered and the physical and electromagnetic stresses encountered in the anticipated environment of the end-product.

NOTE Battery packs with additional features or circuitry, including integral circuitry that facilitates charging, are considered to be end-products.

1DV.2 DR Modification to add the following paragraph to Clause 1 (Canada only):

This standard deals with the covered components used in accordance with CAN/CSA-C22.2 No. 0.
