Electrical

IEC 62841-1:2014, Clause 1 is applicable, except as follows:
Addition:
This document applies to hand-held spray guns for non-flammable materials.

1.1    

This Standard specifies the requirements for single-phase, pad-mounted distribution transformers with separable insulated high-voltage connectors and intended primarily for operation by electric utilities.

Note: The operation of transformers complying with this Standard by other than an electric utility can be subject to additional requirements by the electrical inspection authority having jurisdiction.

1.2    

This Standard applies to single-phase, pad-mounted, 60 Hz, liquid-filled distribution transformers with separable insulated high-voltage connectors designed for operating on an effectively grounded wye system, rated at 167 kVA  or less, with an insulation class of 18 kV or less, and suitable for mounting outdoors on pads without additional protective enclosures.

1.3    

This Standard includes voltage ratings, kVA  ratings, certain mechanical characteristics, and test procedures. The Standard also includes the following performance characteristics: energy efficiency (in accordance with CAN/CSA-C802.1), temperature rise, loading capabilities, sound level, and radio influence voltage (RIV).

1.4    

This Standard covers equipment intended primarily for operation on effectively grounded underground distribution systems having preferred rated voltages as shown in Table 1 and a secondary distribution voltage of 240/120 V, three-wire.

1.5    

This Standard is intended to allow for interchangeability between pad-mounted units of the same basic physical size but made by different manufacturers, without modifying the cables or the pad. This Standard covers terminal arrangements for a loop-feed system, including certain minimum dimensions and certain specific dimensions, but does not ensure that the cable entrance compartment of one manufacturer’s transformer matches that of another.

1.6  

When this equipment is intended for operation by other than an electric utility, it is the purchaser’s responsibility to ensure that the unit meets the requirements of the appropriate electrical inspection authority.

1.7    

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 part of IEC 60079, which is a technical specification, specifies requirements for the design, construction, assembly, testing, inspection, marking, documenting and assessment of equipment assemblies for use in explosive atmospheres under the responsibility of the manufacturer of the equipment assembly.

The requirements of this document apply to individual items according to the IEC 60079 series or ISO 80079 series that comprise the assembly and that have individual certificates. These individual items are then integrated as part of the equipment assembly. Also included are requirements to address aspects for the assembly which may be beyond the certificates of the individual items forming the assembly.

The scope of this document includes assessment of the additional requirements for assemblies for hazardous areas and does not include requirements for non-hazardous areas. It is assumed that compliance with other electrical or mechanical requirements that are applicable for non-hazardous areas will be verified by either the same or different party in addition to the requirements of this document.

This document does not apply to:

– equipment which is covered, in its entirety, by one or more IEC 60079 and ISO 80079 equipment types of protection;

– pressurized rooms, p, in accordance with IEC 60079-13, artificial ventilation for the protection of analyzer(s) houses in accordance with IEC TR 60079-16, and other standards addressing specific Ex assemblies;

– installation at the end-user site under the scope of IEC 60079-14;

– classification of the hazardous area;

– equipment assemblies for mines susceptible to firedamp (Group I applications);

– inherently explosive situations and dust from explosives or pyrophoric substances (for example explosives manufacturing and processing);

– rooms used for medical purposes;

– electrical installations in areas where the hazard is due to flammable mist.

The specification is only intended to provide validation for the initial supply of an assembly.

NOTE 1 Additional guidance on the requirements for hazards due to hybrid mixtures of dust or flyings and flammable gas or vapour is provided in IEC 60079-14.

Where a requirement of this document conflicts with a requirement of either IEC 60079-0 or ISO 80079-36, the requirement of this document takes precedence.

NOTE 2 For this first edition, the only requirements of this document that take precedence over IEC 60079-0 or ISO 80079-36 are the markings for equipment assemblies.

1.1

This Standard covers the requirements for dead-end/suspension composite insulators used on overhead distribution lines operating at nominal voltages up to and including 75 kV. Dead-end insulators support the line conductor horizontally. Suspension insulators support the line conductor vertically. Both are subjected to tensile and torsional loads.

These composite insulators are intended to operate in a service environment within a temperature range of –50 to 50 °C.

The main objective of this Standard is to define terms, prescribe test methods, and recommend acceptance or failure criteria. Clauses 4 to 8 specify the material, product qualification, construction and test requirements applicable to these insulators. Annexes D, E, and F provide examples of design, type, and sample/routine test reports.

1.2

This Standard deals with composite insulators having a core with metal fittings and a housing and sheds. The core has resin-impregnated glass fibres. The housing and sheds consist of elastomers (e.g., silicone, ethylene propylene). The metal fittings are aluminum, steel, or iron.

1.3

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.

1.General

This Standard provides an Electrical Energy Storage System (EESS) testing protocol for quality assurance and reliability programs. It is intended to be used by code officials, financial institutions and insurers, first responders, developers, independent engineers, manufacturers and other relevant stakeholders in the Energy Storage System industry. It provides best practices for an EESS testing protocol of a representative energy storage system for quality and reliability assurance programs.

2.Intended use

This Standard is intended to be a stand-alone document that does not interact with other safety or performance standards as it is intended to focus on reliability and quality assurance for long-term durability. Market practices as they currently exist might require independent quality assurance and reliability testing and due diligence for energy storage systems.

3.Inclusions

The individual test legs in the protocol of this Standard have been designed to reproduce incidences and failures of a representative energy storage system that has been seen in the field or potentially could be seen in the field. Data generated from testing will reflect the behavior, reliability, and durability of the system and its components during natural or accidental occurrences of conflagration, inundation, convulsion or other related incidences, as well as reflect the harsh environmental conditions during operation. This data is intended to be used as part of an assessment for bankability and insurability of energy storage systems.

4.Exclusions

This Standard does not apply to the following:

a) evaluating or rating the Individual components used in the construction of an EESS; Note: Individual components are evaluated using their own standards.

1DV DR Modification of Clause 1 to replace with the following:

This part of IEC 60079 standard specifies the construction and testing of intrinsically safe apparatus intended for use in explosive atmospheres, and for associated apparatus which is intended for connection to intrinsically safe circuits which enter such atmospheres.

This Type of Protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing ignition of a surrounding explosive atmosphere. This includes electrical equipment which contains circuits that are intrinsically safe only under certain conditions, for example under battery supply with mains supply removed.

This document is also applicable to electrical equipment or parts of electrical equipment located outside the explosive atmosphere or protected by another Type of Protection listed in IEC 60079-0 UL 60079-0 and CSA C22.2 No. 60079-0, where the intrinsic safety of the electrical circuits in the explosive atmosphere may depend upon the design and construction of such electrical equipment or parts of such electrical equipment. The electrical circuits exposed to the explosive atmosphere are assessed for use in such atmospheres by applying this document.

This document applies to sensors connected to intrinsically safe circuits but does not apply to the protection of catalytic elements for Group IIC or Group IIB + H2.

This document does not apply to Ex Equipment cable glands.

The requirements for intrinsically safe systems are provided in IEC 60079-25 UL 60079-25 and CSA C22.2 No. 60079-25.

This document supplements and modifies the general requirements of IEC 60079-0, UL 60079-0 and CSA C22.2 No. 60079-0 except as indicated in Table 1. Where a requirement of this document conflicts with a requirement of IEC 60079-0 UL 60079-0 and CSA C22.2 No. 60079-0, the requirement of this document takes precedence.

Unless otherwise stated, the requirements in this document are applicable to both intrinsically safe apparatus and associated apparatus, and the generic term "apparatus" is used throughout the standard.

As this document applies only to electrical equipment, the term "equipment" used in the standard always means "electrical equipment".

This document applies to apparatus for use under the atmospheric conditions of IEC 60079-0 UL 60079-0 and CSA C22.2 No. 60079-0 with additional requirements for use at extended atmospheric pressures in the range from 60 kPa (0,6 bar), up to 110 kPa (1,1 bar).

Where references are made to other IEC standards, the referenced requirements found in these standards apply as modified by any applicable US National Differences for the standard (see Clause 2).
