CSA Preface<\/strong><\/p>\n

<\/p>\n

This is the fourth edition of CSA C22.2 No. 60079-0, Explosive atmospheres \u2014 Part 0: Equipment \u2014 General requirements, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60079-0 (seventh edition, 2017-12). It supersedes the previous edition published in 2015 as CAN\/CSA-C22.2 No. 60079-0 (adopted IEC 60079-0:2011). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code.<\/span><\/p>\n

<\/p>\n

For brevity, this Standard will be referred to as CSA C22.2 No. 60079-0 throughout.<\/span><\/p>\n

<\/p>\n

Changes to this edition include<\/span><\/p>\n

<\/p>\n

a) clarification of the definition of certificate as it applies in Canada;<\/span><\/p>\n

<\/p>\n

b) removal of the deviations for the definitions of dust and dust equipment grouping, which are now aligned with IEC;<\/span><\/p>\n

<\/p>\n

c) updates to the deviations for bonding as a result of the changes in IEC 60079-0:2017 and to align with the Canadian Electrical Code, Part I;<\/span><\/p>\n

<\/p>\n

d) clarification of the thermal test for dust enclosures; and<\/span><\/p>\n

<\/p>\n

e) clarification of the dust marking requirement.<\/span><\/p>\n

<\/p>\n

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.<\/span><\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

This part of IEC 60079 specifies the general requirements for construction, testing and marking of Ex Equipment and Ex Components intended for use in explosive atmospheres.<\/span><\/p>\n

<\/p>\n

The standard atmospheric conditions (relating to the explosion<\/span><\/p>\n

characteristics of the atmosphere) under which it may be assumed that Ex Equipment can be operated are:<\/span><\/p>\n

<\/p>\n

\u2022 temperature \u201320 \u00b0C to +60 \u00b0C;<\/span><\/p>\n

<\/p>\n

\u2022 pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and<\/span><\/p>\n

<\/p>\n

\u2022 air with normal oxygen content, typically 21 % v\/v.<\/span><\/p>\n

<\/p>\n

This part of IEC 60079 and other standards supplementing this standard specify additional test requirements for Ex Equipment operating outside the standard temperature range, but further additional consideration and additional testing may be required for Ex Equipment operating outside the standard atmospheric pressure range and standard oxygen content. Such additional testing may be particularly relevant with respect to Types of Protection that depend on quenching of a flame such as \u2018flameproof enclosures d\u2019 (IEC 60079-1) or limitation of energy, \u2018intrinsic safety i\u2019 (IEC 60079-11).<\/span><\/p>\n

<\/p>\n

NOTE 1 Although the standard atmospheric conditions above give a temperature range for the atmosphere of -20 \u00b0C to +60 \u00b0C, the normal ambient temperature range for the Ex Equipment is \u201320 \u00b0C to +40 \u00b0C, unless otherwise specified and marked. See 5.1.1. It is considered that \u201320 \u00b0C to +40 \u00b0C is appropriate for many items of Ex Equipment and that to manufacture all Ex Equipment to be suitable for a standard atmosphere upper ambient temperature of +60 \u00b0C would place unnecessary design constraints.<\/span><\/p>\n

<\/p>\n

NOTE 2 Requirements given in this standard result from an ignition hazard assessment made on equipment. The ignition sources taken into account are those found associated with this type of equipment, such as hot surfaces, electromagnetic radiation, mechanically generated sparks, mechanical impacts resulting in thermite reactions, electrical arcing and static electric discharge in normal industrial environments.<\/span><\/p>\n

<\/p>\n

NOTE 3 Where an explosive gas atmosphere and a combustible dust atmosphere are, or can be, present at the same time, the simultaneous presence of both often warrants additional protective measures. Additional guidance on the use of Ex Equipment in hybrid mixtures (mixture of a flammable gas or vapour with a combustible dust or combustible flyings) is given in IEC 60079-14.<\/span><\/p>\n

<\/p>\n

IEC 60079 does not specify requirements for safety, other than those directly related to the explosion risk.<\/span><\/p>\n

<\/p>\n

Ignition sources like adiabatic compression, shock waves, exothermic chemical reaction, self-ignition of dust, naked flames and hot gases\/liquids, are not addressed by this standard.<\/span><\/p>\n

<\/p>\n

NOTE 4 Although outside the scope of this standard, such equipment would typically be subjected to a hazard analysis that identifies and lists all of the potential sources of ignition by the equipment and the measures to be applied to prevent them becoming effective. See ISO\/IEC 80079-36.<\/span><\/p>\n
