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

<\/p>\n

This is the fourth edition of CSA C22.2 No. 30, Explosion-proof equipment<\/em>. It supersedes previous editions published in 1986, 1984, and 1970. It is one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code.<\/p>\n

<\/p>\n

This edition includes requirements for sealing fittings to retain the sealing compound, requirements for the sealing compounds, and requirements for enclosures that involve explosive fluids.<\/p>\n

<\/p>\n

For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN\/CSA-C22.2 No. 0, General requirements \u2014 Canadian Electrical Code, Part II.<\/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.<\/p>\n

<\/p>\n

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

<\/p>\n

1.1<\/p>\n

This Standard applies to explosion-proof electrical equipment suitable for use in hazardous locations in accordance with CSA C22.1, Canadian Electrical Code, Part I and the requirements of CSA M421. It applies to explosion-proof enclosures, parts of enclosures and other related equipment constructed of metallic and non-metallic materials.<\/p>\n

<\/p>\n

1.2<\/p>\n

Other Standards for hazardous location equipment covering specific types of equipment take precedence over this Standard.<\/p>\n

<\/p>\n

1.3<\/p>\n

The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it may be assumed that equipment can be operated are<\/p>\n

<\/p>\n

a) temperature \u201350 \u00b0C to +60 \u00b0C;<\/p>\n

<\/p>\n

b) pressure 80 kPa to 110 kPa; and<\/p>\n

<\/p>\n

c) air with normal oxygen content, typically 21% by volume.<\/p>\n

<\/p>\n

Note: Although the standard atmospheric conditions above give a temperature range for the atmosphere of \u201350 \u00b0C to +60 \u00b0C, the normal ambient temperature range for the equipment is \u201350 \u00b0C to +40 \u00b0C, unless otherwise specified and marked.<\/p>\n

<\/p>\n

1.4<\/p>\n

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.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n","protected":false},"excerpt":{"rendered":"
