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

<\/p>\n

This is the second edition of CSA M424.1, Flameproof non-rail-bound diesel-powered machines for use in gassy underground coal mines<\/em>. This edition supersedes the previous edition published in 1988.<\/p>\n

<\/p>\n

Changes to this edition include the following:<\/p>\n

<\/p>\n

a) The reference fuel used for the tests has been changed to comply with US CFR 40 1065.703.<\/p>\n

<\/p>\n

b) The term diesel particulate matter is used in lieu of the term particulate matter and this term also replaces the term respirable combustible dust concentration in the EQI formula.<\/p>\n

<\/p>\n

c) Emissions toxicity criterion has been updated to reflect current test practices.<\/p>\n

<\/p>\n

d) Dynamometer emissions test has been revised to reflect current testing practices.<\/p>\n

<\/p>\n

e) Assessing ventilation has been revised to replace EQI factor with the dilution ratio.<\/p>\n

<\/p>\n

f) To comply with current administrative requirements, various Clauses throughout the Standard have either been updated or renumbered.<\/p>\n

<\/p>\n

CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of MDEC (Mining Diesel Emissions Council) and Catalytic Exhaust Products Ltd.<\/p>\n

<\/p>\n

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

<\/p>\n

1.1<\/p>\n

This Standard describes the technical requirements and procedures necessary for the design, performance, and testing of new or unused flameproof, non-rail-bound diesel-powered, self-propelled machines for use in gassy underground mines.<\/p>\n

<\/p>\n

Note: The working environment of gassy mines is characterized by the presence of methane gas and combustible dust.<\/p>\n

<\/p>\n

1.2<\/p>\n

This Standard applies to machines of 45 000 kg mass or less, which are designed to operate on level ground at a maximum speed of 32 km\/h or less.<\/p>\n

<\/p>\n

1.3<\/p>\n

Braking system performance requirements and proof tests are not included in the Scope of this Standard, except from the standpoint of the reduction of fire and explosion hazards.<\/p>\n

<\/p>\n

Note: See CAN\/CSA-M424.3 for brake construction, stopping performance, and test requirements.<\/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":"
