Preface 

This is the third edition of CSA/ANSI LC 4 – CSA 6.32, Press-connect fittings and valves for use in fuel gas distribution systems. It supersedes the previous editions published in 2012 and 2007 and addenda A in 2013. This new edition includes an update to the title, revision to Clause 4.3. c) and a revision to 5.2.2.1 to clarify valve position. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. 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. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. 

Scope 

1.1 This Standard applies to metallic (copper, steel, stainless steel, and malleable iron) press-connect type fittings, and valves (hereafter referred to as fittings unless otherwise specified) for use with fuel gas systems intended for installation above ground, below ground, indoors, and outdoors. 

1.2 This Standard applies to fuel gas systems rated for operating pressures not exceeding 125 psi (862 kPa). 

1.3 This Standard applies to fittings intended for use with fuel gas systems 3/8 in through 4 in nominal size. 

1.4 Fittings and other components complying with the provisions of this Standard shall be considered as having an ambient temperature range of minus 40 °F (-40 °C) to 180 °F (82.2 °C). 

1.5 This Standard includes requirements to establish the suitability for use in concealed locations (see Clause 3). 

1.6 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. 

1.7 If a value for measurement as given in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification. This document is based on yard/pound quantities with SI equivalents provided as a guide for making metric conversions. Note: See Annexes A and B.
