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

<\/p>\n

This is the first edition of CSA\/ANSI CHMC 2, Test methods for evaluating material compatibility in compressed hydrogen applications \u2014 Polymers.<\/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

This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.<\/p>\n

<\/p>\n

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

<\/p>\n

1.1<\/p>\n

This Standard provides uniform test methods for evaluating material compatibility in compressed hydrogen applications. The results of these tests are intended to provide a basis for comparison of materials performance in applications using compressed hydrogen.<\/p>\n

<\/p>\n

1.2<\/p>\n

This Standard applies to polymer materials only.<\/p>\n

<\/p>\n

Note: In this Standard, the term polymer refers to synthetic polymers, such as thermoplastics and elastomers, that have been manufactured for liner or sealing applications.<\/p>\n

<\/p>\n

1.3<\/p>\n

This Standard is not intended to replace sound engineering judgment or component testing in hydrogen applications; additional testing considerations based on applicable standards and relevant failure modes should be conducted to fully qualify the polymer in the design of a component manufactured for use in certain hydrogen applications.<\/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

<\/p>\n

1.5<\/p>\n

All references to pressure throughout this Standard are to gauge pressures, unless otherwise specified.<\/p>\n","protected":false},"excerpt":{"rendered":"
