CSA B137.0:23 - Definitions, general requirements, and methods of testing for thermoplastic pressure piping

Preface

This is the twelfth edition of CSA B137.0, Definitions, general requirements, and methods of testing for thermoplastic pressure piping. It supersedes the previous editions published in 2020, 2017, 2013, 2009, 2005, 2002, 1999, 1993, 1986, 1981, and 1973.

CSA B137.0 provides requirements and test methods that are common to some or all of the Standards of the CSA B137 Series. Wherever possible, individual Standards make reference to the relevant clauses in CSA B137.0.

The major changes to this edition include

a) revision to humidity tolerances;

b) revision to chemical resistance test; and

c) revisions to Clause 6.6for hydrostatic sustained pressure test, including

i) additional reference standards and additional details for testing and analysis;

ii) new clause 6.6.3.5 for compounds;

iii) revision to Clause 6.6.4.1.2 for PE-RT compound validation; and

iv) revision to Clause 6.6.4.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

This Standard was prepared by the Technical Committee on Plastic Pressure Piping, under the jurisdiction of the Strategic Steering Committee on Construction and Civil Infrastructure, and has been formally approved by the Technical Committee.

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.

Scope

1.1 Scope of this Standard

This Standard specifies requirements for thermoplastic pressure piping. It includes reference publications, definitions, abbreviations, general requirements for materials and manufactured pipe and fittings, relevant test methods, and marking requirements.

Notes:

1) The terms pipe and piping, as well as tube and tubing, are used interchangeably in the CSA B137 Series.

2) This Standard does not specify requirements for venting of combustion gases. In Canada, ULC S636 specifies testing and marking requirements for pipe, fittings, and accessories intended for venting of combustion gases. In the United States, UL 1738 specifies testing and marking requirements for pipe, fittings, and accessories intended for venting of combustion gases.

1.2 Intent of this Standard

This Standard is intended to be used in conjunction with one of the other Standards in the CSA B137 Series to form a complete Standard for a particular product.

1.3 Terminology

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.

1.4 Units

Values are given in SI units. Table C.1provides conversion factors for inch-pound (IP) units.
