Preface

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

While earlier editions of this Standard were published as part of the CSA B137 Series, Thermoplastic pressure piping compendium, the tenth edition was reissued as a stand-alone Standard in January 2019. The compendium format has been discontinued.

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 in this new edition are

a) Addition of Note 2) to Clause 1.1 for the exclusion of venting of combustion gas applications;

b) Revision to the definition for polypropylene to Clause 3;

c) Clarification of test temperature in Clause 6.6.4.2.2; and

d) Revision to fitting marking requirements in Clause 7.2.1c).

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

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

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

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

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