Preface

This is the eleventh edition of CSA B137.1, Polyethylene (PE) pipe, tubing, and fittings for cold-water pressure services. It supersedes the previous editions published in 2017, 2013, 2009, 2005, 2002, 1999, 1995, 1989, 1983, and 1970.

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.

This Standard is to be used with the 2020 edition of CSA B137.0, which provides requirements and test methods that are common to some or all of the Standards of the CSA B137 series.

The major changes in this new edition are

a) The addition of Series 250 pipe to Clause 5.1.3.1 and Tables 5 and 7; and

b) The addition of Series 250 tubing to Clauses 5.1.3.1 and 5.1.3.3, and Table 6.

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 covers polyethylene (PE) pipe, tubing, and fittings for use in potable cold water supply services or other applications such as water-based ground source geothermal systems.

1.2

This Standard specifies requirements for materials, quality of work, dimensions, sustained pressure, environmental stress cracking, and markings.

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.
