Preface

This is the ninth edition of CSA B137.2, Polyvinylchloride (PVC) injection-moulded gasketed fittings for pressure applications, which supersedes the previous editions published in 2017, 2013, 2009, 2005, 2002, 1999, 1993, and 1989.

While earlier editions of this Standard were published as part of the CSA B137 Series, Thermoplastic pressure piping compendium, the eighth 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 change in this new edition is the addition of B137.0 to Reference Publications in Clause 2.

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 rigid polyvinylchloride (PVC) injection-moulded fittings that have gasketed joints and are intended for use in pressure applications such as water mains, water service piping, process piping, and fire lines. Fittings covered by this Standard are suitable for use with PVC pipes having outside diameter dimensions of cast iron pipe. Only one pressure rating, 1620 kPa at 23 °C (PC 235), is covered in this Standard and is suitable for use with compatible outside diameter PVC pipes having a dimension ratio (DR) of 18 or more.

Note: Where PVC fittings are to be used in applications other than those involving water, the manufacturer should be consulted.

1.2

This Standard specifies requirements for materials, quality of work, long-term performance under sustained hydrostatic pressure, dimensions, markings, and injection-moulding quality.

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.
