Description

Preface

This is the eighth edition of CSA B137.4.1, Electrofusion-type polyethylene (PE) fittings for gas services, which supersedes the previous editions published in 2017, 2013, 2009, 2005, 2002, 1999, and 1989.

While earlier editions of this Standard were published as part of the CSA B137 Series, Thermoplastic pressure piping compendium, the seventh 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 socket- and saddle-type polyethylene (PE) electrofusion fittings that are used to join PE pipe where the heat source is an integral part of the fitting.

Note: Fittings covered by this Standard are connected to an electrical power source during the fusion process. Power sources, cables, and electrical connections are covered by the Canadian Electrical Code, Part I and Part II, as appropriate.

1.2

PE electrofusion fittings covered by this Standard are intended for use with PE pipe that complies with CSA B137.4.

1.3

This Standard specifies general requirements for materials, performance, manufactured fittings, specimen preparation, test methods, markings, and quality of work.

Notes:

1) In this Standard, pipe refers to pipe having IPS outside diameters and tubing refers to pipe having copper tube outside diameters.

2) In this Standard, test requirements for pipe apply to both pipe and tubing.

1.4

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.
