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.

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.

CSA B137.10:23 - Crosslinked polyethylene/aluminum/crosslinked polyethylene (PEX-AL-PEX) composite pressure-pipe systems

Preface

This is the tenth edition of CSA B137.10, Crosslinked polyethylene/aluminum/crosslinked polyethylene (PEX-AL-PEX) composite pressure-pipe systems, which supersedes the previous editions published in 2020, 2017, 2013, 2009, 2005, 2002, 1999, 1998, and 1991.

This Standard is to be used with the 2023 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 to this edition include

a) updated clause references for carbon black requirement;

b) revision to excessive temperature and pressure capability test; and

c) revision to hydrostatic burst test.

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 General

This Standard covers crosslinked polyethylene/aluminum/crosslinked polyethylene (PEX-AL-PEX) macrocomposite pipe consisting of a welded aluminum (AL) tube laminated by a melt adhesive to layers of crosslinked polyethylene (PEX) inside and outside the aluminum tube. This Standard also covers fittings (connectors) for use with PEX-AL-PEX pipe. The pipes covered in this Standard are pressure rated for 1380 kPa at 23 °C or 860 kPa at 82 °C, or both.

Systems are intended for use in potable water distribution systems or other applications, including municipal water service lines, reclaimed water distribution, radiant panel heating systems, hydronic baseboard heating systems, snow and ice melting systems, building services piping, compressed air distribution, ground source geothermal systems, underground irrigation, and compressed gas distribution (not including fuel gases), provided that the PEX-AL-PEX systems comply with the applicable code requirements. Residential and commercial systems are included.

Note: The complete structure, consisting of the aluminum, melt adhesive, and layers of crosslinked polyethylene intimately bonded together, is known as pipe. For the purposes of this Standard, the layer of welded aluminum, or the internal and external layer of crosslinked polyethylene, is known as a tube. Tubes, intimately bonded together by the melt adhesive, form a pipe.

1.2 Requirements

This Standard specifies requirements for materials, quality of work, dimensions, thermocycling resistance, sustained pressure performance, delamination resistance, and marking.

Notes:

1) In developing the hydrostatic design basis for PEX-AL-PEX pipes, in accordance with CSA B137.0, pressure has been substituted for fibre stress.

2) The pressure rating of PEX-AL-PEX pipes is contingent on the thickness of the aluminum metal reinforcing layer. Pipes having the same dimension ratio but different metal reinforcing layer thicknesses will have different pressure ratings. The dimension ratio therefore cannot be used, as it is with homogeneous walled pipes, to assess changes in pressure rating with wall thickness variation.

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.
