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.

B137.0-09 Definitions, general requirements, and methods of testing for thermoplastic pressure piping

1 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.

Note: The terms “pipe” and “piping”, as well as “tube” and “tubing”, are used interchangeably in the CSA B137 Series.

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 CSA Standards, “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; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. 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.

B137.1-09 Polyethylene (PE) pipe, tubing, and fittings for cold-water pressure services

1 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.

B137.2-09 Polyvinylchloride (PVC) injection-moulded gasketed fittings for pressure applications

1 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 (Class 150), covered in this Standard 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.

B137.3-09 Rigid polyvinylchloride (PVC) pipe and fittings for pressure applications

1 Scope

1.1

This Standard covers rigid polyvinylchloride (PVC) pipe and fittings intended for use in pressure applications such as water mains, water service piping, and process piping. The fittings covered by this Standard include moulded, solvent-cemented, gasketed, or threaded fittings, and fittings that have been fabricated for use with any joining method. Note: Where PVC pipe and fittings are to be used in non-water applications, the manufacturer should be consulted.

1.2

This Standard specifies requirements for materials, quality of work, dimensions, solvent cement, and markings for pipe and fittings. Requirements for hydrostatic sustained pressure, extrusion, impact resistance, and quality are also specified for pipe.

B137.3.1-09 Molecularly oriented polyvinylchloride (PVCO) pipe for pressure applications

Scope

1.1

This Standard covers molecularly oriented polyvinylchloride (PVCO) pipe intended for use in pressure applications such as water mains, sewer force mains, and process piping. Note: This Standard does not address chemical compatibility between PVCO pipe and process fluids. Where PVCO pipe is to be used in non-water applications, the manufacturer should be consulted.

1.2

PVCO complying with this Standard is not suitable for solvent cementing and is intended to be joined by gasketed joints. 1.3 This Standard specifies requirements for materials, quali
