CAN/CSA-B137 Series-13
Thermoplastic pressure piping compendium
1.1
This Standard specifies requirements for polyethylene of raised temperature (PE-RT) tubing systems that
are comprised of tubing and fittings.
Tubing covered by this Standard is made in Standard Dimensional Ratio 9 (SDR 9).
Systems are pressure rated at two temperatures: 1105 kPa at 23 °C and 690 kPa at 82 °C. Systems are
intended for use in potable water distribution systems or other applications, including municipal water
service lines, reclaimed water distribution, radiant panel heating and cooling systems, hydronic baseboard
heating systems, snow and ice melting heating systems, building services piping, compressed air
distribution, and ground source geothermal systems, provided that the PE-RT tubing systems covered in
this Standard comply with the applicable code requirements. Residential and commercial systems are
included.
Note: The requirements and test methods specified in this Standard can involve hazardous materials, operations, and
equipment. This Standard does not purport to address all potential safety problems associated with its use. Before using this
Standard, users are responsible for establishing appropriate safety and health practices and determining the applicability of
any regulatory limitations.
