Standards and Listings

Heating PEX:

requirements and testing methods for materials, workmanship, dimensions, environmental stress cracking, sustained hydro-

static pressure strength, bend strength, and degree of cross-linking. Heating PEX meets or

exceeds these standards.

– Heating PEX is tested and listed to UL 263 (Fire Tests of Building Construction and Materials) by Intertek.

 –HeatingPEXislistedbytheInternationalCodeCouncilEvaluationService(ICC)toReport#ESR-1155,andPMG-1008which

give compliance to IPC/IMC, and UPC/UMC.

 –HeatingPEXiscertiedtoCSAStandardB137.5.

Expansion Rate: 1.1"/100'/10°F.

Allow 1/8" slack for every foot of installed tubing.

The bend radius for Heating PEX may require some

bends to be “light bulb” in shape. This method

allows for tighter on center spacing without

compromising the tubing.

Expansion Rate: 0.156”/100’/10°F.

Note: No special considerations required to account for thermal expansion.

The bend radius for Heating PEX-AL-PEX is slightly

tighter than Heating PEX but may still require some

bends to be “light bulb” in shape. It is important,

however, to ensure the minimum bend radius is not

exceeded, as this will cause the tubing to kink. This

method allows for tighter on center spacing without

compromising the tubing.
