Quality Assurance
ViegaPEX Barrier tubing is manufactured and tested
to the requirements of ASTM F876, F877 and CSA
B137.5. The degree of cross-linking of nished tubing is
determined by method ASTM D2765.
Certifications
- Tested for health effects to ANSI/NSF standard 61
and performance to ANSI/NSF standard 14.
- Products meet all applicable performance
requirements for a pressure rated oor heating
application specied in NSF/ANSI Standard 14.
PEX 5306 - Tested and listed to the NSF-pw (CL5) Chlorine
resistance rating for an end use condition of 100% @ 140°F
per ASTM F876, which is the highest Chlorine resistance rating
available through ASTM. When the product is marked with the
PEX 5306 NSF-pw (CL5) designation, it afrms the product is
approved for use in continuous domestic hot water circulation
systems with up to 140°F water temperatures.

- ICC ES-PMG™ 1015
Hydronic Piping
- NSF certified to CSA B137.5
(Canadian Standards Association)
- Certified to ASTM E84 and CAN/ULC S102.2
FS/SD (25/50) (US & Canadian plenum rating)
- Certified to UL 263 & CAN/ULC S101

Tube Spacing
When the tube spacing is less than the minimum
recommended bending dimension, the loops ends should
be swept out to at least the dimensions shown.
Otherwise, if tube spacing is equal or greater than “X,” a
standard loop may be used.
ViegaPEX Barrier Oxygen Permeation
All sizes have less than 0.1 gram/m³/day
Note: ViegaPEX Barrier tubing meets DIN 4726
requirements for oxygen tight pipes.
