2.2 Standards
ASTM — American Society for Testing and Materials
ASTM F876/F2023: Standard Specification for
Cross-linked Polyethylene (PEX) Tubing — This
standard contains nite dimensional requirements
for SDR9 PEX tubing in addition to burst, sustained
pressure, chlorine resistance and other relevant
performance tests at different water temperatures.
ASTM F877: Standard Specification for Cross-
linked Polyethylene (PEX) Plastic Hot- and Cold-
Water Distribution Systems — This standard
contains performance requirements for SDR9 PEX
tubing and tting systems. The standard contains
nite dimensional requirements for tubing, in addition
to burst, sustained pressure and other relevant
performance tests at different water temperatures.
ASTM E84 — Standard Test Method for Surface
Burning Characteristics of Building Materials
ASTM E119 — Standard Test Method for Fire
Testing of Building Construction and Materials
ASTM E814 — Standard Test Method for Fire Test
of Through-Penetration Firestop Systems
NSF International
ANSI/NSF 14: Plastics Piping System Components
and Related Materials — This standard establishes
minimum physical and performance requirements for
plastic piping components and related materials. These
criteria were established for the protection of public
health and the environment.
ANSI/NSF 61: Drinking Water System
Components — Health Effects — This standard
establishesminimum health effects requirements for the
chemical contaminants and impurities that are indirectly
imparted to drinking water from products, components
and materials used in drinking water systems. This
standard does not establish performance or taste and
odor requirements for drinking water system products,
components ormaterials.
American Water Works Association (AWWA)
AWWA C904 — Cross-linked Polyethylene (PEX)
Pressure Pipe, ½" through 2" for Water Service
ISO — International Standards Organization
ISO 9001This standard is intended to establish,
document and maintain a system for ensuring
production output quality. ISO 9001 certication is a
tangible expression of a rm’s commitment to quality
that is internationally understood and accepted. All
PureFlow PEX Press ttings are manufactured in
ISO9001 certied facilities.
