ASTM Standard F1970
This standard covers fittings and appurtenances intended to be
used in PVC or CPVC plastic piping, or as a transition from such
systems to metal systems. These products, such as unions,
flanges, or valves, are not included in the scope of other ASTM
specifications.
ASME B1.20.1 (American Society of Mechanical
Engineers)
This specification details the dimensions, tolerances, and
gaging of tapered pipe threads used on metallic ends of pipe
and fittings, plus machined plastic threaded ends.
NSF/ANSI Standard 14 (NSF International)
This standard establishes the minimum physical and performance
requirements for plastic piping system components and related
materials. It also provides a basis for certification of products
to consensus standards, or other physical and performance
requirements where no consensus standard exists. It requires
adherence to appropriate ASTM Standards and specifies
minimum quality control programs. To comply with this standard
the manufacturer must allow periodic testing of product and
auditing of procedures by a third-party agency.
NSF/ANSI Standard 372
This standard establishes procedures for determination of lead
content based on the wetted surface area within the product.
This standard is used in conjunction with NSF/ANSI 61 for
the purpose of compliance with the Safe Drinking Water Act
(SDWA), the federal law that ensures the quality of America's
public drinking water supply.
NSF/ANSI Standard 61
At the request of the U.S. Environmental Protection Agency (EPA),
a consortium led by NSF International developed this standard.
It was developed to establish minimum requirements for the
control of potential adverse human health effects from products
which contact drinking water. This Standard complements the
performance requirements that are contained within ASTM
product standards. NIBCO

PVC & CPVC fitting products intended
for potable water applications are tested and certified by a third-
party agency for compliance to ANSI/NSF Standard 61.
CSA (Canadian Standards Association)
CSA Group has several codes including the Canadian Plumbing
Code as well as numerous standards. Several third party agencies
provide testing and certification to show compliance with these
codes and standards. For further information on third party listings
contact NIBCO customer service.
IAPMO (International Association of Plumbing and
Mechanical Officials)
IAPMO has several codes including the Uniform Plumbing Code
(UPC). Many products are third party tested and listed showing
compliance to this code by one or more third party agencies. For
further information contact NIBCO customer support.
Chemical Resistance
Thermoplastics exhibit a ‘GO’ or ‘NO-GO’ type of resistance when
contacted by aggressive chemicals. That is, they either resist
attack completely or they deteriorate rapidly, in which case,
the mechanism of attack is either solvation or reaction with the
base molecule. Solvation, which is the most common form of
attack, involves penetration of a chemical into the plastic causing
softening, swelling, and loss of physical properties. Reaction with
the base molecule involves the breakage of the molecular chain,
crosslinking, or substitution reactions.
The NIBCO Chemical Resistance Guide contains specific chemical
resistance information for the various plastic and elastomeric
materials used in the NIBCO product line. When interpreting the
information presented in this brochure it is important to note that it
is based only on unstressed immersion testing at the temperatures
noted, using pure chemicals or saturated solutions, except where
otherwise specified. It is unwise to specify a plastic material
without chemical resistance information relative to the specific
environment of the intended application. Therefore, in situations
where the aggressive environment involves a mixture of chemicals,
the Chemical Resistance Guide can be used to investigate the
effects of individual chemicals; however, because of possible
synergisms, the suitability of a particular plastic for handling
a chemical mixture should be verified. Also, since chemicals
are more aggressive at higher temperatures and concentrations,
chemical resistance information should not be extrapolated to
higher temperatures and concentrations. Conversely, chemicals are
generally less aggressive at lower temperatures and concentrations;
therefore, extrapolation of chemical resistance information to lower
temperatures and concentrations is generally acceptable.
When chemical resistance information is not available or a first-of-
a-kind process is involved, data may be obtained through immersion
testing. ASTM D543 provides a method for conducting such tests,
and the chemical, as well as, the temperature used in this test
should be identical to the anticipated process condition.
