This practice describes a two-step (primer and solvent cement)
method of joining poly(vinyl chloride) (PVC) or chlorinated
poly(vinyl chloride) (CPVC) pipe and piping components with tapered
NOTE 1—Simplified procedures may be allowed in non-pressure
applications where local codes permit.
NOTE 2—Where conflicts occur between the code and the
manufacturer’s installation instructions, the more restrictive
The products covered by this practice are intended for use with
the distribution of pressured liquids only, which are chemically
compatible with the piping materials. Due to inherent hazards
associated with testing components and systems with compressed air
or other compressed gases, some manufacturers do not allow
pneumatic testing of their products. Consult with specific
product/component manufacturers for their specific testing
procedures prior to pneumatic testing.
NOTE 3—Pressurized (compressed) air or other compressed gases
contain large amounts of stored energy which present serious safety
hazards should a system fail for any reason.
This standard practice does not address the one-step method of
joining pipe and piping components with tapered sockets with
solvent cement without the use of primer.
The techniques covered are applicable to joining PVC to PVC or
CPVC to CPVC pipe and piping components with tapered sockets. In
the remainder of this standard practice, the term “piping
components with tapered sockets”, whether it be bell end pipe,
spigot connections, or any other type of tapered connections, will
be referred to as “fittings.”
A partial list of standards for PVC and CPVC pipe, piping
components, and solvent cements suitable for use in joining pipe
and fittings is given in Appendix X1.
The values stated in inch-pound units are to be regarded as
standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and
are not considered standard.
The text of this practice references notes and footnotes that
provide explanatory material. These notes and footnotes (excluding
those in tables and figures) shall not be considered as
requirements of the practice.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
