Title
Standard Specification for Chlorinated Poly(Vinyl Chloride) (CPVC) Plastic Pipe, Schedules 40 and 80
ASTM International
Publication Date:
Aug 1, 2009
Scope:
This specification covers chlorinated poly(vinyl chloride)
(CPVC) pipe made in Schedule 40 and 80 sizes and pressure-rated for
water (see appendix). Included are criteria for classifying CPVC
plastic pipe materials and CPVC plastic pipe, a system of
nomenclature for CPVC plastic pipe, and requirements and test
methods for materials, workmanship, dimensions, sustained pressure,
burst pressure, flattening, and extrusion quality. Methods of
marking are also given.
NOTE 1—The CPVC pipe covered by this specification was covered
previously in Specification D 1785.
NOTE 2—The sustained and burst pressure test requirements, and
the pressure ratings in the appendix, are calculated from stress
values obtained from tests made on pipe 2 in. [50 mm] and smaller.
However, tests on larger pipe have shown these stress values to be
valid.
The products covered by this specification are intended for use
with the distribution of pressurized 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 saftey
hazards should a system fail for any reason.
The text of this specification references notes, footnotes, and
appendixes which provide explanatory material. These notes and
footnotes (excluding those in tables and figures) shall not be
considered as requirements of the specification.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
The following safety hazards caveat pertains only to the test
methods portion, Section 8, of this specification: 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. A specific precautionary statement is given in
Note 7.
*A Summary of Changes section appears at the end of this
standard.
