ASTM D1785-15

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D1785 − 12 D1785 − 15 An American National Standard
Standard Specification for
Poly(Vinyl Chloride) (PVC) Plastic Pipe, Schedules 40, 80,
1
and 120
This standard is issued under the fixed designation D1785; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 This specification covers poly(vinyl chloride) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-rated for
water (see Appendix X1). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of
nomenclature for PVC 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.
1.2 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 1—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.
NOTE 2—This standard specifies dimensional, performance and test requirements for plumbing and fluid handling applications, but does not address
applications only. It does not include provisions for the use of these products for venting of combustion gases. UL 1738 is a standard that does include
specific testing and marking requirements for flue gas venting products, including PVC.
1.3 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.
1.4 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.
1.5 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 9.
NOTE 3—CPVC plastic pipes, Schedules 40 and 80, which were formerly included in this specification, are now covered by Specification F441/F441M.
NOTE 4—The sustained and burst pressure test requirements, and the pressure ratings in the Appendix X1, are calculated from stress values obtained
from tests made on pipe 4 in. (100 mm) and smaller. However, tests conducted on pipe as large as 24-in. (600-mm) diameter have shown these stress
values to be valid for larger diameter PVC pipe.
NOTE 5—PVC pipe made to this specification is often belled for use as line pipe. For details of the solvent cement bell, see Specification D2672 and
for details of belled elastomeric joints, see Specifications D3139 and D3212.
