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) Schedule 40 pipe fittings. Included are requirements for materials,
workmanship, dimensions, and burst pressure.
NOTE 1—Socket-type CPVC plastic pipe fittings, Schedule 40, which were formerly included in this standard, are now covered by Specification F438.
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 2—Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safteysafety hazards
should a system fail for any reason.
1.3 Fitting such as unions, flanges, special plastic-to-metal transitions and appurtenances intended for use with PVC piping are
covered under specificationSpecification F1970.
1.4 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.
1.5 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.
1.6 The following safety hazards caveat pertains only to the test method portion, Section 7, 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, health, and environmental practices and determine the applicability of regulatory
limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
This specification is under the jurisdiction of ASTM Committee F17 on Plastic Piping Systems and is the direct responsibility of Subcommittee F17.10 on Fittings.
Current edition approved April 1, 2021July 1, 2023. Published April 2021August 2023. Originally approved in 1965. Last previous edition approved in 20172021 as
D2466 – 17.D2466 – 21. DOI: 10.1520/D2466-21.10.1520/D2466-23.

three ribs extending from the top of the inner socket to the deepest extremity of the coring. The transition from D to DJ (Table
3) shall be straight, tapered as shown, or radiused. A positive taper in the same direction of the taper in the socket on the outside

6.1.3 The minimum body wall thickness of fittings shall be 125 % of the minimum wall thickness of the corresponding size of
Schedule 40 pipe for which they are designed to be used, except that for used. For the socket, the wall thickness shall be at least
equal to the minimum wall thickness of the corresponding size of Schedule 40 pipe. pipe, except in fittings designed with a socket
nested in a spigot such as reducer bushings or nesting couplings. For any threaded fitting the minimum wall thickness of the
threaded portion shall be at least equal to the thickness of material under the thread root of threaded Schedule 80 pipe of the same
