ASTM F442/F442M-23 PDF

Full title and description

ASTM F442/F442M-23 — Standard Specification for Chlorinated Poly(Vinyl Chloride) (CPVC) Plastic Pipe (SDR–PR). This specification establishes classification, material and workmanship requirements, dimensions, sustained and burst pressure tests, flattening resistance, extrusion quality, and marking for CPVC pipe intended for distribution of pressurized water and other chemically compatible liquids.

Abstract

This specification covers CPVC pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (SDR–PR). It provides criteria for classifying CPVC materials and finished CPVC pipe, and specifies associated test methods and requirements for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening resistance, extrusion quality, and marking. The standard includes both inch‑pound and SI units (shown in brackets) and contains safety and testing caveats.

Scope

The standard applies to chlorinated poly(vinyl chloride) (CPVC) pipe manufactured in standard dimension ratios and pressure ratings intended for the distribution of pressurized liquids (water and other liquids that are chemically compatible with CPVC). It defines classification criteria for CPVC materials and finished pipe and sets test methods and requirements for sustained and burst pressure, flattening resistance, dimensional tolerances, extrusion quality, workmanship, and marking. Appendix material provides pressure‑rating calculations and related guidance.

Key topics and requirements

• Material classification and composition requirements for CPVC pipe compounds.
• Dimensional requirements and tolerances for standard dimension ratio (SDR) pipes.
• Sustained‑pressure and burst‑pressure testing procedures and acceptance criteria.
• Flattening (ring‑flex) resistance and extrusion quality criteria.
• Marking, identification, and unit‑handling guidance for finished pipe.
• Use of both inch‑pound and SI units (values in each system are to be treated separately).
• Safety caveats related to pneumatic testing and general user responsibility for safe use.

Typical use and users

Manufacturers of CPVC pressure pipe and piping systems, product design and quality engineers, testing laboratories, plumbing and mechanical specifiers, contractors, and regulators who require standardized requirements for CPVC pressure piping used in water distribution and other compatible liquid services. It is used for specification writing, product acceptance, and test method reference.

FAQ

Q: What is this standard?

A: ASTM F442/F442M‑23 is the ASTM International specification that defines requirements and test methods for chlorinated poly(vinyl chloride) (CPVC) plastic pipe produced in standard dimension ratios and pressure ratings for the distribution of pressurized liquids, primarily water.

Q: What does it cover?

A: It covers material classification, dimensional tolerances, sustained and burst pressure performance, flattening resistance, extrusion quality, workmanship, and marking for CPVC SDR pressure‑rated pipe; it also provides appendixes for pressure‑rating calculations and includes safety notes on testing.

Q: Who typically uses it?

A: Pipe manufacturers, QA/QC and R&D engineers, test laboratories, specifiers, contractors, and authorities having jurisdiction who need a normative specification for CPVC pressure pipe.

Q: Is it current or superseded?

A: The designation F442/F442M‑23 is the 2023 edition and is listed as active/published (current) as of its publication on February 1, 2023. Users should check for any later amendments or revisions before citing it for procurement or compliance.

Q: Is it part of a series?

A: It is maintained by ASTM Committee F17 on Plastic Piping Systems (Subcommittee F17.25 on vinyl‑based pipe) and is related to other F17 standards covering PVC/CPVC piping materials, test methods, and system practices. The standard replaces earlier F442/F442M editions and references earlier related specifications (for example, D2241 historically covered some of these products).
