D2467-24 – Standard Test Method Technical Guide
ASTM D2467-24 is the latest revision of the standard specification governing Poly(Vinyl Chloride) (PVC) Schedule 80 plastic pipe fittings. This document establishes the requirements for materials, workmanship, dimensions, and burst pressure to ensure reliable performance in pressurized liquid systems. This standard has been approved for use by agencies of the U.S. Department of Defense and conforms to internationally recognized standardization principles.
📐 Scope and Material Classification
This specification covers PVC Schedule 80 pipe fittings intended for use exclusively with the distribution of pressurized liquids that are chemically compatible with the piping materials. The values stated in inch-pound units are to be regarded as standard, while values given in parentheses are mathematical conversions to SI units provided for information only. All materials used must conform to the Classification System D1784 for rigid PVC compounds. The text also provides an important update regarding product scope—CPVC Schedule 80 fittings, formerly part of this standard, are now covered exclusively under Specification F439. Dimensional symbology follows the conventions of Specification D2749, while terminology is standardized in F412.
💡 Historical Scope Note: Chlorinated Poly(Vinyl Chloride) (CPVC) Schedule 80 pipe fittings were previously included in D2467. They are now fully governed by the separate ASTM Specification F439.
⚙️ Dimensional Verification and Burst Pressure Performance
To ensure proper fit and function with Schedule 80 PVC pipe (Specification D1785), all fittings must meet strict dimensional tolerances. Test Method D2122 is used to verify critical measurements including socket depth, wall thickness, and overall geometry. Threaded fittings must conform to Specification F1498 which governs 60° Taper Pipe Threads for thermoplastic materials.
The primary performance requirement is burst pressure. Section 8 of the standard dictates that fittings be tested in accordance with Test Method D1599 (Resistance to Short-Time Hydraulic Pressure) to validate that each product meets the specific minimum burst pressures tabulated in the standard. Fittings intended for potable water applications must also demonstrate compliance with NSF Standard 14 (Plastic Piping Components) and NSF Standard 61 (Drinking Water System Components—Health Effects).

| Potable Water | NSF Std. 14 & 61 | Compliance required for fittings used in drinking water systems. |
⚠️ Application Guidelines and Safety Hazards
The standard strictly restricts the products to the distribution of pressurized liquids only. A critical safety caveat is provided regarding the use of compressed air or other compressed gases. Pressurized compressed gases contain large amounts of stored energy, which presents serious safety hazards should a system fail. Because of these inherent hazards, the standard notes that some manufacturers do not allow pneumatic testing of their products. The standard strongly recommends consulting the specific product/component manufacturer for their specific testing procedures prior to any pneumatic testing or pressurization with gases.
⚠️ Critical Safety Hazard: Pressurized (compressed) air or other compressed gases contain large amounts of stored energy, which present serious safety hazards should a system fail. Always consult the specific manufacturer for their testing procedures prior to pneumatic testing.
❓ Frequently Asked Questions
🔍 What products are covered under ASTM D2467-24?
This standard specifically covers Poly(Vinyl Chloride) (PVC) Schedule 80 pipe fittings. These fittings are intended for use with the distribution of chemically compatible pressurized liquids.
💡 Are CPVC fittings still included in this specification?
No. Chlorinated Poly(Vinyl Chloride) (CPVC) Schedule 80 pipe fittings, which were formerly included in this standard, are now covered by the separate ASTM Specification F439.
⚡ What test method is used to verify burst pressure?
The standard mandates the use of Test Method D1599 (Resistance to Short-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings) to validate the minimum burst pressure of the fittings.
📌 Why does the standard warn against pneumatic testing?
Pressurized compressed air and other gases contain large amounts of stored energy. A failure during pneumatic testing presents a serious risk of catastrophic equipment failure and severe injury. The standard advises consulting the manufacturer for approved testing protocols.
