Standard Specification for 3.25-in. Outside Diameter Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings
SCOPE 1.1 This specification covers requirements and test methods for materials, dimensions and tolerances, deflection load, crush resistance, flattening resistance, impact resistance, and solvent cement. A form of marking is also included. Plastic which does not meet the material requirements specified in Section 5 is excluded. Note 1: This specification was formerly issued under the title, 3-in. Thin Wall Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings. 1.1.1 Techniques for making solvent-cement joints are given in Practice D2855. 1.2 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. 1.3 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. 1.4 The following precautionary caveat pertains only to the test methods 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. 1.5 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.
ASTM D2949-22: Standard Specification for 3.25-in. Outside Diameter Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings provides requirements for PVC pipes and fittings used in drain, waste, and vent (DWV) systems. Issued by ASTM International, this standard ensures consistent performance and safety across commercial and residential plumbing applications. The specification includes criteria for materials, dimensions, tolerances, mechanical strength, solvent cement, markings, sampling, and quality assurance. It is widely recognized in the plumbing industry for facilitating reliable and safe wastewater management.

ASTM D2949-22 is essential for developers, contractors, and manufacturers of plumbing systems, particularly for:
Residential Wastewater Drainage Utilized in toilet, sink, and tub drain assemblies for safe and efficient waste conveyance.
Commercial Buildings Appropriate for multi-story and high-occupancy structures requiring reliable DWV infrastructure.
Retrofit and Replacement Suitable for upgrades in older buildings replacing non-plastic or incompatible piping systems.
Industrial Waste Lines (Limited) May be applied in non-chemical industrial drainage lines with building code approval.
Transition Fittings Includes specifications for adapters connecting PVC to cast iron or other materials.
Correct installation, handling, and storage practices-such as minimizing sunlight exposure and ensuring proper pipe support-are critical to maximize performance and longevity.
For comprehensive design, installation, and testing, these ASTM standards are referenced and work in conjunction with ASTM D2949-22:
Using components certified to ASTM D2949-22 enhances safety, performance, and code compliance in DWV installations. The standard’s rigorous requirements support long-term reliability and help minimize plumbing failures, leaks, and associated property damage. Through unified testing and marking practices, it ensures consistent quality across the supply chain, benefiting manufacturers, contractors, and end-users alike.
