D2665-24 – Standard Test Method Technical Guide
ASTM D2665-24 is an American National Standard that specifies requirements for poly(vinyl chloride) (PVC) plastic drain, waste, and vent (DWV) pipe and fittings. It covers materials, dimensions and tolerances, pipe stiffness, crush resistance, impact resistance, and solvent cement properties. The standard also includes marking guidelines and references installation procedures in the appendix. It is issued under the fixed designation D2665 and was last approved in 2024.
📐 Scope and Material Specifications
The scope of D2665-24 defines requirements for PVC DWV pipe and fittings, excluding plastics that do not meet material specifications in Section 5. Materials must comply with Classification System D1784 for rigid PVC compounds. Dimensions and tolerances are measured per Test Method D2122, pipe stiffness and crush resistance via Test Method D2412, impact resistance by Practice D2444, and solvent cement per Specification D2564. Values are standard in inch-pound units.
The standard uses inch-pound units as the primary basis; SI values are provided mathematically for reference only. Always verify unit systems when interpreting requirements.
⚙️ Testing Methods and Performance Criteria
Testing is integral to this specification. Dimensions are determined using Test Method D2122. External loading characteristics, including pipe stiffness and crush resistance, are evaluated with Test Method D2412 under parallel-plate loading. Impact resistance is assessed by means of a falling tup per Practice D2444. Solvent cement joints must conform to Specification D2564. Conditioning of specimens follows Practice D618 to ensure consistent test results.
| 🟦 Requirement | 📏 Test Method | 📐 ASTM Reference |
|---|---|---|
| Dimensions and Tolerances | Test Method D2122 | D2122 |
| Pipe Stiffness & Crush Resistance | Test Method D2412 | D2412 |
| Impact Resistance | Practice D2444 | D2444 |
| Solvent Cement | Specification D2564 | D2564 |
Safety hazard: This standard does not address all safety concerns. Practice safe handling of solvent cements per F402 and establish appropriate health, safety, and environmental practices before use.
