ASTM D2239 Polyethylene Plastic Pipe Testing – Controlled Inside Diameter
ASTM D2239 test method applies to water-rated polyethylene (PE) pipe with standard interior dimension ratios (SIDR) (see appendix). Workmanship, dimensions, increased temperature, sustained pressure, burst pressure, and labeling are all covered, as well as requirements and test techniques for PE compounds. The final results of this method are displayed as per the international standards.

Overview
ASTM D2239 establishes specifications and test requirements for polyethylene (PE) plastic pipe manufactured with a controlled inside diameter (ID). Unlike outside-diameter-controlled pipe, ID-controlled pipe is designed for applications where the internal flow capacity is the primary engineering concern. The standard covers dimensions, pressure ratings, material requirements, and performance testing.
The inside diameter of the pipe is held to close tolerances to ensure consistent flow characteristics, while the wall thickness is adjusted based on the required hydrostatic pressure design basis and the standard dimension ratio (SDR). Testing includes burst pressure, sustained pressure, and quality conformance checks to ensure the pipe will perform reliably under service conditions.

Test Process
Dimensional Verification
Inside diameter, wall thickness, and length are measured to confirm conformance.
1Material Identification
Resin type and classification are verified against material specifications.
2Burst Pressure Test
Pipe is subjected to rapid pressurization to determine short-term burst strength.
3Sustained Pressure Test
Pipe specimens are held under elevated pressure for the required test duration.
