We offer extensive capacity for determination of long-term hydrostatic strength for plastic pipes, from initial testing to regression analysis for determination of hydrostatic strength and classification of Minimum Required Strength (MRS) to ISO 9080 and Hydrostatic Design Basis (HDB) services to ASTM D2837 and ASTM D2992.
Hydrostatic pressure testing is part of Elements global Plastic Pipes & Fittings Testing program, provided to resin manufacturers, pipe extruders, certification bodies and utility companies worldwide, where independent, reliable and reproducible test data is required for product classification and life time evaluation.
Testing to ISO 9080 (MRS) and ASTM D2837 (HDB)
A complete evaluation includes hydrostatic pressure testing for generation of test data followed by regression analysis for determination of the long term hydrostatic strength, and finally classification of HDB (Hydrostatic Design Basis) or MRS (Minimum Required Strength).
- MRS classification to ISO 9080 is based on the long-term hydrostatic strength at 20°C and 50 years.
- HDB classification to ASTM D2837 / PPI TR-3 is based on the long-term hydrostatic strength at 73°F (23°C) and 100,000 hours.
Standard test conditions
For cold water and gas pipe materials the common test temperatures are 20°C, 60°C and 80°C. For hot water materials 20°C, 70°C, 95°C and 110°C are normally used. For ASTM standards Fahrenheit temperatures are used.
High precision pipe sample measurement
High precision measurements of all critical dimensions of the test samples are carried out by a robot cell. Finding the minimum wall thickness is critical to minimize scatter in pressure testing results. Our automated measuring process by computed radiography is helping to make certain we cover the whole pipe wall. The procedure is ideal for automation of the repetitive work where high precision is required.
