Discover Element’s Leading Hydrostatic Pressure Test Service

51³Ô¹ÏÍøprovides an extensive capacity for determining the long-term hydrostatic strength of plastic pipes, offering a comprehensive suite of services from initial testing to regression analysis. Our focus is on delivering reliable and reproducible test data for the classification of Minimum Required Strength (MRS) to ISO 9080 and Hydrostatic Design Basis (HDB) services to ASTM D2837 and ASTM D2992.

As part of Element's global Plastic Pipes & Fittings Testing program, our hydrostatic pressure testing services cater to resin manufacturers, pipe extruders, certification bodies, and utility companies worldwide. We understand the critical need for independent and accurate test data for product classification and lifetime evaluation in the industrial sector.

Testing to ISO 9080 (MRS) and ASTM D2837 (HDB) involves a comprehensive evaluation process. It includes hydrostatic pressure testing to generate test data, followed by regression analysis to determine long-term hydrostatic strength. The final step involves the classification of Hydrostatic Design Basis (HDB) or Minimum Required Strength (MRS).

Advanced Hydrostatic Pressure Testing Service

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.
