ASTM D2241 Hydrostatic Pressure Test Burst pressure testing machine for PVC Pressure-Rated Plastic Pipe specification covers poly(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water. Poly(vinyl chloride) plastics used to make pipe meeting the requirements of this specification are categorized in two criteria: short-term strength tests, and long-term strength tests. The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. The material shall conform to the required wall thickness, sustained pressure, burst pressure, flattening, extrusion quality, and impact resistance. It shall be subject to an accelerated regression test.
Advanced Hydrostatic Pressure Testing Service
ISO 9080 (MRS) Testing
Objective: Determine Minimum Required Strength (MRS) based on long-term hydrostatic strength at 20°C and 50 years.
Process: Rigorous hydrostatic pressure testing and regression analysis for precise classification of plastic pipes to ISO 9080 standards.
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.
ASTM D2837 / (HDB) Testing
Objective: Classify based on Hydrostatic Design Basis (HDB) using long-term hydrostatic strength at 73°F (23°C) and 100,000 hours.
Process: Hydrostatic pressure testing and regression analysis for compliance with ASTM D2837 and PPI TR-3 standards.
