Custom Testing and R&D Lab Services
We utilize standard pressure testing methodologies to determine a material’s hydrostatic design basis (HDB) and hydrostatic design stress (HDS). These test methods allow NSF to forecast the long-term material strength to help ensure safe use in the field.
HDB: The categorized long-term hydrostatic strength (LTHS) in the circumferential or hoop direction, for a given set of end use conditions as established by ASTM D2837.
HDS: The recommended maximum hoop stress that can be applied continuously with a high degree of certainty that pipe failure will not occur.
