NSF/ANI Standard 14 requires materials for pressure pipe applications meet a minimum 50-year long-term strength requirement established through PPI's hydrostatic design stress.
The final two numerals in the term refer to the hydrostatic design stress (HDS) for that material in units of 100 psi with any decimal figures dropped.
