This document specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on polysulfone (PSU) injection moulded fittings. This document is applicable for polysulfone homopolymer compounds only.
Abstract
Overview
ISO 4075:2025 - Polysulfone (PSU) - Effect of time and temperature on expected strength specifies minimum expected-strength reference lines for used in injection‑moulded fittings. The standard defines how hoop stress, time and temperature interact to predict long‑term hydrostatic strength for design calculations and conformity assessment of PSU components used in piping systems.
