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 polyphenylsulfone (PPSU) injection moulded fittings.
Abstract
Overview
ISO 4076:2025 - Polyphenylsulfone (PPSU) - specifies minimum expected strength (hoop stress) for injection‑moulded PPSU fittings as a function of . It defines generic (mathematical curves) for long‑term hydrostatic strength to be used in design calculations, establishes extrapolation limits for life‑time predictions, and gives procedures to demonstrate conformance. The reference lines are intended as generic guidance (not grade‑ or supplier‑specific).
