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.

Note A conservative approach has been taken by basing the analysis on the activation energy for polyolefins, 110 kJ/mol, for Hot and Cold-water applications. If experimental evidence can be given that other extrapolation time factors are justified, these may be used instead of the factors given in Table 1 of ISO 9080:2012.
