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.

 

This document specifies a method to determine the sensitivity of a textile floor covering for appearance change after water has been spilled and dried on the surface. This change can be: a) a colour change; b) a change in structure; c) migration and concentration of chemicals coming from the product. NOTE A concentration of chemicals on a part of the surface can cause accelerated uneven soiling of textile floor coverings.
