DESCRIPTION
This standard 20/30404851 DC BS ISO 10952. Glass-reinforced thermosetting plastics (GRP) pipes and fittings. Determination of the resistance to chemical attack for the inside of a section in a deflected condition is classified in these ICS categories:
  • 23.040.45 Plastics fittings
  • 23.040.20 Plastics pipes

This document specifies a method for determining the chemical resistance properties of glass-reinforced thermosetting plastics (GRP) pipes and fittings in a deflected condition for nominal sizes DN 100 and larger.

In conjunction with ISO 10928, this document provides a method for evaluating the effect of a chemical environment on the interior of a pipe or fitting after a specified period of time. Test conditions and requirements are specified in the referring International Standard. ISO 23856 references this document.

NOTE

It has been found that the effect of chemical environments can be accelerated by strain induced from deflection; hence, it is frequently referred to as strain corrosion.
