ISO 10952:1999 Plastics piping systems - Glass-reinforced thermosetting plastics (GRP) pipes and fittings - Determination of the resistance to chemical attack from the inside of a section in a deflected condition
This standard 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 standard 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.
This method shall also be used as the basis for conducting tests according to so called "specified levels" as allowed by referencing system standards. The specified level approach does not involve extrapolation of test data.
NOTE 1: It has been found that the effect of chemical environments can be accelerated using strain induced by deflection, hence it is frequently referred to as strain corrosion.
