Full Description

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 IS0 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.
