BS EN 1393:1997- Plastics piping systems. Glass-reinforced thermosetting plastics (GRP) pipes. Determination of initial longitudinal tensile properties

This standard specifies three test methods for determining the longitudinal tensile properties of pipes of glass-reinforced thermosetting plastics (GRP). The properties which can be determined are: - the longitudinal tensile strength; - the percentage ultimate elongation; - the longitudinal modulus of elasticity. Method A uses for the test piece(s) a longitudinal strip cut from a pipe. Method B uses a specified length of the full cross section of the pipe. Method C uses a notched plate cut from a pipe wall section.
