Specifies composition and test requirements. Appendices set out determination of melting point, weathering resistance, dispersion of pigment, resistance of pipe to internal pressure, chemicals, heat ageing and zinc chloride.

This Standard specifies requirements for polyamide 11 (PA 11) and 12 (PA 12) compounds suitable for making polyamide pipe and fittings for gas reticulation.NOTES:1. Advisory information on the determination of compliance of a lot with this Standard is given in Appendix A.2. This Standard does not preclude the use of these materials for other fluid distribution applications.
