Specifies range of nominal sizes (DN 100 to DN 1000), crushing strength classes (3 and 4), dimensional and performance requirements for vitrified clay pipes and fittings and flexible joints (socket and sleeve types), for operation under gravity, intended for the conveyance of sewage and industrial waste. Appendices set out test procedures, dimensions and tolerances for pipes, common fittings and socket type flexible joints, purchasing guidelines and methods for determination of compliance with this Standard.

This Standard specifies requirements for vitrified clay pipes and fittings with flexible joints, for operation under gravity, intended for the conveyance of sewage and industrial waste.NOTES:1 Appendix A sets out guidelines on the information to be provided by the purchaser at the time of enquiry or order.2 Methods for determining compliance with this Standard are given in Appendix B.
