Provides manufacturers, designers and purchasers of cement-mortar-lined steel pipes and fittings with a specification for their design and manufacture. This Standard applies to pipes of diameter 100mm or larger, for the conveyance of water intended for human consumption or for the conveyance of wastewater or process water. Guidelines on information to be supplied by the purchaser to the manufacturer and variations that should be agreed upon at the time of inquiry or order are provided. Methods for demonstrating compliance with this Standard are also provided.

This Standard specifies requirements for the cement mortar lining of steel pipes and fittings of 100 mm diameter and greater, by centrifugal, spray or hand application methods, prior to their installation in pipelines. These pipelines are used for the conveyance of water intended for human consumption or for the conveyance of wastewater or process water.NOTES: 1 Guidelines to purchasers on information that should be supplied by the purchaser and those variables that should or may be agreed upon at the time of enquiry or order are given in Appendix A.2 Alternative methods for demonstrating compliance with this Standard are given in Appendix B.
