Specifies requirements for materials for loose polyethylene sleeving intended for the corrosion protection of ductile and grey iron pipelines when installed underground.

This Standard specifies requirements for materials for loose polyethylene sleeving intended for the corrosion protection of ductile and grey iron pipelines when installed underground.NOTES:1. Guidelines for the application of polyethylene sleeving to ductile iron pipelines and fittings are given in AS 3681.2. Guidelines for purchasing polyethylene sleeving are given in Appendix E.
