Abstract

Specifies requirements for factory-applied fusion-bonded medium-density polyethylene coatings for pipes and fittings, for protection against corrosion at operating temperatures between -40C and plus 50C. It is intended for use by specifiers, applicators, manufacturers and purchasers of steel water pipeline.

RECONFIRMATION NOTICE
Major stakeholders of this publication have reviewed the content of this publication and in accordance with Standards Australia procedures for reconfirmation, it has been determined that the publication is still valid and does not require change.
Certain documents referenced in the publication may have been amended since the original date of publication. Users are advised to ensure that they are using the latest versions of such documents as appropriate, unless advised otherwise in this Reconfirmation Notice.
Approved for reconfirmation in accordance with Standards Australia procedures for reconfirmation on 27 December 2018.

Scope

This Standard specifies requirements for factory-applied fusion-bonded medium-density polyethylene coating and lining of pipes and fittings, for protection against corrosion. Polyethylene materials complying with this Standard are intended for application to pipes and fittings where the pipeline operating temperatures are not less than -40C nor more than 70C for the coating and 50C for the lining.
The coating is intended for use on pipes and fittings for underground and underwater service, including steel piling. The lining is intended for use on pipes and fittings for pipelines conveying wastewater and water intended for human consumption.
Methods for determining compliance with this Standard are given in Appendix A.
NOTE: Guidelines on requirements that are to be specified by the purchaser at the time of enquiry or order are given in Appendix B.
