Specifies requirements for coating for protection against corrosion, where the coating is not subject to weather exposure (a safe period of 18 months of weather exposure is allowed for to cover an extended storage period prior to installation), and the pipeline operating temperatures are not above 60°C nor below -40°C. Coating thickness for normal and heavy duty for a given range of nominal pipe sizes are tabulated.

Scope

This Standard specifies requirements for fusion-bonded low-density polyethylene coating of pipes and fittings for protection against corrosion. The coating is intended for use on pipes and fittings that are installed in locations not subject to weather exposure, although a safe period of 18 months of weather exposure is allowed for to cover the storage period prior to installation.
NOTES:
1 Advisory information on methods of determining compliance of a 'lot' with this Standard is given in Appendix A.
2 Guidelines to purchasers on requirements that are to be specified by the purchaser and those that are to be or may be agreed upon at the time of enquiry or order are given in Appendix B.
3 The attention of purchasers is drawn to the necessity to ascertain the expected weathering period of the coating before installation, and in the likelihood of 18 months being exceeded, to make provision for shielding of the coating from direct sunlight.
Polyethylene materials complying with this Standard are intended for application to pipes and fittings where the pipeline operating temperatures are not normally more than 60°C nor less than -40°C.
