Abstract

This Standard specifies requirements for the suitability of products for use in contact with drinking water, with regard to their effect on the quality of water.

Scope

This Standard specifies requirements for the suitability of products for use in contact with drinking water, with regard to their effect on the quality of water. These products include pipes, fittings, components, and materials used in coating, protection, lining, jointing, sealing and lubrication applications in the water supply and plumbing industry. The Standard requires that products intended for use in contact with drinking water be tested by exposure to test water. Where appropriate, a scaling factor is applied to such tests to compensate for differences between laboratory and field conditions.
NOTE: This Standard may be used to test the suitability of products intended for use in contact with types of water other than drinking water.
This Standard does not take into account possible changes in installation practices or environmental factors not directly associated with the product. As a guide, re-verification testing of products to this Standard is desirable after a period of five years.
NOTES:
1 Products captured by the Plumbing Code of Australia (PCA) or by other regulatory requirements may have specific reverification testing requirements, but they are beyond the scope of this Standard.
2 For products that are not captured by the PCA, guidance on when reverification testing is required due to a formulation change is provided in Appendix O.
3 Chemicals used directly for treating raw water to provide a suitable drinking water supply are not covered by this Standard.
4 Guidelines for applying and interpreting this Standard are provided in Appendix R.
