Draft Designation: DR AS/NZS 2845.3:2018The objective of this Standard is to outline minimum requirements for the testing and maintenance of testable backflow prevention devices in the field.
This Standard is to be read in conjunction with the requirements of the relevant regulatory authority, and the manufacturer’s instructions. The safety practices to be followed while performing field testing and maintenance work should comply with the applicable WH&S legislation and the relevant regulatory authority’s procedures. The actions stipulated within this Standard are in addition to those requirements.
The terms “normative” and “informative” are used in Standards to define the application of the appendices to which they apply. A “normative” appendix is an integral part of a Standard, whereas an “informative” appendix is only for information and guidance.
