AS/NZS 4766
The Standard
AS/NZS4766 is a standard for storage tanks for water and chemicals. It applies
specifically to tanks rotationally moulded from polyethylene and addresses the suitability and quality
of raw materials used as well as defining design requirements for tanks and procedures for ensuring proper
workmanship in producing them. The most recent version of the standard is AS/NZS 4766:2006.
Compliance and Certification
Raw materials and tanks that fulfil all requirements specified in AS/NZS4766 are compliant with the standard.
Any manufacturer can claim compliance of their product with the standard. It is up to them to ensure that all
requirements are met and the relevant documentation is available since there is no independent verification of
the claim.
A manufacturer can also opt for certification of their product through an accredited organisation. This means
that an independent auditor will regularly verify the claim of compliance with the standard by ensuring all the required
documentation is available and that the procedures that ensure quality and workmanship of the tanks are followed.
There is no separate standard for the raw material used in producing tanks. Therefore, technically, the powder cannot be
certified to AS4766. However, a number of certifying organisations will issue type test certificates as a means to prove
that the compliance of the material with all relevant sections of the standard has been independently verified.
