AS 3498:2003 PDF Download

AS 3498:2003 is a standard that outlines authorization requirements for plumbing products such as water heaters and hot-water storage tanks. The standard specifies basic safety and public health requirements that must be met to ensure connection to a potable water supply. The standard applies to different types of water heaters that use different heating methods, including electric resistance, gas, liquid or solid fuels, waste-heat recovery systems, solar energy, or any other means of heating potable water.

This standard does not include requirements affecting the durability of water heaters, except those applying to safety devices. It also excludes steam generators, sterilizers, washing machines, wash boilers, urns, kettles, or hot-water supply systems intended solely for space heating, swimming pools, spa pools, or industrial processes. The installation of water heaters and hot-water supply systems is covered by other applicable standards, namely AS 3500.4.1, AS/NZS 3500.4.2, and AS/NZS 3500.5.

It is important to note that additional requirements may be applicable to early childhood centers, primary and secondary schools, nursing homes, or similar facilities for young, aged, sick, or disabled persons. This is described in AS/NZS 3500.4.2.
