Abstract

Specifies constructional requirements for water containers (shells) made of single materials, viz. plastics, copper or copper alloys, or stainless steel. Gives recommendations on maximum water temperature and specifies routine and type test schedules.

Scope

This standard specifies requirements for water heaters with single shells made from the following:
(a) Plastics (for operation at a head not greater than 2 mH2O).
(b) Non-ferrous metal.
(c) Stainless steel.
