This document specifies requirements for hoses and hose assemblies made of rubber and hose fittings made of metal, which are designed to convey saturated steam and hot water condensate.
This document applies to the following two types of hoses and hose assemblies:
—     low pressure, with a maximum working pressure of 0,6 MPa (6 bar)
—     high pressure, with a maximum working pressure of 1,8 MPa (18 bar).
Each type is divided into two classes, having either an oil resistant or non-oil resistant cover.
