The hoses and hose assemblies specified in this International Standard are intended for use "wet", i.e. permanently flled with liquid, in the temperature range from - 40 C to + 60 ℃. The maximum working pressure is 20 bar (2 MPa) 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
