29、d for hose assemblies, that is, hoses with couplings already fitted, where this iscarried out by the hose manufacturer (see clause 8).Type A (Rubber) hoses are intended for use at a minimum temperature of -20 G01C and Type B (Thermoplastics)hoses are intended for use at a minimum temperature of -10
30、G01C.NOTE 2 Hoses for use at temperatures lower than those specified above can be supplied by agreement between themanufacturer and purchaser. In this case, the low temperature flexibility test (see 6.3) should be carried out at the specifiedtemperature.2 Normative referencesThis European Standard i

36、nd definitions for working pressure, proof pressure andburst pressure given in ISO 8330 apply.4 Classification4.1 Type (hose construction)Type A hoses shall consist of:a) a rubber lining uniform in thickness, reasonably concentric and free from holes, porosity and other defects;b) a textile reinforc
37、ement applied uniformly by any suitable method;c) an embedded wire helix or helices evenly and uniformly applied and made from metallic material that allowsthe hose to meet the specification requirements;d) a rubber cover, ozone resistant, uniform in quality and thickness and free from defects.Type
38、B hoses shall consist of a flexible, thermoplastics material supported in its mass by a helix of rigid polymericmaterial. The reinforcement and flexible components of the hose wall shall be fixed and free from cracks, porosity,foreign inclusions or other defects.4.2 Hose endsThe hose ends shall be c
39、ompatible with suction hose couplings conforming to the relevant national standards.NOTE Where soft ends or wire-free ends are used for type A hoses, they should have an additional rubberized textilereinforcement applied as a cuff over the wire-free portion and the first turn of the embedded wire he
40、lix.The hose ends should be capped or sealed to prevent ingress of water.Specifying the dimensions of the soft or wire-free ends may be the subject of an agreement between themanufacturer and the purchaser.5 Dimensions, tolerances and maximum mass5.1 Inside diameter and maximum massThe dimensions of
41、 the hose and tolerances, when measured in accordance with ISO 4671, shall conform to therequirements given in Table 1.
