The length o
39、f the assembled pneumatic half coupling, dimension X-X in Figure 5 or 7, is specified to suit the application, but the recommended length is 730 mm. The nipple to connect to the end cock shall be as shown in Figure 1 (and is the same as for the air brake pipe) and have a truncated internal ISO 228 -

The length of the flexible hose is varied to suit the application, but should be the standard 620 mm to give the
41、recommended length of 730 mm for dimension X-X as shown in Figures 1, 5 and 7. The recommended length of these hoses when used with a swing head autocoupler should be increased to give an assembled length of the pneumatic half coupling of 1 080 mm for the automatic air brake pipe and 930 mm for the
42、main reservoir pipe. Elastomeric composite hoses having a textile reinforcing inlay sealed (vulcanised) at each end shall generally be used for these couplings, Figure 9, but hoses of other materials, e.g. metallic, may be used if they are flexible enough. The flexible hose shall conform to the dime
43、nsions defined in Figure 9. The choice of elastomers for elastomeric composite hoses is the choice of a manufacturer to meet the requirements of this specification. The elastomer used during a serial production shall conform with regard to the formulation of materials and characteristics to those pr
44、oducts tested in the qualification procedure. The tolerances for the overall length of the pneumatic half couplings shall be: 6 000 mm 0,8 % The requirements 4.1.3.2 to 4.1.3.14 concern the elastomeric composite hoses. NOTE In the case of use of another material, the tests to be conducted shall be d
