This British Standard specifies the dimensions required for correct mating of \u201ccontact\u201d type couplings for connecting the pneumatic braking system of towing vehicles to trailers or semi-trailers. If not specifically dimensioned, the couplings may follow a form to suit the manufacturer. This British Standard also specifies performance requirements for the couplings, identity markings, serviceability, inspections, and maintenance.<\/p>\n

The layout and position of the couplings on the vehicle are defined in BS AU 195a:1991 and are not incorporated in this revised British Standard.<\/p>\n

Rubber hose assemblies are specified in BS AU 110a:1995 and are not incorporated in this revised British Standard.<\/p>\n

Coiled pipe assemblies are specified in ISO 7375-1:1996, ISO 7375-2:1998, ISO 7628-1:1998, and ISO 7628-2:1998, and are not incorporated in this revised British Standard.<\/p>\n

This British Standard applies to two-line pneumatic braking systems and to three line pneumatic braking systems that include a secondary line.<\/p>\n

This British Standard specifies C type and CA type \u201ccontact\u201d couplings. C type couplings are used in two line braking systems, and the CA type exclusively for the secondary line of a three line braking system. Each of the assemblies specified in this British Standard are intentionally physically non-interchangeable. It is further intended that each of the assemblies cannot be dismantled or repaired. This British Standard specifies the following:<\/p>\n

    \n
  1. the form and dimensions of the mating parts of the C type \u201ccontact\u201d coupling and for the self-sealing valve and valve lifter to be incorporated in the coupling, to enable it to be used on the control or on the supply line of a two-line or three-line pneumatic braking system;<\/li>\n
  2. the form and dimensions of the mating parts of the CA type \u201ccontact\u201d coupling and for the self-sealing valve incorporated into the female coupling, to enable it to be used on the secondary line of a three-line pneumatic braking system.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
