This standard, through re-drafting method, modifies and adopts ISO 4009.2000 “Commercial vehicles - Location of electrical and pneumatic connections between towing vehicles and trailers”. The technical differences between this standard and ISO 4009.2000 are as follows. - MODIFY the scope of application of the standard, including the central axis trailer train into the standard applicable range; - MODIFY the standard structure; ADD Chapter 3 Terms and definitions; SPLIT the Chapter 3 of international standard into Chapter 4, 5, 6, and 7; - MODIFY the size range presentation method in Figure 1, Figure 2, Figure 3, and Figure 4; - MODIFY the parameter descriptions of note b in Figure 1, Figure 2, and Figure 3; - MODIFY the installation location of the electrical and pneumatic connections relative to the vehicle driving direction in Figure 1, Figure 2, and Figure 3 (changed to the right side of vehicle); - SIMPLIFY the standard expression; DELETE the “ergonomics based” expression from Figure 1 and Figure 2; DELETE the expression of “the position and length of the helical pipeline is depending on the position of the connections” from 3.4.2.1 and 3.4.2.2; - DELETE the requirements for “quick connector” and “non-standard connector”; USE the pneumatic connector complying with SB/T 13881 standard, in order to improve the interchangeability of the pneumatic connector of towing vehicle and trailer. This standard also makes the following editorial changes. - MODIFY the name of the standard, in order to in line with the current similar standard name in China; CHANGE the “commercial vehicle” to “road vehicle”; - In the normative references, CHANGE all national standards adopting equivalently or through modification international standards into the corresponding national standards. Road vehicles - Location of electrical and pneumatic connections between towing vehicles and trailers1 ScopeThis standard specifies the installation position, size, clearance space, and the position of the helical pipeline connection, etc., for the electrical and pneumatic connections between the towing vehicle and trailer (abbreviated as electrical and pneumatic connection). This standard applies to the drawbar trailer, center-mounted axis trailers and articulated trains that are equipped with pneumatic brake systems, 24 V electrical equipment, AND rear positioned or front lower positioned drawbar coupling.2 Normative referencesThe following documents are essential to the application of this document.
