11、ber bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmen
12、tal and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Direc
13、tives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodi

The following preconditioning shall be performed prior to testing: a) conditioning for 2 h at a temperature of ( 40 2) C, one extension once to its maximum admitted extension length
27、 in accordance with ISO 4141-3 within 15 s after being removed from the temperature chamber, and subsequently resting for 120 s in restored conditions at room temperature; b) the same as in step a), but conditioning for 2 h at (80 2) C; c) cooling down at room temperature for another 2 h. 4 Articula
28、tion test 4.1 Purpose The purpose of the articulation test is to specify the strength of the complete plug and cable assembly and the effect of anti-kink protection against bending, in order to replicate extreme angles occurring between vehicle and trailer whilst manoeuvring. 4.2 Test method Both pl
29、ugs shall be inserted in sockets in a test arrangement in accordance with Figure 1. The fixing of at least one socket shall permit rotation around axis A. Conductor breakage shall be monitored by applying a current of (5 0,5) A to all pins and connected conductors of the coiled assembly during the e
30、ntire test phase (see Figure B.2). Conductor breakage occurs if the applied current drops by more than 1,0 A for more than 10 ms. In such cases, the test procedure shall stop automatically. 4.3 Test description One of the connectors shall be articulated 90 each way to the longitudinal axis of the cl
31、osed coil. Rotate the connector around axis A. The test shall be carried out at a frequency of 15 cycles per minute and shall comprise the following steps: a) position 1 functionally important datum plane; b) rotation around axis A by 180 to position 2; c) rotation back to position 1 completes the c
32、ycle; d) check fulfilment of the requirements in 4.4; e) perform steps a) to d) with the opposite cable assembly side. NOTE If both connectors are tested simultaneously, step e) can be omitted.

Apply a test voltage of 1 kV RMS, 50 Hz or 60 Hz, or 1 600 V d.c. for 1 min between each conductor and the remaining conductors connected together. Breakdown shall not occur. 5 Torsion strain (mecha
36、nical strength of plug/cable assembly) 5.1 Purpose The purpose of the torsion strain test is to specify the strength of the complete plug and cable assembly against torsion occurring due to rotated connection. 5.2 Test method At least one plug shall be inserted in a socket in a test arrangement in a
37、ccordance with Figure 2 or Figure 3. The fixing of the cable at the fasten point shall permit rotation around the longitudinal axis. The cable shall be fastened in accordance with Figure 2 or Figure 3. Conductor breakage shall be monitored by applying a current of (5 0,5) A to all pins and connected
38、 conductors of the coiled assembly during the entire test phase (see Figure B.2). Conductor breakage occurs if the applied current drops by more than 1,0 A for more than 10 ms. In such cases, the test procedure shall be stopped. 5.3 Test description Fasten down the cable as shown in Figure 2 or Figu
39、re 3. Rotate the cable around the rotating axis B with a maximum torque of 20 Nm up to 360 or stop rotation at the required value, whichever occurs first, denoted by end position. Perform the test in each rotational direction at a speed of 15 5 per second. One test cycle shall comprise the following
40、 steps: a) position 1 datum: apply one mark between the cable, its anti-kink protection (if any) and the connector; b) rotate the cable at the fasten point clockwise around the longitudinal axis; c) check fulfilment of the requirements in 5.4.2; d) rotate the cable at the fasten point back to datum
41、position; e) rotate the cable at the fasten point as described in step b), but anti-clockwise; f) check fulfilment of the requirements in 5.4.2; g) rotate the cable at the fasten point back to datum position; h) perform steps a) to g) with the opposite cable assembly side. NOTE If both ends are test
42、ed simultaneously, step h) can be omitted.
