5.3 Coil dimensions
Dimensions of the coiled connecting cables shall be as detailed in Table 2 and Figures 1 and 2.
L B = Block length or Retracted length
This is the length of the coiled part of the spiral excluding straight tails, in its unstretched state.
L W = Working length
This is the total length of the coiled connecting cable including straight tails, when it is connected between the towing and towed vehicle without any articulation.
L Emax. = max. admitted extension length
Maximum length of the coiled connecting cable including straight tails, at which the cable still function according to the requirements.
NOTE This normally occurs when the cable is connected between the towing and towed vehicle when the vehicle is fully articulated.BS ISO 4141-3 pdf download.
