This part of ISO 5692 specifies the requirements for vehicle coupling rings with a ring inside diameter of for

coupling with the drawbar coupling specified in ISO 6489-2, and for ensuring vehicle coupling with the necessary

horizontal and vertical rotation angle.

This part of ISO 5692 is applicable to couplings where the vertical static load is not more than and the

dynamic horizontal load is not more than the value of .

NOTE For value , see ISO 6489-2.
