BS ISO 3584-2020 Road vehicles一Clevis couplings一 Interchangeability. This document specifies the characteristics necessary for the mounting and interchangeability of clevis couplings on the frame (cross member, drawbeam or mounting bracket) of towing vehicles for trailers. This document is applicable to clevis couplings intended for connection to trailers equipped with a drawbar eye on the drawbar of the trailer. Characteristics not specified are left to the discretion of the component manufacturer. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
