Text prepared by the informal group on Regulation No. 55 to amend the requirements for movable couplings, increase the range of application of remote controls to couplings similar to C50-X and G50-X, enable the increase of characteristic values of standard couplings and to add requirements for the mounting of couplings.

Corrections to delete text concerning movable couplings that was inadvertently included in document GRRF/2013/16.
