Railway applications - Railway rolling stock - Buffers
This document defines the requirements for buffers with 105 mm, 110 mm and 150 mm stroke for vehicles or units which use buffers and screw coupling. It covers the functionality, interfaces and testing procedures, including pass fail criteria, for buffers. NOTE 1 Typically, buffers with a stroke of 105 mm are used on freight wagons and locomotives, buffers with a stroke of 110 mm are used on coaches and locomotives and buffers with a stroke of 150 mm are used on freight wagons. It defines the different categories of buffers, the space envelope, static and dynamic characteristics and energy absorption. It defines the static and dynamic characteristics of the elastic systems. It also defines the requirements for buffers with integrated crash elements (crashworthy buffers) for tank wagons for dangerous goods. The requirements of this document also apply to buffers of locomotives and passenger coaches which are bound to meet the crashworthiness requirements of EN 15227 for normal service only. The properties for the energy absorbing function are defined in EN 15227 and the requirem
