This document defines a harmonized way to assess the braking performance by test of locomotives, passenger coaches, freight wagons, railbound construction and maintenance machines, and self-propelled passenger trains (multiple units) including high speed trains. The document sets out the standardized method for undertaking brake performance tests and the correction factors to be applied to the data obtained for all types of rolling stock. This document also defines the methods to assess the brake performance in terms of stopping distance, and from this the process to determine vehicle(s) deceleration and braked weight. It then deals with conversion of the braked weight to the braked weight percentage of a vehicle or train for operating purposes. It also sets out additional factors when determining the braked weight percentage of a train calculated from specified braked weight, depending on the formation of the train. In Annex D there is a method for determining brake performance of freight wagons fitted with P10 cast iron or LL-blocks using limited testing (force measurement).

This document specifies the requirements for closing and locking devices of heavy rail freight wagons including durability, their status indication, maintenance and recycling. Annex A specifies pass-fail criteria for the dimensioning tests. This document is not applicable to closing and locking devices which are used to ensure a pressure difference or to retain liquids/liquid payloads. This document is not applicable to heavy rail freight wagons which are emptied by pressure, nor is it applicable to lose tarpaulins.
