scope:

This document covers the testing for acceptance of the running safety of freight wagons with side buffers and screw couplers at their ends under longitudinal compressive forces.
This document applies to the following types of freight wagons:
. Wagons equipped with side buffers and screw couplers at their ends;
. Permanently coupled units with side buffers and screw couplers at their ends and between the vehicles;
. Permanently coupled units with side buffers and screw couplers at their ends and diagonal buffers with screw couplers between the vehicles;
. Articulated wagons with three 2-axle bogies equipped with side buffers and screw couplers at their ends;
. Low-floor wagons with eight or more axles (e.g. Rolling Road wagon).
NOTE A description of such vehicles is given in UIC 571-4:2004, 3.4.
The following vehicles are not currently in the scope of this document:
. Wagons with automatic couplers;
NOTE These wagons are handled in UIC 530-2.
. Wagons with 3-axle bogies;
NOTE Due to their high tare mass and their short length these wagons were not specially investigated according to this standard in the past, because it was anticipated, that these wagons can safely sustain higher longitudinal compressive forces than other wagons.
. Permanently coupled units with a bar coupler between the vehicles;
NOTE A working group of UIC is developing the acceptance conditions for this type of wagon. It is planned to include the regulations into this European Standard.
. Articulated wagons with more than three two axled bogies.
Acceptance criteria and test conditions as well as conditions for the dispensation of tests are defined in this document.
This document applies principally to all wagons which operate without restriction on standard gauge tracks (1 435 mm). The working group is not aware of the influence on railway systems using different gauges.
The described criteria are part of the type testing of wagons which are newly developed or have had relevant design modifications. The testing and acceptance refers to the complete vehicle including the running gear.
