Railway applications - Braking - Automatic variable load sensing devices

inactive
Organization: NEN
Publication Date: 1 February 2019
Status: inactive
Page Count: 32
ICS Code (Materials and components for railway engineering): 45.040
scope:

This document applies variable load sensing devices designated to continuously sense the load of a railway vehicle and provide a signal that can be used by a relay valve for the automatic variation of the air pressure used for brake applications, thereby adjusting the brake force accordingly to achieve the required brake performance.

This document specifies the requirements for the design, dimensions, manufacture and testing of automatic variable load sensing devices.
