标准范围
This document specifies methodologies for calculation of braking performance for railway rolling stock
and is applicable to all countries.
This document describes the general algorithms/formulae using mean value inputs to perform
calculations of brake equipment and braking performance in terms of stopping/slowing distances,
stationary braking, power and energy for all types of rolling stock, either as single vehicles or train
formations, with respect to the braking distance.
The calculations can be used at any stage of the assessment process (design, manufacture, testing,
verification, investigation, etc.) of railway rolling stock. This document does not set out the specific
acceptance criteria (pass/fail).
This document is not intended to be used as a design guide for selection of brake systems and does
not specify performance requirements. This document does not provide a method to calculate the
extension of stopping distances when the level of available adhesion is exceeded (wheel slide activity).
This document contains examples of the calculation of brake forces for different brake equipment types
and calculation of stopping distance and stationary braking relevant to a single vehicle or a train.
