This standard describes methodologies for calculation of braking performance for railway rolling stock and is applicable to all countries. This standard is published in two separate parts (ISO 20138-1 and ISO 20138-2) which will complement each other and can be used separately dependent on the requirements of the user. ISO 20138-1 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. ISO 20138-2 2) details the step by step calculation methodology utilizing instantaneous values of brake force provided by each operational brake equipment type throughout the stopping/slowing time. The calculations can be used at any stage of the assessment process (design, manufacture, testing, verification, investigation etc.) of railway rolling stock. This standard does not set out the specific acceptance criteria (pass/fail). This standard is not intended to be used as a design guide for selection of brake systems and does not specify performance requirements. This standard does not provide a method to calculate the extension of stopping distances when the level of available adhesion is exceeded (wheel slide activity). This standard 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.
