Railway applications. Insulation coordination - Overvoltages and related protection Ingestion-build-512151 Scope This European Standard applies to: fixed installations (downstream of the secondary of the substation transformer) and rolling stock equipment linked to the contact line of one of the systems defined in EN 50163; rolling stock equipment linked to a train line. This European Standard gives simulation and or test requirements for protection against transient overvoltages of such equipment. Long term overvoltages are not addressed in this

Why should you use BS 1902-5

BS ISO 10263-5 specifies a test method to determine the performance of windscreen defrosting systems of earth-moving machinery

d)  the small ring shear procedure for drained residual shear strength parameters of remoulded clays

Such automation depends on the speed and accuracy of interpretation of mail item addresses by optical character recognition (OCR) equipment and/ or human operators (video-coders) working from video images of the mail items

to ensure that these requirements meet the key criteria of consistency and interoperability

and possible priorities are considered
