Railway applications - Measurement of vertical forces on wheels and wheelsets - Part 3: Approval and verification of on track measurement sites for vehicles in service

Scope

This document is related to EN 15654‑1, Railway applications — Measurement of vertical forces on wheels and wheelsets - Part 1: On-track measurement sites for vehicles in service, which lays down minimum technical requirements and the metrological characteristics of a system for measuring and evaluating a range of vehicle loading parameters during operation in service.

The aim of this document is to describe approval and verification procedures to validate the functional and metrological characteristics of measurement systems and confirm them over time.

The goal is to obtain the comparability and reproducibility of measurement results under different boundary conditions. To minimize the number of tests, the approval and verification procedures are divided into:

— type approval

— initial verification,

— in-service verification.
