VDA 5 Practical Guide

Measurement and testing processes, suitability, planning and management Practical guide 

The present VDA 5 Practical Guide has been prepared as a supplement to the new VDA Volume 5, 3rd edition 2021. In order to comprehend the contents of this practical guide, it is essential to be familiar with VDA Volume 5, in which the methodology and approach are described in detail. We made a conscious decision not to cover the theoretical background again in the VDA 5 Practical Guide. Instead, this guide serves to illustrate ways to apply the theory in everyday situations at work, specifically with regard to measurement and inspection process capability.

Table of contents:
1 Risk-based assurance
1.1 Use of a caliper gauge without determination of product information
1.2 Inspecting the pre-adjustment of components and ascertaining the delivery quality by means of a downstream inspection process (EOL)
1.3 Inspection of the flushness of roof shells on a retractable hardtop – end-of-line test (EOL) at the supplier’s premises
1.4 Examining the differences between motorbikes and passenger cars regarding the consideration of the specific application
2 Typical applications
2.1 Manual measurement of bore diameters
2.2 Piston guide ring with automated measuring device
2.3 Optimization of a measurement process
2.4 Measurement process capability of a multi-point measuring device based on the example of a measuring machine with double station
