scope:

The document covers the following areas of testing and V&V: -

• Data testing

• Factory Acceptance testing

• System Integration and test

• Site testing

• Commissioning testing

• V&V management

• Competence and independence

• Documentation

The document excludes the following areas which may be related to V&V processes but will be specified separately in supporting documentation: -

• Installation processes and techniques (App. L)

• System handback (App. M)

Purpose

This document is an appendix to the Modular Signalling Handbook and defines the principles and processes for testing and Verification and Validation (V&V) that should be applied to Modular Signalling Schemes.

This document does not replace the Network Rail Signal Works Testing Handbook except where specific derogations are detailed elsewhere in the Modular Signalling Handbook. Rather, this document describes opportunities for efficiency within the constraints of that document and is to be considered 'best practice' for Modular Signalling schemes.
