NR NR/L2/SIG/30014/A310 ISSUE 1 PDF

This level 2 standard applies to testing of signalling equipment associated with Modular S&C installations.

Modular Signalling testing requirements are detailed in NR/L2/SIG/30097, and that standard shall take precedence over this standard with respect to Modular Signalling Projects. However, where NR/L2/SIG/30097 is silent on any aspect of signalling works testing, this standard shall apply instead.

Manufacturer's product testing is the quality assurance testing in the factory of discrete off the shelf products or equipment. This testing would be carried out to standard drawings in accordance with manufacturer's Quality System, and is certified by the issue of Certificates of Conformance. Manufacturer's product testing is outside the scope of signalling works testing, and is considered to be part of the supply chain quality management system. Where this type of testing is used for equipment provided as part of the Modular S&C systems, the product or equipment shall be supplied with a Certificate of Conformance and form part of the Chain of Custody

Off Site Testing comprises any testing of bespoke, uniquely wired equipment, bespoke systems, data or software – but may involve products already Quality assured by the manufacturer - that is carried out before such equipment, systems, data or software is installed on site in its final configuration. Off-site testing of signalling equipment associated with Modular S&C installations is within the scope of signalling works testing, and shall be carried out in accordance with the requirements of this standard.

Where there is a conflict between the processes and requirements shown in this standard and NR/L3/SIG/30071, this standard shall take precedence. Similarly, where this specification is silent, the requirements of NR/L3/SIG/30071 shall be followed.

Where neither this specification nor standard NR/L3/SIG/30071 contains a requirement, NR/L2/SIG/30014/A110 shall be followed.

Purpose

This document is part of the suite of documents relating to the Modular Switch and Crossing activities and contains the process for testing and commissioning signalling equipment associated with new S&C layouts that have been designated as Modular at the inception stage of the End to End process.

This Level 2 document sets out the mandatory procedures and process controls necessary to confirm that new signalling associated with Modular S&C installations, and alterations to existing installations, are independently tested in a manner that assures:

• Compliance with the Project specifications and Design Details; and,

• Fitness for purpose before they are offered for Entry into Operational Service.

It also provides a framework of procedures and process controls that are, as far as practicable, consistent across the Network Rail infrastructure for this type of work.
