NR NR/L2/RSE/100/05 ISSUE 4 PDF

This module mandates the process for gaining acceptance of:

a) a new or modified controlled product that, where relevantaligns with the Network Rail challenge statements, that has been evaluatedagainst the Rail Industry Readiness Levels (RIRLs) where;

   • technologyreadiness level (TRL) 6 is completed

   • ReliabilityReadiness Levels (RRL) 7 is completed as outlined in NR/L2/RSE/0005,

 b) a change of application of a controlled product;

 c) a change of manufacturer of a controlled product;

 d) a change of operational environment for a controlled product;

 e) a compatibility issue for Network Rail’s infrastructurepotentially caused by installation of a product not owned by Network Rail onthe infrastructure.

 f) equipment that is used on or near the line or as deemednecessary by the Network Technical Head for the affected discipline.

 NOTE 1 Information on RIRLs (along with how TRLs & RRLsalign with these) can be found in Appendix A

 NOTE 2 NR/L2/RSE/0005 provides guidance on the Design forReliability Process and RRLs.

 NOTE 3 The Common Safety Method Risk Evaluation and Analysis(CSM RA) process is conducted throughout the product development as per moduleNR/L2/RSE/100/02.

 NOTE 4 Research and Development products are assessed by tothe Product Development Framework panel to determine whether there is a requirementto progress as per the stage gates defined in the Product DevelopmentFramework. The Product Development Framework sets requirements forassessingitems throughout the whole product lifecycle. Framework stage gaterequirements can be found in Appendix B.

 NOTE 5 Guidance on the products that require acceptance isavailable from the Product Acceptance process specialists, or via the ProductAcceptance page on the Network Rail corporate website.

 NOTE 6 Alignment with challenge statements will not apply tochanges to existing approved products, such as the addition of minorcomponentry.

 NOTE 7 Security risk (Cyber security, crime and terrorism)should be considered and where appropriate, a risk assessment completed toidentify mitigations for any increase in risk likelihood or security impact theproduct may introduce.

 This module does not apply to:

 1. civil engineering infrastructure, as defined inNR/L2/CIV/003, which includes:

  a. structures(including equipment and support structures);

  b. buildings andother civil engineering infrastructure that have been designedfor a unique application;

 2. non-Network Rail owned trains and rolling stock;

 3. depots, sidings and other facilities off the operationalinfrastructure.

 NOTE 8 Network Rail equipment or products that are mountedon, or installed in, railway vehicles that Network Rail intends to use for itsown purposes are included in the scope of this module.

The use of accepted products will also be subject to additional requirements if they fall withinthe scope of the following modules:

  a) compliance withinteroperability regulations for infrastructure projects described inNR/L2/RSE/100/03;

  b) application of CSMRA, described in NR/L2/RSE/100/02.

NOTE 9 any technology-based solution being developed forimplementation on the operational railway, needs to be assessed using CSM RA.

NOTE 10 competence requirements for the people involved inapplying CSM-RA are located in Appendix C of NR/L2/RSE/100/02.

Purpose

This process provides assurance to the Network Rail Assurance Panel (NRAP) that products accepted for use on or about Network Rail infrastructure are:

a) safe;

b) compatible;

c) reliable;

d) fit for purpose; and

e) do not export unacceptable risks to Network Rail infrastructure.

The implementation of this module helps to:

1. provide a systematic, structured and robust assessment of risks associated with hazards during product acceptance of products that have been modified or used in different applications in accordance with the common safety method (CSM) on risk evaluation and assessment;

2. confirm the safety requirements necessary to mitigate risks to an acceptable level have been determined; these include those contained in adopted standards;

3. confirm evidence that all identified safety requirements have been complied with and that safety measures are in place;

4. confirm that supporting conclusions and justifications have been suitably recorded.

It is part of a suite of modules governed by NRAP to provide appropriate review prior to projects, products and vehicles being brought into service.
