Our product acceptance process
What is product acceptance?
The product acceptance process gives us the assurance that products accepted for use on or about our infrastructure are:
- fit for purpose
- do not export unacceptable risks to Network Rail infrastructure.
Only accepted products, except those allowed by NR/L2/RSE/100/05, shall be used on the rail infrastructure.
Do I need to apply for acceptance?
Network Rail standard NR/L2/RSE/100/05, Product introduction and change, governs the process for the acceptance of products.
- new or modified products, materials, equipment, and systems
- changes of application
- road-rail vehicles or attachments, and rail-mounted machines, on-track machines, road plant and portable and transportable work equipment that could affect or interact with the infrastructure.

Please also refer to the guidance document - How to decide what needs product acceptance for further details on the products that this process applies to.
