What is product acceptance?
The product acceptance process gives us the assurance that products accepted for use on or about our infrastructure are:
- safe
- compatible
- reliable
- 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.
Watch our video below to find out more about product acceptance
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.
This includes:
- 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.
You can view the examples of items that require approval (PDF). Please note that this list is not exhaustive and advice may be required to determine whether your product requires approval.
Please also refer to the guidance document – How to decide what needs product acceptance (PDF) for further details on the products that this process applies to.
See the attached Product Acceptance Service Guidance Note (PDF 2 MB) for more information on the Product Acceptance process and for information on how to obtain our standards.
For further guidance please see our FAQ document or email us at prodacc@networkrail.co.uk.

How to apply for product acceptance
Applications need to be submitted by or on behalf of a Network Rail operative (applicant), who is prepared to act in a sponsorship capacity and who can demonstrate a Network Rail business requirement. Or, for Plant Assets, such as road-rail vehicles or on-track machines, by an authorised Plant Assessment Body (PAB).
You or the Network Rail Applicant (sponsor) will need to provide justification by demonstrating monetary, safety and / or performance benefits to Network Rail.
The roles and responsibilities of the Applicant (sponsor) are defined in our Guidance for Product Acceptance Sponsors document.
Applications should be submitted when products or systems have been fully developed and have reached Rail Industry Readiness level (RIRL) 6. Definitions of the Rail Industry Readiness levels are available within section 8 of the Guidance Note (PDF).
If your product has not yet reached RIRL6, please refer to our Challenge Statements.
Acceptance is subject to standard terms and conditions, which are available in the sample Certificate of Acceptance (PDF)
