RAL undertake a variety of activities associated with rail certification processes, as follows:

  • The Rail Industry Supplier Approval Scheme (RISAS) has been established to provide both suppliers and users of railway industry products and services with a standardised method of supplier approval which will be recognised and accepted throughout the industry (thereby eliminating duplication in individual auditing and assessment work).

  • Railway Approvals have established a documented supplier accreditation system which has been accredited by RSSB to operate as a Railway Industry Supplier Approval Body (RISAB). This accreditation has been undertaken in accordance with RSSB standard RISAS/004.

  • RISAB work is undertaken within the scope of Railway Approvals' RISAB accreditation (by Product Groups). Details of the accreditation scope is maintained by RSSB and advised to the industry via the RISAS IT application.

  • RISAB Supplier auditing, assessment and certification work is undertaken in accordance with the RSSB RISAS standard RISAS/003 and other relevant mandatory requirements.


Currently Railway Approvals are able to issue RISAS certificates against products in the following code groups:

If you have a requirement for RISAS certification for products not covered by the Railway Approvals scope we can discuss extending our scope to meet your specific needs.
