In certain specific circumstances where a Product is to be used in a local closed ITSO Environment, in advance of wider integration, a more limited certification is possible. Such options must be discussed with ITSO before progressing with Testing and must be accompanied with legitimate business reasons to support the request.

Following successful testing, the limited scope and lack of full ITSO conformance will be noted in Schedule B of the Certificate. The non-conformance and any requirement to obtain a Derogation from the ITSO Board will be detailed in the Schedule.

The award of such a certificate will not of itself allow the use of the Product. This is dependent on the ITSO Board agreeing a Derogation. This must be requested by the Operator intending to use the Product and may involve specific conditions and / or time limits being applied. Registered Suppliers are not to request Derogations. Certificates requiring a Derogation will not normally be published on the ITSO web site.

Derogations will not be granted to extend an expiring certificate.

Derogation requests will be reviewed by the ITSO board at the next meeting.  Please ensure any requests are submitted well before the next board meeting, dates can be found here
