Cadaver or VR work assessment

Does LSDOGs or anyone else have an UK assessment standard for this type of work? If so please can I have a copy.
If not what is the standard likely to look like when it is published?
I am aware of dog teams around the UK offering themselves as 'victim recovery dogs' so would like to know what standard they are accredited against.
