INDEPENDENT VERIFICATION FUNCTION OF THE DEMONSTRATION OF COMPLIANCE

(a) The independent verification function of the demonstration of compliance should consist of the verification by a person that did not create the compliance data. Such a person may work in conjunction with the individuals that prepare compliance data.

(b) The verification should be shown by signing compliance documents, including test programmes and data.

(c) For a product, there is normally only one compliance verification engineer that is nominated for each relevant subject. A procedure should cover the non-availability of nominated persons and their replacement, when necessary.

(d) For STC cases, when compliance statement and associated documentation are produced by the TC holder, and when this data is approved under the system of the authority of TC holder, then the STC applicant does not need to provide, within its own DOA, the independent verification function that is required in point 21.A.239(d)(2) for that data.
