Appendix A:《CNAS"Method for Calculating Recognition Reviewer Days"

A.1 Document Review

A.1.1 For preliminary or re-evaluation institutions, with a review team of 5-10 members, or with 2-4 locations, the document review is set at 2 person-days.

A.1.2 For initial or re-evaluation institutions, where the review team has more than 10 members, or there are 4 or more locations, the document review is set at 3 person-days.

A. 1.3 The number of days for the review of documents supervising and expanding the scope of recognition is generally half that of the preliminary assessment.

A.2 On-Site Assessment The on-site assessment for preliminary review, supervision, re-evaluation, and expansion of recognition scope includes two parts: management system review and technical capability review.

The total person-days for on-site review are the sum of the management system review and the technical capability review.

The number of person-days for the review of the expanded scope of recognition shall be calculated in accordance with the requirements of Clause A.2.2.1.
