RMP.6:4.2 - Reuse the examination that already answers

An existing result can answer the present credibility question when its claim, relevant material, Method, criterion, assumptions and scope support the proposed use. Recover those relations and the result’s qualifications. Repeat only the affected examination when a changed premise, execution defect or new use makes it necessary.

A result’s age alone does not invalidate an unchanged premise. Actual expiry of a required calibration, permission or applicable criterion can matter. The relevant owner supplies that condition; RMP.6 does not infer either validity or invalidity from a date label alone.

If the existing basis is sufficient for this question, return the answer and its needed limitation. The current account may already be complete. An unused test catalogue, comparison table or separate justification for not testing is unnecessary.
