These measures should include provisions to ensure that appropriate quality standards are included in design documents and that deviations from established standards are controlled. A process should also be established to determine the suitability of equipment that is essential to safety-related functions and to identify, control, and coordinate design interfaces between participating design organizations. SRP Section 3.11 cites staff positions that require complete and auditable records of the applicant's equipment qualification program, including the results of equipment qualification testing. NUREG-0588, Appendix E, and IEEE Std 323, Section 8, include documentation requirements for the methods and results of environmental qualification for equipment important to safety that is located in a harsh environment. Appendix E to Regulatory Guide 1.89 provides guidance for documenting environmental qualification of electrical equipment covered by 10 CFR 50.49.
