upling to the support. If the equipment is installed in a nonoperational mode for the support test, the response in the test at the equipment mounting location should be monitored and characterized in the manner as stated in subsection II.1.a(3) above. In such a case, equipment should be tested separately for operability and the actual input motion to the equipment in this test should be more conservative in amplitude and frequency content that the monitored response from the support test. (4) The criteria of subsections II.1.a(3), (4), (5), (6), (7), (8), and (13) above, are applicable when tests are conducted on the equipment supports. c. Verification That Seismic and Dynamic Qualification Is Performed in the Proper Sequences of the Overall Qualification Program As defined in Part B of Regulatory Guide 1.100, IEEE Std. 344-1975 is an ancillary standard of IEEE Std 323-1974 (endorsed with exceptions by Regulatory Guide 1.89. In accordance with this standard, for plants whose construction permit SER is dated July 1, 1974, or later, the seismic and dynamic testing portion of the overall qualification should be performed in its proper sequence as indicated in Section 6 of IEEE Std. 323-1974.The seismic and dynamic qualification testing performed in accordance with Regulatory Guide 1.100 and ANSI/IEEE Std 344-1987 as part of an overall qualification program should be performed in the sequence indicated in Section 6 of IEEE Std 323-1974 (endorsed with exceptions by Regulatory Guide 1.89). 40 2. Instrumentation described in Regulatory Guide 1.97, including associated mountings, should be tested under appropriate seismic and dynamic loadings as described therein, thereby ensuring that the instruments will continue to monitor plant variables and systems after a seismic event and/or accident.41 3.10-9 DRAFT Rev. 3 - April 1996 2. For plants for which the CP application was docketed before October 27, 1972, applicants should describe the extent to which the seismic and
