3-4.2.2 Valve Line-up/Cycle Isolation. A cycle isolation checklist shall be developed to meet
the goals of the test. The checklist should be divided into three categories: (a) manual valve isolation
checklist, (b) automatic valve isolation checklist, and (c) test valve isolation checklist.
(a) The manual valve isolation. This checklist should be an exhaustive list of all manual valves that
should be closed during normal operation, and that affect the accuracy or results of the test if they are
not secured. The plant equipment should be operated in a manner consistent with the basis of design or
guarantee or in a manner that will reduce the overall test uncertainty, and in a manner that will permit
correction from test operating conditions to base reference conditions. These valve positions should be
checked before and after the test.
