Combinations of the elements listed above may be specified as
appropriate to provide complete PMT. Examples of
maintenance performed and associated PMT are given in
Appendix C. The examples are provided as guidance only. The
actual required testing should be tailored to the specific
Control of Postmaintenance Testing
Control and documentation of PMT activities are a part of the facility's work
control and equipment status control systems.
During the initial processing of an MJR, the maintenance
planner should include predefined PMT in job instructions
based on consultation with the owner/operator.
Appendix A, PMT Control Form, should be filled out by the
planner and attached to the MJR, as appropriate.
When a maintenance activity involves several different tests, a
separate PMT Control Form may be used to document each
The maintenance planner should obtain assistance from the
owner/operator, technical support, the responsible system
engineer, or other groups as needed to ensure that all testing
requirements and acceptance criteria are specified.
The maintenance supervisor responsible for the work should
review the MJR prior to beginning work, including the PMT
Control Form. During this review, the supervisor is responsible
for understanding the specified testing for the intended work
and providing feedback for inadequacies.
The owner/operator should approve the MJR prior to the start
of maintenance work.
