3.1.1 The applicable equipment/facility owner/operator has overall accountability for
defining PMT, establishing acceptance criteria, and verification that
acceptance requirements are satisfied prior to returning an item to normal
service. Documented PMT is required when specified by the SSC
owner/operator. Checkout and Verification should be performed by the
maintenance craftsperson whenever a Documented PMT is not required.
The objective of PMT is to verify that SSC are capable of performing their
intended function when returned to service following maintenance and to
ensure that the original deficiency is corrected. PMT requires close
coordination among various facility groups and contract personnel. PMT
integrates with the work control system and the Health and Safety permit
system. An effective PMT may be directly related to facility reliability. This
guide does not specifically address the postmodification testing process;
however, most of the methods described may be directly used for
postmodification testing as well.
PMT involves the following key elements:
Responsibilities of each group are clearly defined.
Scope of equipment tested includes all facility equipment.
Specifying appropriate tests includes inputs from maintenance,
owner/operator, and technical support groups.
Guidance is available to planners for identifying appropriate tests.
Testing is conducted with owner/operator's authorization, uses
approved procedures or instructions, and is performed and reviewed by
Tests are conducted under the appropriate system operating parameters.
A form is used to authorize, document, and review the results of PMT.
Posttest system restoration is formally controlled (restoring system to
normal and/or standby modes following completion of PMT).
This guide is intended to assist in the development of PMT activities.
