Test it after the work.

Reach for this once the work is done and before you call the job finished.

A system can start and run yet still not perform, and that shows up later as a callback.

Step by step

7
  1. List the tests this work owes

    Write which tests this system needs, in order. Use the maker's instruction and the job documents for methods and values.

    Write down · Note
  2. Treat a first run as a start

    A first start shows the system is whole. It does not show it performs under real load.

  3. Check the instrument first

    Record range, calibration date, and setup. A reading inside its own uncertainty decides nothing.

  4. Run functions in order

    A qualified person runs controls, sequences, and real operating conditions. Later changes mean earlier tests run again.

  5. Make the safeties act

    A qualified person makes each limit and safety act under its real condition. Record the final settings.

  6. Stop if a safety is jumpered

    If a safety, limit, or interlock is jumpered or disabled, keep the equipment out of service. Call a qualified person.

  7. Record starting readings

    Record readings with load and conditions stated. Later visits compare against this set.

Done when

A finished run leaves the ordered test list, readings with instruments and conditions, final settings, and who ran each test.

General guidance for a qualified person, not a finding about any home. The person on site decides.
