4. GENERAL REQUIREMENTS

4.1 General measurement requirements. The design activity shall ensure the following actions are accomplished for the affected systems and equipment throughout their life cycle.
a. All parameters that require measurement to ensure proper and accurate operation of the system and equipment are identified and documented.
b. Calibration and measurement actions are conducted as required to maintain accurate operation. Such actions are to be accomplished at all applicable system and subsystem levels and are appropriately integrated into the total system requirements.
c. All parameters are readily accessible and measurable in a manner that minimizes the number and duration of the tests required.
d. Measurement traceability of all system and subsystem parameters is documented.
