– “Examination applies to quality control functions performed by the manufacturer (for components only), fabricator, or erector. Reference in this Code to an examiner is to a person who performs quality control examinations.”. – ASME B31.3.
– Testing: means Leak tests prior to operation to ensure tightness, such as (Hydrostatic, Pneumatic tests).
