4-37. Hydrocarbon Inspection and Analysis.
a. Visual Method. By definition, visibly clean is the absence of all particulate and non-particulate matter
visible to the normal unaided (except for corrected vision) eye. Particulate is identified as matter of miniature
size with observable length, width, and thickness. Non-particulate is film matter without definite dimension.
Examples of visual inspection are:
(1) A clean cloth placed over the discharge end may collect particulates and debris when air or nitrogen
is blown through the system.
(2) A component that has been in service may have visible signs of grease, dirt, etc.
