4-44. 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.
(3)
Absorption of oil or grease on a clean filter paper from a surface wipe.
b. Ultraviolet Light Method. The ultraviolet method for detecting hydrocarbons may be employed in different ways.
WARNING
Most ultraviolet lamps contain mercury. Extreme caution should be taken not to break the mercury vapor lamp which will
contaminate the component or pipe being inspected and may also cause human injury.
