"The effective removal of particulate matter from the system by the blow-out operation should be demonstrated by the use of target plates mounted at the discharge end of the pipeline. Targets may be polished metal or cardboard on plywood... As an alternative, steel plates may be used with a uniform smear of oxygen-compatible grease to trap particulate material.

The blowout shall be judged as complete when there is no perceptible evidence of particles on the target detected by the naked eye or touch (i.e. scars or pits >0.2 mm). For grease-smeared plates there shall be no evidence of collected particles as detectable by the naked eye."
