• Description:
  Confusion and concern has arisen in the nondestructive testing (NOT) industry regarding the applicability of certain ultraviolet (UV) producing lamps in the fluorescent liquid penetrant and magnetic particle inspection technique lies described in MIL- STD-6866 and MIL-STD-1949. It appears that the confusion arises from certain ambiguities in the standards themselves relating to Types I and II penetrants and fluorescent magnetic particles and also from inadequacies of most of the visible light-measuring equipment used in such measurements and of interpretation of the measurements. A solution IS presented combining the use of suitably calibrated photometers, special eye wear, and clarification of the military standards that should eliminate all these problems as well as improve overall system sensitivity.
