ASTM E2501-11

1.1 This specification provides the requirements for light source products intended for excitation of fluorescent materials used as a system for detection of defects in industrial coatings. This includes the examination of both longer wavelength fluorescing primer coatings as well as non-fluorescent top coatings.

1.2 This specification establishes the radiometric requirements of the light source product in terms of required wavelength range and minimum irradiance.

1.3 This specification establishes safety requirements for the light source product necessary to ensure the product will not pose a threat to visual health.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
