Description of ASTM-E2501 2011ASTM E2501 - 11Standard Specification for Light Source Products for Inspection of Fluorescent CoatingsActive Standard ASTM E2501 | Developed by Subcommittee: E12.05 Book of Standards Volume: 06.01 ASTM E2501Abstract
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. Also, this specification establishes the radiometric requirements of the light source product in terms of required wavelength range and minimum irradiance. Safety requirements shall be established for the light source product necessary to ensure the product will not pose a threat to visual health. Irradiance test method shall be performed to conform to the specified requirements, in accordance to the test method. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Significance and Use
Light source products conforming to this specification are intended to be used in conjunction with coatings specially formulated with fluorescent colorants as a system for the visual detection of defects in industrial protective coatings. Visible fluorescence from the coating enhances the contrast of coating irregularities and defects and is produced by excitation of visible-activated fluorescent colorants in the coating. Light source products with defined wavelength and intensity properties are required to produce adequate visible fluorescence for easy visual location of defects. A light source product is considered to consist of a light source component incorporated into an optical, electrical, mechanical, and power supply system that makes it suitable for use in an industrial environment. The entire light source product is subject to this standard. The light source component and any subassemblies of the light source product are not subject to this standard This specification is limited to light source products providing excitation in the range from 400 to 420 nm. 1. Scope
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.
