1.1 This practice provides spectrophotometric methods for detecting the presence of fluorescence in object-color specimens.
Note 1: Since the addition of fluorescing agents (colorants, whitening agents, etc.) is often intentional by the manufacturer of a material, information on the presence or absence of fluorescent properties in a specimen may often be obtained from the maker of the material.
1.2 This practice requires the use of a spectrophotometer that both irradiates the specimen over the wavelength range from 340 nm to 700 nm and allows the spectral distribution of illumination on the specimen to be altered as desired.
1.3 Within the above limitations, this practice is general in scope rather than specific as to instrument or material.
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
