1.1本规程提供了分光光度法，用于检测物体颜色样本中是否存在荧光。 注1-由于材料制造商通常有意添加荧光剂（着色剂、增白剂等），因此通常可以从材料制造商处获得样品中是否存在荧光特性的信息。 1.2本规程要求使用分光光度计，该分光光度计在340至700 nm的波长范围内照射样品，并允许根据需要改变样品上照明的光谱分布。 1.3在上述限制范围内，本惯例在范围上是通用的，而不是特定于仪器或材料。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

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 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 and health practices and determine the applicability of regulatory limitations prior to use.
