1.1 本规范规定了用于激发荧光材料的光源产品的要求，荧光材料用作工业涂层缺陷检测系统。这包括检查较长波长的荧光底漆和非荧光面漆。 1.2 本规范规定了光源产品在所需波长范围和最小辐照度方面的辐射要求。 1.3 本规范为光源产品制定了必要的安全要求，以确保产品不会对视觉健康造成威胁。 1.4 以国际单位表示的值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 符合本规范的光源产品拟与荧光着色剂特别配制的涂层一起使用，作为工业防护涂层缺陷目视检测系统。 4.2 来自涂层的可见荧光增强了涂层不规则性和缺陷的对比度，并通过激发涂层中的可见活化荧光着色剂而产生。 4.3 需要具有规定波长和强度特性的光源产品，以产生足够的可见荧光，从而便于目视定位缺陷。 4.4 光源产品被认为是由并入光学、电气、机械和电源系统的光源组件组成，使其适合在工业环境中使用。整个光源产品均符合本标准。光源组件和光源产品的任何子组件不受本标准的约束。 4.5 本规范仅限于提供400 nm至420nm。

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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. ====== Significance And Use ====== 4.1 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. 4.2 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. 4.3 Light source products with defined wavelength and intensity properties are required to produce adequate visible fluorescence for easy visual location of defects. 4.4 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. 4.5 This specification is limited to light source products providing excitation in the range from 400 nm to 420 nm.
