一、制定背景JJG879-2002《紫外辐射照度计检定规程》(以下简称“旧规程”)自2002年4月15日发布至今已14年。近年来,紫外辐射照度计在无损检测、光刻、消毒、固化等领域得到了广泛应用,但是不同仪器的性能指标差异较大,测量结果之间的不一致性日益凸显。旧规程中所规定的技术指标、技术要求、检定方法已不能满足科技 First, the development of the background JJG879-2002 “UV irradiance meter verification procedures” (hereinafter referred to as “old procedure ”) since April 15, 2002 has been released for 14 years. In recent years, UVR meter has been widely used in nondestructive testing, photolithography, disinfection, curing and other fields, but the performance of different instruments vary greatly, the inconsistency between the measurement results has become increasingly prominent. The old rules stipulated in the technical indicators, technical requirements, test methods can not meet the science and technology
