灯和灯系统的光生物学安全 第6部分：紫外线灯产品

[中文适用范围]： IEC 62471 的该部分为紫外线灯产品提供了光辐射安全要求，包括 UV LED 灯产品。本文件提供了以下要求：光辐射安全评估和紫外线产品风险组；用于安全措施的用户信息；紫外线灯产品的适当标签。本文件涉及那些紫外线发射作为产品主要目的的产品，且在 180 nm 至 3000 nm 之间发射的辐射功率中，超过一半位于 180 nm 至 400 nm 的光谱区域。如果 180 nm 至 3000 nm 之间发射的光辐射超过一半位于 180 nm 至 400 nm 光谱区域之外，则应使用基础标准 IEC 62471。本文件涵盖主要发射紫外线辐射的医疗诊断和美容设备/产品。由于紫外线辐射的光生物效应基于接收的总累积照射量（剂量），本文件依赖“时间加权平均”照射的概念，其中确定风险组的评估距离是基于现实的照射距离和照射持续时间。也就是说，不预计人们会在非常近的距离（例如 20 厘米至 30 厘米）长时间暴露。本文件提供的应用特定且现实的评估距离和具体指导，而非 IEC 62471 中应用未知且时间加权平均照射非应用特定的更通用值。本文件不提供以下要求：主要发射可见光（如 GLS - 通用光源）和/或红外辐射能量的灯；用于通用照明、红外照明或加热的灯产品（由单独标准处理）；用于美黑的荧光紫外线灯（由 IEC 60335-2-27 和 IEC 61228 涵盖）；医疗设备/产品（见 IEC 60601-2-57），但涵盖紫外线医疗诊断产品；非光辐射危害，如臭氧、汞等。 [外文原描述]： IEC 62471-6:2022 IEC 62471:2006/CIE S009:2002. IEC 62471 covers light emitting diodes (LEDs), incandescent, low- and high- pressure gas-discharge, arc and other lamps. It also covers lamps which are designed primarily to emit ultraviolet radiant energy, such as ultraviolet sources intended to excite fluorescence of irradiated materials, for insect light traps, for scientific studies, mineral identification, for non-destructive testing, germicidal irradiation, and other purposes. This part of IEC 62471 provides the optical radiation safety requirements for ultraviolet lamp products, including UV LED lamp products. This document provides requirements for: optical radiation safety assessment and ultraviolet-product risk groups; user information for safety measures; appropriate labelling of ultraviolet lamp products. This document addresses those lamps and lamp products where the ultraviolet emission serves the primary purpose of the product and where more than half of the radiant power emitted between 180 nm and 3 000 nm is in the spectral region 180 nm to 400 nm. If more than half of the optical radiation emitted between 180 nm and 3 000 nm is outside of the spectral region 180 nm to 400 nm, then the base standard IEC 62471 should be used. This document covers medical diagnostic and cosmetic devices/products that emit primarily UV radiation.
