Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents" Drafting. Please note that some of the contents of this document may involve patents. The issuing organization of this document does not assume the responsibility for identifying patents. This document is proposed and coordinated by the Ministry of Industry and Information Technology of the People's Republic of China.

Introduction

This document aims to protect the health of users and related personnel by regulating the light radiation safety of luminous products and their working processes. In the process of formulation, the rapid growth of demand for high-brightness luminous products and industrial development in my country's market economy and social development were taken into consideration. Factors such as trends are the most basic general requirements that should be followed to ensure optical radiation safety and public health. The standards involved in the technical content of this document include IEC 60825 (all parts) and IEC 62471 (all parts) corresponding to GB/T 7247 (all parts) and GB/T 30117 (all parts), including the optical radiation safety standards for typical products independently formulated by my country. These standards specify the optical radiation safety compliance requirements and corresponding verification methods for different product categories, providing guidance for relevant departments, industries, and enterprises. Provide a basis for ensuring the light radiation safety of luminous products and their working processes. General requirements for optical radiation safety

1 Scope

This document specifies the risk classification, identification and safety control of optical radiation safety of laser products and incoherent optical products and their working processes. General requirements in other aspects. This document applies to laser products in the 180nm~1mm band and incoherent optical products in the.200nm~3μm band. Optical radiation safety of products and their working processes.

3 Terms and definitions

The terms and definitions defined in GB/T 7247.1 and GB/T 30117.1 and the following apply to this document. 3.1 Optical radiation 3.2 Laser The particles of matter are stimulated to emit and amplify the light radiation produced. Note. Laser has good monochromaticity, coherence and directionality, and is also called coherent light. A device that can generate laser is called a laser. [Source. GB/T 15313-2008, 2.1.1, modified] 3.3 Laser products Products containing lasers. [Source. GB/T 7247.1-2024, 3.48, modified] 3.4 Incoherent light Optical radiation that is not laser or has no coherent properties. 3.5 Products that produce incoherent light. Note. The most common incoherent light products are various lighting fixtures, ultraviolet lamps, projectors, electronic displays, etc. ......
