GB 44703-2024General requirements for optical radiation safety (English PDF)

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.

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

GB 44703-2024 is the Chinese mandatory national standard for optical radiation safety. It applies to laser products in the 180 nm to 1 mm band and to incoherent optical products in the 200 nm to 3 micrometre band, and to the working processes in which they are used, so it reaches from laser cutters and medical lasers to LED and lamp products. The standard sets the classification of optical radiation safety risk - a general classification and a professional one - the labelling that each risk level requires, the safety control requirements for the product itself, and the safety control requirements for the work process around it. Compliance is compulsory for the products within its scope placed on the Chinese market. It was issued on 29 September 2024 and applies from 1 October 2026.

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.
