1、 Standard Basic Information
GB 44703-2024 "General Requirements for Optical Radiation Safety" was jointly released by the State Administration for Market Regulation and the
National Standardization Administration on September 29, 2024. It is the first top-level mandatory national standard in the field of optical radiation
safety in China and will be officially implemented on October 1, 2026. This standard fills the gap in the mandatory basic safety standards for incoherent
optical products in China. All applicable laser products produced and sold domestically must pass compliance testing and be labeled with unified safety
signs.
2、 Scope of application
This standard is applicable to laser products within the wavelength range of 180 nm to 1 mm, covering industrial lasers, medical laser equipment,
communication laser modules, laser display/lighting products, laser components in consumer electronics, etc. It also covers the safety control of light
radiation during the operation of these products.
3、 Testing core content
The standard specifies the general requirements for optical radiation safety from four dimensions:
Risk grading detection
Establish a dual track system of "professional classification+general grading" according to the standard. The general classification is divided into four
levels from low to high: exemption level (no risk of injury), low risk level (safe for short-term scanning, risk of injury for long-term direct vision), medium
risk level (staring can cause eye or skin damage), and high risk level (direct irradiation or diffuse reflection may cause injury). The professional classification
still needs to determine the specific category based on the achievable emission limit (AEL) according to GB/T 7247.1.
Risk identification detection
The product must have both a universal identification and a professional identification. The universal logo adopts a four-color arrow design (green/yellow/
orange/red), which is easy for ordinary people to recognize intuitively; Professional signage includes three types of graphic signs: warning, prohibition, and
instruction. 3R class and above laser products also need to add laser window markings on the output window.
Product safety control testing
Require the inclusion of light radiation safety risk levels, safety labels, and engineering control measures in product specifications and manuals. Low risk and
above products must be operated according to their intended use and instructions, identifying risk sources and taking corresponding control and protective
measures.
Work process safety control detection
Standardize from both technical and management perspectives: at the technical level, it is required to identify risk sources and take engineering control
measures; At the management level, it is explicitly stated that the management of light radiation safety will be incorporated into the occupational health
and safety management system.
4、 Testing criteria and methods
The professional classification of laser products is determined according to GB/T 7247.1 (equivalent to IEC 60825-1), and the laser safety level (Class 1,
1C/1M/2/2M/3R/3B/4) is determined by measuring parameters such as wavelength, output power, and achievable emission limit (AEL), and then mapped
to a general level four risk level.
5、 Preparation materials for inspection
Before sending for inspection, it is necessary to prepare: product technical specifications (including core parameters such as wavelength, power, pulse width,
repetition rate, etc.), product user manual, circuit schematic, electronic document of product safety label (indicating level, wavelength, maximum output
power, etc.). The submitted sample must be completely consistent with the mass-produced version. If the optical path structure or laser module is changed
after testing, the original report will be invalidated.
6、 Detection cycle
The regular testing cycle is 7-10 working days; If the initial test fails and requires rectification and retesting, an additional 3-5 working days will be added.
The safety inspection cycle for laser products is usually 2 weeks, and projects that include complete risk classification and identification assessment may
require longer time.
7、 Compliance recommendations
Considering that the standard will be enforced on October 1, 2026, it is recommended that relevant enterprises start compliance preparation work from
today onwards. The key points include: identifying whether the product falls within the scope of standard application, conducting pre assessment against
risk grading requirements, checking whether existing labels comply with the new standard requirements, and incorporating light radiation safety management
into the enterprise's occupational health and safety management system. It is recommended that enterprises complete the first batch of inspections before
the end of 2025, and reserve sufficient time for inventory digestion and label rectification.
8、 Selection of Testing Institution
Third party testing laboratories with CNAS and CMA qualifications should be selected, and their testing capabilities authorized by GB 44703 and GB/T 7247.1
should be verified to ensure that the testing reports have legal validity and international mutual recognition.
