Introduction
In-depth interpretation of the National Standard of the People's Republic of China GB/T 42750—2023
| Standard dimensions | Content comparison | Scope of application | Technical requirements |
|---|---|---|---|
| Measurement conditions | - Standard atmospheric conditions (temperature, humidity, pressure) - Darkroom environment requirements (illuminance, reflectance) - Power supply stability | Preparation for all wearable device tests | The deviation range is controlled within 0.2% to ensure data reliability |
| Measurement equipment | - Spectral radiation analyzer - Irradiance receiver - Radiance receiving device - Variable angle test bench - Standard light source | Professional laboratory environment | Equipment needs to be calibrated regularly to ensure measurement accuracy |
| Types of optical radiation hazards | - Ultraviolet, near-ultraviolet, and infrared hazards to the eyes - Blue light and thermal hazards to the retina - Ultraviolet, infrared and thermal hazards to the skin | Eye-worn devices and skin contact devices | Select measurement parameters according to different hazard types |
Analysis of standard formulation background and technological evolution
With the popularization of wearable devices, the issue of optical radiation safety has become increasingly prominent. GB/T 42750-2023 fills the gap in this field in China. It refers to international standards such as IEC and ISO and develops safety measurement methods applicable to different types of wearable devices in combination with China's actual situation.
Explanation of professional terms and practical application cases
- Eyewear equipment: refers to products that directly contact the eyes or emit light radiation at a very short distance, such as AR/VR glasses.
- Skin contact equipment: refers to products that directly contact the skin or emit light radiation at a very short distance, such as smart wearable health monitoring devices.
Implementation recommendations
To ensure that the optical radiation safety of wearable devices complies with national standards, the following measures are recommended:
- Strictly test under standard conditions to ensure stable environment and power supply.
- Select measuring equipment that meets the requirements and calibrate regularly to ensure accuracy.
- Select the corresponding measurement method and parameter settings according to different product types.
- Strengthen the safety awareness of operators and avoid looking directly at the light source.
