Radio Frequency Testing

With the popularization of smart glasses in the global market, Japan, as a country with strict technical supervision, has formed a multi-level certification system for its access requirements. Enterprises need to have a systematic understanding of various regulatory requirements in order to ensure that their products enter the Japanese market in compliance. This article will comprehensively analyze the key certification path for the export of smart glasses to Japan. 
  
1、 PSE certification: the core threshold for electrical safety 
  
According to Japan's Electrical Appliance Safety Law, smart glasses, as live products, must pass PSE certification. This certification is divided into two categories based on risk level: 
Diamond shaped PSE: Suitable for high-risk specific electrical products, smart glasses usually belong to this category. Testing and factory inspection must be completed by an authorized agency of the Japanese Ministry of Economy, Trade and Industry, with a certificate validity period of 3-7 years 
Circular PSE: Suitable for general electrical appliances, can be self declared 
Key technical standards: Safety design must comply with JIS C 62368-1 (Safety Standard for Audio, Video and Information Technology Equipment), and battery modules must meet the safety requirements of JIS C 8712 
  
2、 TELEC certification: mandatory license for wireless functionality 
  
If smart glasses have wireless communication functions such as Bluetooth and Wi Fi, they must be certified by TELEC (Japan Radio Equipment Compliance Certification). The core requirements include: 
RF performance: 2.4GHz frequency band equipment transmission power (EIRP) ≤ 100mW, frequency error ≤± 50ppm 
Electromagnetic compatibility: The radiation disturbance value must meet the CISPR 22 limit and pass the electrostatic discharge immunity test 
Identification specification: The product body must be marked with the GITEKI logo and certification number (such as TELEC-2025-XXXXXXX) 
The certification process includes sample testing (providing fixed frequency and mass production prototypes) and technical document review. The certificate is valid for 5 years 
  
3、 Other necessary certifications and filings 
  
1. METI filing: After passing PSE certification, Japanese importers must complete the filing with the Ministry of Economy, Trade and Industry, and the product label must reflect the filing number 
2. PMDA filing: If the product claims medical functions such as vision correction, it needs to be filed with the Japanese Ministry of Health, Labour and Welfare as a Class I medical device, and the process includes manufacturer registration (2-3 months) and product registration 
3. Battery safety certification: The built-in lithium battery must pass UN38.3 transportation safety testing and JIS C 8712 standard certification 
  
Conclusion 
  
The export of smart glasses to Japan requires the establishment of a three in one compliance framework of "safety+wireless+medical": basic electrical safety relies on PSE certification, wireless functions must obtain TELEC certification, and medical features trigger PMDA filing. Enterprises need to simultaneously pay attention to the upgrade of EMC and data regulations in 2025, and avoid market risks through forward-looking design.
