Radio Frequency Testing

Want to sell domestic Bluetooth earphones to the European Union? 
Many cross-border sellers are stuck in the CE certification stage! 
The EU's regulation of wireless products can be called an "iron wall", 
Today, the GTG editor will take you to learn how to obtain certification and avoid pitfalls! 
  

  
1、 Why is CE certification necessary? 
  
The EU has very strict regulations on wireless products, and they must complete CE certification before they can be legally sold within the country. 
Unverified products may not only be seized by customs, but may also face high fines or even mandatory recalls! 
  
  
2、 What are the core testing projects? 
  
Your headphones must pass these 'hardcore levels': 
1. Electromagnetic compatibility (EMC) 
Ensure that the headphones do not interfere with surrounding devices while working 
2. Radio Equipment Directive (RED) 
Check whether key indicators such as wireless frequency band and power are compliant 
3. Additional items (if involved) 
• Built in lithium battery → requires battery safety testing 
• Supports charging → Must comply with low voltage command 
  
  
3、 Practical Guide 
  
Step 1: Choose the right laboratory 
Identify an officially recognized laboratory by the European Union 
Beware of counterfeit certificates, otherwise all investments will go to waste! 
  
Step 2: Prepare all technical documents 
including: 
▪️  Product Technical Parameters 
▪️  Circuit design diagram 
▪️  User manual (must include safety warnings and EU representative information) 
Step 3: Standardize labeling and packaging 
CE mark height ≥ 5mm (must be clear and eye-catching! ） 
The outer box, body, and instruction manual must all reflect certification information
