Radio Frequency Testing

1、 The necessity of certification 
  
Legal mandatory requirement: Failure to pass KC certification will result in customs detention and face a maximum fine of 30 million Korean won and recall risk 
E-commerce platform requirements: Korean Coupang/Naver and other platforms must display KC certification numbers 
  
2、 Core certification type 
  
KC Safety Certification 
Suitable for all types of baby monitors 
Management organization: Korea Institute of Technical Standards (KATS) 
KC-RF certification 
Required condition: Includes wireless functions such as Wi Fi/Bluetooth 
Management organization: Korea Radio Research Agency (RRA) 
  
3、 Certification process (6-8 weeks) 
  
preliminary preparation 
Confirm applicable standards: 
Safety standard: KS IEC 60335-2-XX 
Wireless standard: KN 301 489-1 
Choose a Korean authorized laboratory (such as GTG Guangce Group) 
Technical document preparation 
Korean instruction manual (including safety warnings and applicable age) 
Circuit diagram and PCB layout diagram 
Key component certification documents (UL/VDE certificates) 
Sample requirement: 3 complete machines (including matching power adapters) 
Laboratory testing projects 
Electrical safety testing: 
Voltage withstand test: 1500V/60 seconds (leakage current ≤ 0.5mA) 
Temperature rise test: shell temperature ≤ 60 ℃ 
Mechanical safety testing: 
1-meter drop test (shell intact/functional) 
Chemical safety testing: 
Heavy metal detection: lead ≤ 90ppm, cadmium ≤ 75ppm 
Wireless Radio Frequency Test (KC-RF): 
2.4GHz frequency band transmission power ≤ 20dBm 
Factory Audit 
First certification and annual mandatory review 
Review focus: 
Battery assembly process record (welding material batch number+operator number) 
Incoming inspection report (batteries must comply with KS C IEC 62133) 
Evidence collection and annotation 
KC Logo Specification: 
Size ≥ 5mm 
Label certification number (format example: KR-X-XXX-XXXXX) 
The product must be labeled with: 
Voltage parameters (110V/220V 60Hz) 
Manufacturer information 
Korean agent contact information
