Description


IEC 61855 Hair Dryer Air Blockage Test Machine For Airflow Blockage And Motor Stall Testing


Product Overview:


The Air Blockage Test Machine is designed for airflow blockage and motor stall testing of hair dryers and hot-air hair styling appliances.

By simulating partial and full airflow obstruction, the system evaluates thermal safety, motor overload protection, and over-temperature response, ensuring product compliance with international safety standards.

The equipment complies with GB/T 23106-2024, QB/T 1876-2023, and IEC 61855:2022.



Applicable Products:


  • Handheld hair dryers

  • Heated hair styling appliances



Test Purpose & Principle:


Test Purpose

  • Air blockage performance testing (50% / 100%)

  • Motor stall overload protection verification

  • Temperature rise evaluation of critical parts

  • Safety device response validation

Test Principle

Motor Stall Simulation

  • When the motor rotor is mechanically locked:
  • Motor current increases to 3–8 times the normal operating value
  • The system evaluates:
  • Motor burnout risk
  • Winding short/open circuit conditions
  • Accuracy and response time of thermal protectors

Airflow Blockage Simulation

By mechanically blocking the air inlet/outlet:

  • Simulates 50% and 100% airflow blockage
  • Evaluates:
  • Surface temperature rise at key locations (handle, outlet)
  • Effectiveness of thermal cut-off devices
  • Heating element abnormal conditions (overheating, glowing)
