Refrigerator Door Durability Test Equipment IEC60335-2-24
Interlocking Device Tester
Standard Compliance
This equipment is designed according to IEC60335-2-24:2017
“Household and similar electrical appliances – Safety – Part 2-24:
Particular requirements for refrigerating appliances, ice-cream
appliances and ice-makers, IDT”.
Application
It is mainly used to test the durability and stability of
interlocking devices on vertical refrigerator doors. The system
also assists in other repeated door opening and closing tests, such
as defrost performance testing and refrigerant leakage testing.
Suitable for refrigeration appliances with either two vertical
doors on the same side or a single door design.
Test Principle
The test process is controlled through a customized program. Servo
motors drive manipulators equipped with vacuum suction cups to
repeatedly open and close refrigerator doors at a set speed. The
system verifies the long-term stability, endurance, and safety of
the interlocking device.
Structural Design
Electrical Control Cabinet: Includes load voltage regulating device
for stable and accurate testing.
Frame & Manipulators: Robust structure ensuring precise motion
control.
Vacuum Suction Cups: Securely attach to refrigerator doors during
testing.
Servo Motor Drive: Provides smooth and programmable door
opening/closing operations.
Technical Specifications
Test Samples: Refrigeration appliances (vertical refrigerators with
2 doors on the same side or 1 door)
Equipment Dimensions (W × D × H): 1500 × 1300 × 2000 mm
Equipment Weight: Approx. 250kg
Control System: Programmable with automated operation
Test Actions: Repeated opening and closing cycles with adjustable
speed and frequency
Key Features
Fully compliant with IEC60335-2-24 international safety standards.
Realistic simulation of door operations with servo-driven
manipulators.
Durable frame structure ensuring long-term reliable performance.
High-precision vacuum suction system for stable door handling.
Supports extended endurance tests for safety and performance
validation.
Easy operation through intelligent control cabinet with
programmable functions.

| Number of vacuum suction cups | 2 pcs
The distances of the two vacuum suction cups can be adjusted, to
match the different height or suction positions of two doors |
| Door Open and Close Method | The Vacuum suction cup sucks on the door tightly, then servo motor
drives the manipulator back and forth, the speed, angle, test
cycles can be set and displayed on the touch screen
|
| Door Open and Close Directions | Right or Left
The suction cups can be installed on the right side or left side,
and there is an expand base plate which can be connected on the
right side or left side of the base plate, thus to match the right
door or left door opening requirements. |
