Cookware Handle Torque Tester | UL 1026 Handle Strength Test Equipment

Standards and Test Method Support

The KP-DH22 is designed to support the handle strength test for slow cookers according to UL 1026 related requirements.

UL 1026 covers electric household cooking and food serving appliances. For slow cookers and similar appliances with carrying handles, handle strength evaluation is important because the product may be moved while loaded. If the handle or its attachment structure fails during use, hot contents may spill and create a user safety risk.

During testing, the appliance sample is loaded to the required test condition and repeatedly lifted by the handle. The test helps manufacturers evaluate whether the handle assembly, fixing points and surrounding body structure remain secure after repeated mechanical stress.

System Configuration

The KP-DH22 integrates a vertical lifting mechanism, sample holding fixture, cycle counter, control panel, protective enclosure and emergency stop function into one dedicated handle strength testing system.

Operators can set the required number of test cycles through the control panel. After the loaded sample is fixed in position and the protective door is closed, the equipment performs repeated lifting cycles automatically. The system stops when the preset number of cycles is reached.

Although the product may be searched as a cookware handle torque tester, the KP-DH22 is configured for repeated lifting strength evaluation rather than rotational torque loading. This wording helps match buyer search behavior while keeping the technical description accurate.

Key Advantages

Test Capability and Operation Features

The KP-DH22 is engineered for reliable and repeatable handle strength evaluation under controlled lifting conditions.

• Supports handle widths from 51 mm to 102 mm
• Supports loaded samples up to 60 kg
• Allows test cycle setting up to 9999 times
• Performs repeated lifting at 1 cycle per second
• Provides simple cycle setting, Run, Reset and Emergency Stop operation
• Includes emergency stop function for immediate halt
• Provides visible test operation through the protective door

This configuration allows laboratories to perform standardized handle strength testing efficiently while maintaining safe operation.

General Configuration

Test Parameters

Testing Principle

The handle strength test evaluates the ability of cookware and slow cooker handles to withstand repeated lifting under loaded conditions.

Before testing, the sample is weighed and filled with steel balls to reach three times the standard weight according to the test procedure. The loaded appliance is then fixed on the equipment and repeatedly lifted by its handles to a height greater than 305 mm at a rate of 1 cycle per second.

This repeated mechanical stress helps determine whether the handles and their attachment points maintain structural integrity without deformation, cracking, loosening or detachment. The test is particularly important for appliances containing hot liquids, where handle failure may create safety risks during handling.

Test Result Evaluation

After the repeated lifting test, the handle assembly and connection points should be inspected for visible damage, loosening, cracking, deformation or detachment. The cooker body should also be checked to confirm whether the handle mounting area remains structurally secure after the preset number of lifting cycles.

For formal testing, the final judgment should follow the applicable UL 1026 requirement, customer test procedure and laboratory acceptance criteria.

Test Workflow

1. Read the relevant sections of UL 1026 and the operation manual before testing.
2. Measure the weight of the empty slow cooker sample.
3. Fill the sample with steel balls to reach three times the standard weight.
4. Secure the loaded sample onto the equipment fixture.
5. Close the protective door.
6. Set the desired number of test cycles on the control panel.
7. Press the “Run” button to start automatic testing.
8. The equipment automatically stops once the preset number of cycles is completed.
9. Open the door and inspect the sample handles for damage, deformation or loosening.
10. Record test results and sample condition.
11. Remove the sample and reset the counter if needed for the next test.

Operation Notes and Safety Requirements

To ensure safe and reliable test results, the following practices should be observed:

• Do not open the equipment door while the machine is in operation.
• The operating speed has been factory-set. Do not adjust the frequency converter inside the electrical cabinet.
• If the sample handle shows signs of failure or damage during testing, press the Emergency Stop button immediately.
• Ensure that the sample is properly secured before starting the test.
• Verify that the total loaded weight does not exceed the equipment’s maximum capacity of 60 kg.
• Check the handle width and fixture position before each test series.
• Perform regular inspection of the lifting mechanism, sample fixture, cycle counter and safety protection functions.
