Full Notch Creep Tester

This testing machine is used to test the environmental stress cracking performance of plastic materials.  The equipment features touchscreen operation, weight loading, and ensures independent operation of each workstation, uniform temperature distribution, and stable and consistent test results. In addition, a water level monitoring function alerts the operator when the water level is too low.

Applications

Test Procedures

1. Pre-test preparation

Check that the instrument's power supply, heating system, and loading mechanism are functioning correctly. Calibrate the temperature and load sensors. Clean the test chamber and fixtures of any debris. Ensure that there is sufficient high-temperature medium (such as heat transfer oil).

2. Sample preparation and installation

Prepare samples with full notches according to the standard, and record basic information such as sample dimensions and notch parameters. Fix the sample onto the special fixture, ensuring that the notch direction is consistent with the force direction, and that the clamping force of the fixture is uniform to prevent sample misalignment.

3. Parameter setting

Set the test temperature, constant load value, and holding time (or fracture termination condition) through the control panel. Set the data acquisition frequency. After confirming that the parameters meet the test standard (e.g., ISO 16770), save the settings.

4. Starting the test

Close the test chamber door, start the heating system, and after the chamber temperature stabilizes to the set value and is maintained for a period of time, start the loading program. The instrument will automatically apply a constant load and start timing, recording creep deformation data in real time.

5. Test monitoring

During operation, monitor the temperature and load stability, observe the sample deformation and crack propagation, and promptly handle any abnormal alarms to ensure continuous testing.

6.Test completion and cleaning

After the sample fractures or reaches the set duration, the instrument automatically unloads and shuts down. After the test chamber cools down to room temperature, open the chamber door, remove the sample, and record data such as fracture time and deformation amount. Clean the fixtures and test chamber, turn off the instrument power, and prepare the test report.

Maintenance Information

(1)Clean the testing area, sample holders, and notched fixtures regularly to prevent debris accumulation.

(2)Inspect and lubricate moving parts, guides, and mechanical components to ensure smooth operation.

(3)Check load cells, sensors, and electrical connections periodically for proper function and measurement accuracy.

(4)Calibrate the machine regularly according to manufacturer guidelines to maintain reliable creep testing results.

(5)Replace worn or damaged parts, such as clamps, fixtures, or mechanical components, promptly.

(6)Update software or firmware as recommended to ensure proper operation and accurate data logging.

(7)Maintain detailed records of maintenance, inspections, and calibrations to ensure consistent performance.

FAQ

1. What is a Full Notch Creep Tester used for?

It measures the creep resistance and time-to-failure of notched polymer and plastic samples under constant stress.

2. How does the tester operate?

The sample with a notch is subjected to a controlled load, and deformation over time is recorded until failure or a set endpoint.

3. What types of materials can be tested?

Commonly used for plastics, polymers, and composite materials that require evaluation of long-term stress performance.

4. How is test data recorded and analyzed?

Deformation, strain, and time-to-failure are recorded digitally, displayed on the interface, and can be exported for further analysis.

5. What maintenance is required for the tester?

Routine cleaning, lubrication of moving parts, calibration checks, inspection of load cells and fixtures, and timely replacement of worn components.
