This is pull-off test for adhesion of coating.
This video introduces testing complying with ISO 4624: 2002 Paint and varnished - Pull-off test for adhesion. As per a requirement of the standard, tensile force is applied perpendicularly to the coated surface to be pulled off within 90 seconds at the speed of which does not exceed 1MPa/s. The force value required to pull off the coating is recorded as the test result. Pull the adhered dolly until the sample breaks and obtain the maximum force value. This maximum value is converted to MPa to calculate the breaking strength. IMADA graphing software graphs the relationship between force and time during the test to confirm whether the requirements are met. It also visualizes the load transition for fracture. In addition, with high-speed sampling of 2000 data per second, IMADA force gauge used in this test captures accurate maximum force value. Test 6 or more samples and show the average, maximum and minimum fracture strengths calculated as a result. Watch the video for test details. The tests in this standard ISO 4624: 2002 are used in R&D and quality control.

This test is to measure torque (turning force) of tightening/loosening screws for quality control.

The maximum closing force of car hood is measured by MADA force gauge and a round pad. You just push the force gauge straightly to the hood until the latch has locked, then the maximum force is indicated on the force gauge. This test is used for inspection, safety evaluation and quality control.

The maximum force required to activate the anti-pinch function of a power window is measured by a dedicated load cell and amplifier. You just set the load cell on the automotive power window frame and press the switch to raise the window, then the maximum force is indicated. This test is used for inspection, safety evaluation and quality control.

This is pullout test of a crimped connector of wire harness complying with the corresponding part of UL 486A-486B: Edition 3. In this test, our auto crimp tester keeps pulling crimped connector of wire harness for 60 sec with steady force at a constant pace to check if the connector breaks or not. If you change jigs to hold connectors, you can conduct this test for various shapes of wire connectors. This test is carried out by using "Keep mode" of our auto crimp tester which allows users to conduct durability tests easily. Also you can implement measurements complying with other standards. Please see "Related Applications" videos below.

This is pull test on crimped terminal of high-voltage wire harness complying with the corresponding part of JIS C2805:2010. The crimped terminal is continuously pulled at a certain force based on the sample size for 10 seconds. After the test, check if the connector part was NOT pulled apart. It is used for R&D and quality control.

There are 2 ways to measure the tension strength of crimped terminals, durability test and break test. The break test complying with the coresponding part of IEC 60512-16-4: 2008 requires you to determine the maximum force value when the terminal is pulled off. On the other hand, the durability test complying with the coresponding part of JIS C2805: 2010 requires you to pull the crimped terminal continuously at a certain force for 10 seconds, and check the connector part situation after the test. They are used for R&D and quality control.

This is tensile strength test of crimped wire terminals (durability test) complying with the corresponding part of JIS C2805: 2010. It is used for R&D and quality control.

This is tension strength test of crimped wire terminals (break test) complying with the corresponding part of IEC 60512-16-4: 2008. The maximum force value is measured when the terminal is pulled off for R&D and quality control.

This is the tensile strength test of wire’s crimped terminal for quality control.

Force to operate motorcycle’s brake lever is measured by a dedicated load cell and amplifier. You just mount the load cell on a brake lever, grip them together, then the operating force is indicated. The tested data can be stored in the internal memory of the force gauge. You can also check the stored data directly on the force gauge's display easily. This test is used for inspection, safety evaluation and quality control.

Force to step foot brakes is measured by a dedicated load cell and amplifier. You just mount the load cell on a foot brake, step them together, then the stepping force is indicated. This test can also be applied to accelerator pedal. This test is used for inspection, safety evaluation and quality control.

To determine the torque of a motorcycle’s accelerator, grip the motorcycle’s handlebar with a dedicated grip, and turn the handlebar. IMADA offers the dedicated testing system such as the following configuration, which can graphically visualize the relation between torque and angle. Operativity can be analyzed by comparing test results of different test speed, too. This system is utilized for quality control and R&D.

This is operability (torque-angle) test of automotive air condition knob for quality control and R&D.
