3.1 Sample Requirements

The housing of the test specimen must be clean, brand-new, and intact, with all components properly installed, in accordance with the product’s factory-shipped condition;

If specified in the product standard, samples must be pretreated (e.g., powered on, or simulated to mimic the operating state of moving parts); if no such specifications exist, prepare the samples under normal temperature and pressure conditions.

3.2 Equipment Commissioning

3.2.1 Powering On the Device (This step does not apply to the S model)

Turn on the two switches inside the chassis shown in the figure below.

Gambar 3

3.2.2 Installation of the Swing-Arm Impact Hammer

Select the impact hammer and pendulum arm with the required IK rating according to section 1.2.2. Install and secure the pendulum arm:

Gambar 4

Install and secure the impact hammer:

Gambar 5

If necessary, rotate the swing arm so that the direction of the impact hammer head aligns with the direction of the swing arm’s movement. After readjusting, secure the swing arm again.

3.2.3 Sample Mounting and Alignment

Determine the test surfaces: Give priority to the weakest points in the product design; if there are no specific requirements, distribute the impact points evenly across each surface, with each surface subjected to 5 impacts (no more than 3 impacts in the vicinity of the same location).

Place the sample on the test stage close to the device’s backplane, with the test surface facing the impact hammer. Adjust the height of the test stage using the height adjustment switch based on the elevation of the test point:

Gambar 6

If you have the S model, you’ll need to use the hand-crank to adjust the stage to the appropriate height:

Gambar 7

Depending on the thickness of the sample, loosen the mounting screws on the module shown in the figure below and move the entire unit:

Gambar 8

Move it so that the impact hammer just touches the test point when it hangs naturally, and then tighten the set screw:

Gambar 9

Then secure the specimen with a flexible strap to prevent the attachment points from obscuring the test surface and to ensure that the specimen does not shift during the impact.

4. IK Rating Test Procedures

4.1 Height Requirements for the Impact Hammer

The IEC 60068-2-75 (GB/T 2423.55) standard specifies the following IK ratings and drop heights:

Gambar 10

Specifically, the drop heights for IK07, IK08, IK09, IK10, dan IK11 are 400 mm, 300 mm, 200 mm, 400 mm, and 500 mm, respectively.

The height of the IK giant pendulum can be determined using the protractor shown in the figure below:

Gambar 11

The graph showing the relationship between angle and height is as follows:

Gambar 12

4.2 Impact Hammer Height Setting

Pengambilan IK10 as an example, the required drop height is 400 mm, which means the pendulum arm must be raised to an angle of 53° from the vertical—that is, the protractor should read 90° – 53° = 37°. Then, use the slider marked in the figure below to secure the pendulum arm.

Gambar 13

4.3 IK Impact Test

As shown in the figure below, turn the handle opposite the slide to release the impact hammer and perform the impact test.

Gambar 14

To prevent the impact hammer from striking repeatedly due to inertia, after the impact hammer completes a strike and rebounds, you must manually hold the impact hammer and slowly return it to its original position. Do not use your hands to directly grip the swing arm to stop it (as this can easily cause the swing arm to deform).

Adjust the position of the sample and continue conducting impact tests on the other test points until the entire test is complete.

5. Prosedur Pasca-Ujian

5.1 Equipment Shutdown and Reset

Turn off the power switch (not necessary for the S model);

If testing is not to be continued on the same day, remove the impact hammer and pendulum to prevent deformation of the pendulum, clean them, and store them separately in a safe place (avoid impact).

5.2 Sample Preparation and Observation

Visual inspection: Check the sample housing for cracks, dents, or peeling, and check whether any fasteners are loose;

Functional Testing: Power on the sample to verify that all functions are operating normally and that there are no malfunctions;

Determine whether the product meets the IK rating requirements based on the product standards, and record the test results (pass/fail).

5.3 Persiapan Lingkungan Pengujian
