2.2.2 Kontraindikasi Lingkungan

Lingkungan dengan medan magnet yang kuat dan medan listrik yang kuat;

Lingkungan yang mengandung gas atau cairan korosif;

Area dengan debu yang mudah terbakar dan meledak, serta area yang mengandung bahan berbahaya;

Lingkungan dengan banyak debu, suhu dan kelembapan tinggi, serta sinar matahari langsung.

2.3 Keselamatan Operasional

Operator harus memahami buku panduan instruksi;

Wear safety goggles during testing; do not under any circumstances extend your hands or head into the area where the steel ball strikes;

The test area must be free of debris; unauthorized personnel are prohibited from approaching. Ensure there is sufficient operating space to prevent accidental injury;

Do not leave the electromagnet powered on for extended periods to prevent the coil from burning out.

4. Persiapan Sebelum Ujian

4.1 Mempersiapkan Lingkungan

Place the equipment on a level surface and level the frame; clean the test bench to ensure that the sample support surface is rigid and flat.

4.2 Persiapan Sampel

The specimen must be securely clamped in accordance with the standard; shaking is prohibited. Determine the impact location (vulnerable surfaces or areas prone to impact). The specimen’s surface must be clean and free of damage that could affect the test.

4.3 Parameter Verification

Confirm the impact mode: drop test/swing test; confirm the impact height: 1.3 meters, for example (or refer to the applicable standard).

5. Steel Ball Impact Test

5.1 Vertical Impact Test with a Steel Ball (Equipment must be powered on)

5.1.1 Contoh Penempatan

Place the sample on the rigid support surface directly beneath the steel ball; adjust its position so that the impact point aligns with the target test location.

5.1.2 Impact Height Adjustment

Adjust the height of the steel ball mounting bracket, use a steel ruler to verify that the free fall height is 1.3 meters, and tighten the bracket screws.

5.1.3 Placement of Steel Balls

Connect the power cord and turn on the main unit’s power switch; place the steel ball directly beneath the electromagnet and make sure it is securely attached.

5.1.4 Impact Execution

Evacuate all unauthorized personnel to a safe area; press the release button to de-energize the electromagnet and release the steel ball, thereby completing the vertical impact test. If the steel ball bounces back, catch it to prevent a secondary impact.

If no further vertical impact tests are required, turn off the power switch on the equipment.

5.1.5 Verification of Test Results

Observe the sample’s appearance, structure, protective performance, and other characteristics in accordance with the standard requirements.

5.2 Horizontal Impact Test with a Pendulum Steel Ball (No power required for the equipment)

5.2.1 Contoh Penempatan

Place the sample within the swing path of the oscillating steel ball.

5.2.2 Steel Rope Adjustment

Adjust the length of the steel cable attached to the pendulum ball to ensure that the ball strikes the target point precisely when it falls.

5.2.3 Steel Ball Height Adjustment

Lift the pendulum so that the point where it falls is 1.3 meters vertically above the impact point; keep the steel cable taut, with no slack.

5.2.4 Impact Enforcement

Gently release the steel ball; it will strike the specimen along the swing path, completing the horizontal impact test. If the steel ball rebounds, catch it to prevent a secondary impact.

5.2.5 Verification of Test Results

Observe the sample’s appearance, structure, protective performance, and other characteristics in accordance with the standard requirements.

6. Pemeliharaan dan Perawatan Peralatan Harian

6.1 Routine Maintenance (After Each Test)

Store the steel ball and steel cable separately and securely; return the steel ball mounting bracket to its original height; remove the test specimen; wipe down the equipment surface, support platform, and control panel with an antistatic, dry cloth; check that the steel ball is not deformed and the steel cable shows no signs of wear; confirm that the electromagnet is not overheating and does not emit any unusual odors.

6.2 Regular Maintenance (Once a Month)

Apply grease or rust-preventative oil to the steel balls and electromagnets to prevent rust; inspect the adjustable mounting brackets and add lubricant; tighten all loose screws and joints.

6.3 Storage and Maintenance (During Extended Periods of Non-Use)

Store in a dry, well-ventilated environment with humidity ≤ 75%; remove all steel balls and store them separately to prevent rust; turn off the main power supply and cover the equipment with a dust cover; do not subject the equipment to heavy pressure or impact.
