2. Tindakan Pencegahan Keamanan

During high-temperature testing, temperatures may reach up to 200°C. When opening the door to remove or place test specimens, wear heat-resistant gloves; do not touch the inner chamber, blades, weights, or fixtures with bare hands to prevent burns.

Weights are heavy metal objects; handle them gently. Do not throw or stack them. The blades are sharp; be careful of the cutting edges when installing or replacing test specimens to avoid cutting your hands. When moving the entire press fixture, lift it steadily to prevent the blades from causing scratches.

4. High-Temperature Pressure Test of the Insulation Sheath

4.1 Preparation of Specimens and Apparatus

Rectangular blades are used for round-pin tests; circular blades are used for other pin tests. Refer to Section 3.1 to position the specimen correctly.

4.2 Prosedur Uji

Set the high-temperature chamber to 200°C and allow it to stabilize at the target temperature. Place the test setup, along with the test specimen mounted in its normal position, in the high-temperature chamber for 2 hours.

Next, remove the test apparatus and the specimen, detach the specimen from the apparatus, and immerse it in cold water within 10 seconds to cool it.

4.3 Evaluasi Hasil Tes

Measure the thickness of the insulating material at the indentation point; the reduction in thickness compared to the original measurement at the start of the test should not exceed 50 percent.

4.4 Post-Test Procedures

4.4.1 Reset Perangkat

After the test is complete, remove the weights and blades from the test rig bracket. Do not allow the weights and blades to remain suspended on the test rig for extended periods when the test is not in progress.

4.4.2 Persiapan Sampel

Pisahkan sampel yang lulus dan gagal dalam pengujian, beri label dengan jelas, dan hindari kebingungan.

5. Pemeliharaan dan Perawatan Peralatan Harian

5.1 Daily Maintenance After Shutdown

At the end of each day’s testing, clean dust and sample debris from the equipment surfaces, and keep the chucks and slide rails clean and free of debris; check that the blades are not deformed.

5.2 Pemeliharaan Selama Penyimpanan Jangka Panjang

After routine maintenance is complete, apply a neutral rust-preventive oil to the test apparatus, blades, weights, and other components to prevent rust; cover the entire unit with a dust cover and store it in a dry, well-ventilated warehouse.

5.3 Persyaratan Interval Kalibrasi

Untuk memastikan akurasi pengukuran dan keandalan operasional peralatan, disarankan agar peralatan tersebut secara berkala dikirim ke laboratorium metrologi pihak ketiga yang berkualifikasi untuk kalibrasi. Interval kalibrasi yang disarankan adalah 12 bulan. Pengguna dapat menentukan interval kalibrasi spesifik berdasarkan frekuensi penggunaan, kondisi lingkungan, dan persyaratan sistem mutu.
