1.1.2 Standar yang Berlaku

The LS-B17 Insulating Sleeves of Plug Pins Abnormal Heat Resistance Test Device strictly complies with GB/T 2099.1-2021″Plugs and Sockets for Household and Similar Purposes—Part 1: General Requirements,” specifically Clause 28.1.3 and Figure 40 (IEC 60884-1(2022, Pasal 28.1.3, Gambar 43).

It is primarily used in electrical product quality inspection laboratories, the quality control departments of manufacturers of electrical accessories such as plugs and sockets, third-party testing organizations, and for import and export product inspections.

1.2 Verifikasi Konfigurasi Peralatan

1.2.1 Membongkar

When unpacking the device, handle it gently and avoid using sharp tools that could scratch the outer casing. After unpacking, first inspect the exterior of the device to ensure there is no visible deformation or dents, and that the buttons are not damaged or loose. If you notice any abnormalities with the device or its accessories, do not power it on. Please contact us immediately.

2. Tindakan Pencegahan Keamanan

2.1 Keamanan Listrik

Sebelum menyambungkan kabel daya, pastikan tegangan suplai adalah AC 220V ±10% dan frekuensinya 50 Hz atau 60 Hz. Anda harus menggunakan stopkontak tiga cabang dengan ground pelindung, dan resistansi ground pelindung harus ≤4 Ω. Jangan pernah memotong atau melepaskan kabel ground pelindung, karena hal itu menimbulkan risiko sengatan listrik.

2.2 Keselamatan Lingkungan

Do not use this equipment in environments with flammable or explosive materials, strong electromagnetic interference, high temperatures and humidity, or excessive dust levels. Place the equipment on a level, stable surface, leaving a minimum of 0.5 m of clearance around it for operation. Operating environment: Temperature 5°C to 35°C, humidity ≤65% RH.

2.3 Prosedur Operasional

During testing, do not extend any body parts or foreign objects into the equipment’s test area to prevent burns or accidents; do not disassemble equipment components without authorization; set the test temperature strictly in accordance with standard requirements, and do not conduct tests at non-standard temperatures without authorization.

4. Insulation Sleeve for Plugs—Abnormal Heat Resistance Test

4.1 Persiapan Sampel

Select brand-new, original plugs and prongs with intact insulation sheaths that show no cracks or signs of aging; exclude test specimens with damaged sheaths or deformed prongs.

4.2 Mengatur Parameter dan Memulai Pengujian

Prosedur	Note
①	Set the test duration and temperature according to the standard. For plugs with a rated current of 2.5 A, the test temperature is 120°C; for plugs with a higher rated current, the test temperature is 180°C. The test duration is 3 hours (set to 180 minutes on the equipment).
②	Without loading a specimen, press the “Start Test” button to activate the heating function. This step is used solely to bring the test apparatus up to the test temperature; it takes approximately 40 minutes for the test apparatus to reach 180°C.
③	After heating the unit under no-load conditions to the set temperature and maintaining that temperature for 10 minutes, insert the test specimen into the testing apparatus, press the reset button, and restart the timer.
④	When the test duration reaches the set time, the test stops automatically and the heating function turns off. Remove the specimen from the test apparatus, allow it to cool to room temperature, and then hold it at room temperature for at least 4 hours.

4.3 Prosedur Pasca-Uji

4.3.1 Test Specimen Pin

The insulating sheath of the test specimen plug shall comply with the provisions of Clause 30 of the reference standard; however, the impact test and visual inspection shall be conducted at ambient temperature. During the visual inspection, no cracks visible to the naked eye—with or without corrective lenses—shall be present, and any dimensional changes in the insulating sheath shall not be sufficient to compromise protection against accidental contact.

4.3.2 Pengaturan Tes

After all tests are completed, the test apparatus will still be at a high temperature; routine maintenance may not be performed until it has cooled to room temperature.

5. Pemeliharaan dan Perawatan Peralatan Harian

5.1 Perawatan Harian Setelah Pemutusan Daya

Remove dust and test residue from the surface of the equipment, and ensure that the sample mounting holes are clean and free of foreign objects.

5.2 Pemeliharaan Selama Penyimpanan Jangka Panjang

After powering down and cleaning the equipment, cover the entire unit with a dust cover and store it in a dry, well-ventilated warehouse; power it on for 30 minutes each month to prevent components from becoming damaged due to moisture.

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.
