Independent Laboratory • Complete Testing Equipment • Full Quality Control
We test every product by strict standards to ensure superior quality and reliable performance.
| No. | Test Item | Test Condition | Test Requirement | Test Data | Result |
| 1 | Structure Inspection | 1. Comply with wire size table2. Minimum thickness ≥ 80% of average thickness | Comply with wire size table | Refer to test record | Pass |
| 2 | Thermal Shock | Wind the sample on an iron rod of specified size, place in an aging oven at specified temperature for 1 hour, cool the sample to room temperature for at least 30 minutes, then observe the sample | No cracks on the sample surface | No cracks | Pass |
| 3 | Heat Deformation | 1. Measure sample thickness (mark measurement position)2. Place sample and test fixture in aging oven for preheating at specified temperature for 1 hour3. Place sample under pressure column of test fixture for 1 hour4. Re-measure sample thickness at the same position | 1. Sample shall not be cracked by pressure column or expose conductor2. Thickness reduction ≤ 50% | Refer to test record | Pass |
| 4 | FT2 | Apply a standard flame at a height of 125mm once | 1. Flame shall not propagate along its length2. Flame shall not spread to nearby flammable materials | Refer to test record | Pass |
