 Non-inflammability test
|
| - Test standard: GB/T 5464-1999 (idt ISO 1182) |
| - Test facility: Extension performance test equipment, balance, stopwatch |
| - Test equipment: The test is carried out only for 6mm sample based on GB/T 5464-1999. |
| - Condition control: Controlled for 24 hours in a ventilation dry box with 60±5℃ temperature |
| Test result : |
| - Average temperature rise in furnace: 2.2 ℃ |
| - Average combustion time: 0 s |
| - Average weight loss rate: 45.1% |
| Conclusion of test: Based on the criterion of material combustion performance within GB 8624-1997, |
| determine that combustion performance of sample received is A-grade. |
| Exterior: Surface of decoration plate is uniform and smooth without Pinhole, wrinkle and projected string. |
| Surface density : |
| - Reference standard: CECS 95:97 |
| - Sample size: 200mm X 100mm X 6mm 6pcs |
| - test facility: Steel yardstick, balance |
| - Condition control: Control for 24 hours within 23±2℃ temperature and 50±5℃ relative humidity |
| - Test result: 1.03 g/cm3 |
| Absorptance and quantity of soluble material content |
| - Reference standard: CECS 95:97 |
| - Sample size: 80mm X 80mm X 6mm 6pcs |
| - Test facility: balance, dry box |
| - Test process: |
1) Dry for 24 hours in 100~105℃ dry box and change the internal temperature for cooling with G1
intermediate sample weight |
| 2) Soak a sample in water for 24 hours, and remove water with G2 intermediate sample weight |
| 3) Dry for 24 hours in 100~105℃ dry box, and cool with internal temperature with G3 intermediate sample weight after change |
| Calculation formula : Each sample absorptance = (G2-G1)/G1X100% |
| Each sample soluble material quantity = (G1-G3)/G1X100% |
| Test result: 29.1 % for absorptance; 5.3 % for soluble material quantity |
| Bending strength |

| Freezing and thawing circulation |
| - Reference standard: CECS 95:97 |
| - Sample size: 200mm X 100mm X 6mm 6pcs |
| - Test facility: low temperature box |
| - Test process: One circulation indicates melting sample for 60 min. in 20±5℃ air |
| after cooling for 90 min. in 20±2℃. This process is repeated. |
| - Test result: No case of having layers or crack from the result of 25 experiments |
| Formaldehyde discharge quantity |
| - Test standard: GB18580-2001 |
| - Sample size: 150mm X 50mm X 6mm 10pcs |
| - Test facility: Spectrum photometer |
| - Formaldehyde discharge quantity : Indication of limit quantity: E1 limited value: ≤ 1.5mg/L |
| Indication of limit quantity: E2 limited value: ≤ 5.0mg/L |
| - Test result: Satisfying E1 grade requirement in 0.09 mg/L, GB18580-2001 |
