6、 Sample production

1. Sample size: (100 × 100 × 100) mm ³;

2. When the insulation material (product) has a covering layer, the covering layer should be removed when preparing the sample;

3. When the thickness of the insulation material (product) is less than 100mm, the test piece should be prepared by stacking, and the position where the temperature measuring thermocouple is placed in the center of the test piece should not be at the joint of the test piece.

7、 Determination of smoldering performance test results——Appendix D Insulation Material Combustion Performance Tester DB11/381

During the 24-hour test period, if the center temperature of the sample is not greater than 600 ℃, the test result is judged as qualified;

If the center temperature of the sample is greater than 600 ℃, the test result is judged as unqualified.
