| Notes |
1. During the single-burning item test, a 12mm thick calcium silicate board was used as the backing board for the test specimen. 2. This report does not include the smoke toxicity test specified in GB/T 20285-2006. 3. According to clause 5.2.2d) of GB/T 20284-2006, the sample adhered to a non-combustible substrate's surface with Class A combustion performance using a bonding method. 4. The results of this test are only related to the performance of the sample under specific test conditions. They should not be used as the sole basis for evaluating the potential fire hazard of the product in actual use. |
