The non flammability test furnace for building materials is based on the following standards:

GB/T5464-2010 :Test method for non flammability of building materials

ISO 1182 :Fire reaction testing of architectural products---Non combustible test

BS 476-4 &11

ASTM E 136

Non combustible materials refer to materials that, when heated by fire, will not ignite even if they turn red or melt; The non flammability tester for building materials is a new versionGB8624-2012Mandatory testing items required in the fire classification standards for building materials;

Test methods and requirements
1. Sample preparation: The sample should be large enough to represent the material, and special attention should be paid to non-uniform materials.
a)Five samples should be prepared for each material.
b)The sample is cylindrical with a diameter of45±2mm, high50mm±3mm, volume80cm³±5cm³
c)The sample should represent the average performance of the material as much as possible and be made according to the dimensions specified above.
d)If the thickness of the material is less than50mmThe height of the specimen specified above can be ensured by stacking the layers of the material and adjusting the thickness of each layer of material. Before the experiment, each layer of material should be placed horizontally in the sample holder, and two samples with a diameter not exceeding0.5mmThe iron wire tightly ties the layers together to eliminate air gaps between them, but significant pressure must not be applied. The arrangement of the layers should be such that the hot junction of the thermocouple at the center of the sample is located inside the material and should not be at the interlayer interface.
2. State adjustment:
The sample should be placed in60℃±5℃ Adjustment of ventilation and drying box20h～24hAnd cool it to room temperature in a drying dish before the experiment. Before the experiment, the mass of each sample should be weighed accurately to0.1g.
