EN ISO 1182 / EN 1182 Test Methods for Non-Combustibility of Building Materials
Non-combustible materials refer to those who do nor catch fire, smoke, or burn when they are exposed to flame or high temperature. It includes all natural materials (stones, sands, clays,etc.) as well as artificially made inorganic materials and metal materials used in construction.
Attention --- EN ISO 1182 / EN 1182 Test Methods for Non-Combustibility of Building Materials
1. Temperature rise
In the ℃ unit, the furnace temperature rise and sample temperature rise of each sample were calculated by the following formula.
a) Temperature rise in the furnace △Tf=Tf(max)-Tf(final)
b) Temperature rise of the sample center △Tc=Tc(max)-Tc(final)
c) Temperature rise of the sample surface △Ts=Ts(max)-Ts(final)
T(max) is the highest temperature and T(final) is the final temperature at the end of the test
The arithmetic mean of the furnace temperature rise, the sample center temperature rise, and the sample surface temperature rise for each sample was recorded and calculated.
The flame records the sum of the duration of the flames of each sample, in units of S.
Record and calculate the arithmetic mean of the duration of the flame for each sample.
3. Quality losing
The mass loss of each sample was recorded and calculated as percentage of the initial mass of the sample.
Record and calculate the arithmetic mean of the mass loss for each sample.
Assessment of results --- EN ISO 1182 / EN 1182 Test Methods for Non-Combustibility of Building Materials
According to EN ISO 1182, the “flammability” or “incombustibility” of the material is assessed. The assessment is based on the following:
The average temperature rise in the furnace should not exceed 50℃, and the average duration of the calculated continuous flame should not exceed 20s.
After cooling, the average mass loss should not exceed 50% of the average initial mass.
