NON-COMBUSTIBILITY TESTING
BS EN ISO 1182:2020
WHAT IS A NON- COMBUSTIBILITY TEST?
This test identifies products that will not, or not significantly, contribute to fire, regardless of their end use.
The fire test has been developed to selected construction products which produce a very limited amount of heat and flame when exposed to temperatures of approximately 750 °C.
The test specimen shall be taken from a sample which is sufficiently large to be representative of the product and shall be cylindrical with a volume of 76 ± 8cm³ and diameter of 45+0mm and a height of ± 3mm.
For non-homogenous (e.g., layered, or composite products) – each component or layer shall be tested separately.
A minimum of 5 samples shall be tested for classification.
After conditioning the samples must be dried in an oven at 60±5°C for 20-24hr. Prior to testing each sample is weighed to an accuracy of 0.01g.
The samples are then inserted into a furnace that has been stabilised at 750 ±5°C for a minimum period of 30 min. The following data is recorded:
-
Temperature of the furnace
-
Temperature of the specimen centre and surface
-
Any sustained flaming (3s or longer)
​
The sample is then removed, allowed to cool, and weighed again. The test report will show:
​
-
Mass loss (%) of each sample.
-
Temperature rise of each sample
-
Any sustained flaming
WHAT PRODUCT CLASSIFICATIONS REQUIRE BS EN ISO 1182 TESTING?
