Alu Selekta has been proven to be non-combustible but when is a material deemed combustible?
Published 21 Mar 2018 in Articles
Alu Selekta has recently passed the AS1530.1 non-combustibility test.
The results indicate that the solid aluminium profile is considered to be non-combustible in accordance with Clause C1.12(e) of the BCA and permitted to be used where the BCA nominates non-combustible material.
As part of the AS 1530.1 small-scale material fire test, a small sample of Alu Selekta was immersed in a 750°C furnace.
The test method is intended to provide material property data on individual materials, not systems or composites. However, if any one layer or element of a system or product is combustible then the whole system or product is considered combustible.
There are three criteria in AS 1530.1 where a material is deemed combustible:
- The mean duration of sustained flaming, as determined in accordance with AS 1530.1 Clause 3.2, is other than zero. In summary, the material is combustible if flaming sustained for a period of 5 seconds or longer occurs at any time during the test for any of the five samples tested.
- The mean furnace thermocouple temperature rise, as determined in accordance with AS 1530.1 Clause 3.1, exceeds 50°C.
- The mean specimen surface thermocouple temperature rise, as determined in accordance with AS 1530,1 Clause 3.1, exceeds 50°C.
