Non-combustible material
Approved document J, Combustion appliances and fuel storage systems defines ‘non-combustible materials’ as:
‘…the highest level of reaction to fire performance. Non-combustible materials include:
- Any material which when tested to BS 476-11:1982 (2007) does not flame nor cause any rise in temperature on either the centre (specimen) or furnace thermocouples.
- Products classified as non-combustible in tests following the procedures in BS 476-4:1970 (2007).
- Any material classified as class A1 in accordance with BS EN 13501-1:2002 Fire classification of construction products and building elements. Classification using data from reaction to fire tests.
Typical examples of such materials to be found in buildings include totally inorganic materials such as concrete, fired clay, ceramics, metals, plaster and masonry containing not more than 1% by weight or volume of organic material. (Use in buildings of combustible metals such as magnesium–aluminium alloys should be assessed in each individual case.)'
