Fire Performance

SAS metal ceilings are tested and certified in accordance with UK and European standards.

UK Building Regulations

The Building Regulations’ ‘Approved Document B’ for fire safety sets out minimum requirements for the performance of ceilings within buildings. The requirements are either tested to UK standards (BS 476 Parts 6 and 7),  or European standards (EN 13501-1).

Our ceiling tile test results fully comply with BS 476 Parts 6 and 7. When read in conjunction, these results meet Class 0 requirements as defined in the UK Building Regulations.

Please Note The harmonised European class system will phase out the individual European countries classes over time. The national classifications do not automatically equate an equivalent in the European Class, unless they  have been tested accordingly.

European Standards (EN 13501-1)

SAS ceiling tiles have a European Class performance of:

A2-s1, d0

The first figure sets out the fire behaviour of the product, with a result ranging from A to F:

A1   Product does not contribute to fuelling the fire at any stage.

A2   Product does not significantly contribute to the fire load nor spread.

B      Product has limited lateral spread of flame with sufficiently delayed and limited heat release.

The second figure (‘s’), relates to the smoke behaviour, with three classifications:

s1  Product emits negligible smoke emissions.

s2  Product emits a limited amount  of smoke.

s3  No limitation set  for emissions.

The third figure (‘d’) relates to the volume of flaming droplets or particles, with classifications of d0-d2:

d0  Classification requires that no droplets or particles occur at any time during the test.

d1   Stipulates a minimum period of time where no flaming droplets or particles can persist.

d2  Classification does not limit the performance required.
