ÖNORM EN 1999-1-2|Fire design

EN 1999-1-2 deals with the design of aluminium structures for the accidental situation of fire exposure and is intended to be used in conjunction with
EN 1999-1-1 and EN 1991-1-2.

This part 1-2 only identifies differences from, or supplements to, normal temperature design. EN 1999-1-2 deals only with passive methods of fire protection. Active methods are not covered.

EN 1999-1-2 applies to aluminium structures that are required to fulfil load bearing function if exposed to fire, in terms of avoiding premature collapse of the structure. It gives principles and application rules for designing structures for specified requirements in respect of the load bearing function and the levels of performance.

The aluminium alloy properties given in EN 1999-1-2 apply to the following aluminium alloys:

  • EN AW-5052 – 0 and H34
  • EN AW-5454 – 0 and H32
  • EN AW-6063 – T6
  • EN AW-5083 – 0 and H113
  • EN AW-6061 – T6
  • EN AW-6082 – T6

The methods given in EN 1999-1-2 are applicable to any aluminium alloy based on harmonised European standards for which material properties at elevated temperatures are available.
