EN 1999-1-2, titled "Eurocode 9 - Design of aluminium structures - Part 1-2: Structural fire design", is a standard that focuses on the design of aluminium structures for fire exposure. It is intended to be used alongside other related standards such as EN 1999-1-1, EN 1999-1-2, EN 1999-1-3, EN 1999-1-4, and EN 1999-1-5. This standard specifically addresses the accidental situation of fire and provides principles and application rules for designing aluminium structures to meet specified requirements and levels of performance.

EN 1999-1-2 applies to aluminium structures that have a load bearing function and are within the scope of EN 1999-1-1. It gives methods that are applicable to specific aluminium alloys, listed in the standard, such as EN AW-3004, EN AW-5083, EN AW-6063, EN AW-5005, EN AW-5454, EN AW-6082, EN AW-5052, and EN AW-6061. The methods can also be applied to other aluminium alloy and temper combinations if reliable material properties at elevated temperatures are available or if simplified assumptions specified in the standard are used.

The standard also includes assumptions that need to be considered during the design process. These assumptions include the choice of the relevant design fire scenario being made by qualified personnel or guided by national regulations, and the requirement for any active and passive fire protection systems considered in the design to be adequately maintained. EN 1999-1-2 is intended to be used in conjunction with other European standards for construction products relevant to aluminium structures, as well as EN 1090-1 and EN 1090-3, which provide requirements for conformity assessment and execution of steel and aluminium structures respectively.
