BS EN 1993-1-2 describes the principles, requirements and rules for the structural design of steel buildings exposed to fire, including the following aspects:
- Design of steel structures for accidental exposure to fire
- Passive methods of fire protection
- Applies to steel structures that are required to fulfil this load bearing function, avoiding premature collapse due to fire
- Gives principles and application rules for designing structures for specified requirements in respect of the load bearing function and the levels of performance.
The methods given are applicable to any steel grade for which material properties at elevated temperatures are available, based on harmonized European standards.

The second generation of EN Eurocode standards is expected to be published between 2023 and 2026. These documents are being published as soon as they are available, to enable users to prepare for the transition from the first generation to second generation of Eurocodes. As set out in the National foreword of the BS EN second generation Eurocodes, UK adoptions of the first generation of Eurocodes will be withdrawn by BSI on 30 March 2028. That means there is a period of coexistence between 2023 and 2028 during which both first and second generation Eurocodes are available.
Until 30 March 2028, the first generation documents should be considered as the applicable standards for buildings and civil engineering works constructed in the UK unless otherwise specified by the relevant authority or in the specification for a particular project. While the use of provisions in second generation Eurocodes in conjunction with first generation Eurocodes is not precluded, it should be undertaken with care and should only be done when users are satisfied that it will not result in a lower level of reliability than the minimum level set in the first generation Eurocodes and associated UK National Annexes.
