This European Standard, a part of the BS EN 1995 Eurocode series, deals with the design of timber structures for the accidental situation of fire exposure and is intended to be used in conjunction with BS EN 1995-1-1 and BS EN 1991-1-2:2002. This Eurocode applies to the design of buildings and civil engineering works in timber (solid timber, sawn, planed or in pole form, glued laminated timber or wood-based structural products e.g. LVL) or wood-based panels jointed together with adhesives or mechanical fasteners.
It complies with the principles and requirements for the safety and serviceability of structures, and the basis of design and verification that are given in BS EN 1990:2002.
It covers the requirements for mechanical resistance, serviceability, durability and fire resistance of timber structures.
The National Annex for this standard is also available.
BS EN 1995-1-2 only identifies differences from, or supplements normal temperature design. It deals only with passive methods of fire protection. Active methods are not covered.
BS EN 1995-1-2 applies to building structures that are required to fulfil certain functions when exposed to fire, in terms of:
- Avoiding premature collapse of the structure (load-bearing function)
- Limiting fire spread (flames, hot gases, excessive heat) beyond designated areas (separating function)
This European Standard gives principles and application rules for designing structures for specified requirements in respect of the aforementioned functions and levels of performance. It applies to structures or parts of structures that are within the scope of BS EN 1995-1-1 and are designed accordingly.
The methods given in this standard are applicable to all products covered by product standards made reference to in this part of BS EN 1995.
This European Standard describes the principles, requirements and rules for the structural design of buildings exposed to fire, including the following aspects:
- Safety requirements
- Design procedure
- Design aids
BS EN 1995-1-2 is intended for clients (e.g. for the formulation of their specific requirements), designers, contractors and relevant authorities.
The National Annex for this standard is also available.
Second Generation of EN Eurocode 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.
