Green Fire Retardants for Structural Timber


The British Standards are used to standardise the test methods used in the UK upon which the building regulations are based. They will be superseded in 2011 by the Eurocodes, although there will be a period of co-existence. Standards referred during this project are listed below:

British Standards
BS 476 Fire Tests on building materials and structures
  • Part 6: Method of test for fire propagation for products (1989)
  • Part 7: Method of test to determine the classification of the surface spread of flame of products (1997)
  • Part 10: Guide to the principles, selection, role and application of fire testing and their outputs (2009)
  • Part 20: Method for determination of the fire resistance of elements of construction (general principles) (1987)
  • Part 21: Methods for determination of the fire resistance of loadbearing elements of construction
PD 7974 Application of fire safety engineering principles to the design of buildings - Part 3: Structural response and fire spread beyond the enclosure of origin (2003)

BS 5268 Structural use of timber  - Part 2: Code of practice for permissable stress design, materials and workmanship (2002)

BS 9999:2005 Code of practice for fire safety in the design, management and use of buildings

Eurocode 5 -  Design of Timber Structures
  • BS EN 1995-1-2:2004 Part 1-2:General - Structural Fire Design
BS EN 13501-1-2:2007+A1:2009 Fire classification of construction products and building elements
  • Part 1: Classification using data from reaction to fire tests
