Reaction to fire testing

Our experts offer a range of UKAS accredited fire behaviour tests as well as being able to devise bespoke test programmes to meet clients' particular project requirements.

We offer a suite of UKAS accredited reaction to fire tests together with classification of reaction to fire performance to BS EN 13501-1. It is also possible for us to devise bespoke test programmes to meet the needs of particular projects or products and to support research and development.

Reaction to fire relates to the combustibility and ignitability of a material i.e. its contribution to fire development and spread, rather than its ability to resist the passage of fire (which is proven by fire resistance testing). How a fire develops in the very early stages is of crucial importance to ensure safe evacuation.

Reaction to fire tests are commonly called up in codes and regulations in both the building and transport sectors. In England and Wales, the fire requirements for buildings are dealt with by Approved Document Part B of the Building Regulations.

The tests for reaction to fire tend to be smaller in scale than for fire resistance and are carried out on specific components or materials representative of end-use application for example:
  • Wall linings
  • Ceiling linings
  • External wall surfaces
  • Fire retardant treatments
  • Jointing systems
European reaction to fire tests
European reaction to fire tests include the following:
  • BS EN ISO 1182  Non-combustibility testing
  • BS EN ISO 1716  Calorific potential test
  • BS EN 13823       Single burning item
  • BS EN 11925-2    Small flame ignitability
European reaction to fire evidence is recognised across Europe in the Building Regulations of member states. A process of European harmonisation is in progress throughout Europe in support of the Construction Products Regulation (CPR). The CPR aims to reduce barriers to trade through Europe by using the CE Mark to ensure that products placed on the market in any member state have been tested and classified consistently.

Evidence obtained from test results allow products to be classified according to BS EN 13501-1: Fire Classification of Construction Products and Building Elements: Part 1: Classification using test data from reaction to fire tests. Classifications are used and accepted throughout Europe and internationally (on a case-by-case basis).
CE marking and Notified Bodies
If your product has a published harmonised technical specification document, it is likely that CE marking will be mandatory for your product. Often, if the product contains a fire retardant, it is likely that a Notified Body will need to be involved in the CE marking process.

Exova Warringtonfire is a Notified Body under the Construction Products Regulation.
