Reaction to fire

Measuring reaction to fire

Exova Warringtonfire is a recognised leader in the evaluation of material and system behaviour to national and international fire safety standards. We offer extensive knowledge and experience in reaction to fire testing and physical behaviour, system performance and compliance with all regulations and codes. We respect your confidentiality and ensure that all work is conducted in a highly restricted environment.

Reaction to fire testing

The behaviour of a burning object in a developing fire will have an impact on how easy it is for people to escape from the scene. Even when reaction to fire testing is not required under the regulations, a relevant insurer or authority may request improvements to fire performance, for which testing is required.

To monitor the reaction of materials we conduct tests to evaluate ignition, flame spread, heat release, smoke generation and toxicity. As the leading authority in our field, our reaction to fire testing services help to not only to improve a manufacturer’s knowledge of a product, but to provide a competitive advantage by demonstrating the product’s superior reaction to fire qualities.

Reaction to fire test procedures

Exova Warringtonfire offers reaction to fire testing across all sectors of industry, including construction, rail, marine, automotive, defence and aerospace. A small selection of key tests that we perform include:
