Fire testing

Quelfire products are tested as a system to BS EN 1366-3 (service penetration sealing solutions) or BS EN 1366-4 standards (linear gap sealing solutions). We conduct regular tests to extend our portfolio to new applications based on feedback from our customers and industry trends.

BS EN 1366-3 test standard

Service penetration seals are fire tested to the BS EN 1366-3 test standard and can then generally be classified to EN 13501-2. Such products are referred to as penetration seal systems that fall under ETAG 026 and are commonly intumescent based. This means they expand when exposed to fire to seal off the pipe or duct, preventing fire spread.

BS EN 1366-4 standard

Linear gap seals are tested to BS EN 1366-4 which assesses the capacity of a product to effectively seal a gap between two surfaces in a specific arrangement. BS EN 1366-4 can also cover timber door frames as set out in the National Annex NA: Standard Conditions for Linear Joint Seal Materials […].

BS EN fire testing is designed to replicate a flashover fire. With actual furnace temperatures being capable of exceeding 500°C within the first minute, this method is extremely onerous and aggressive. Therefore, all firestopping products must be capable of rapid expansion to ensure quick closure of the service penetration.

Both BS EN 1366-3 and BS EN 1366-4 employ a cellulosic test method to evaluate both fire integrity and insulation properties.

Product certification

Third-party certification: Our products are fire tested at third-party, accredited test laboratories.

CE marking: Most of our core products are CE marked under the Construction Products Regulation (CPR). Our CE marked product range has been fire tested to BS EN 1366-3: 2009 at Exova Warringtonfire. In addition, continuous factory production controls and external auditing by Warrington Certification are undertaken.

UKCA marking: From 31st December 2024, UKCA marking will be mandatory for products placed on the market in Great Britain. However, due to the uncertainty around this marking, we are currently staying with CE marking until further guidance and confirmation is established.

ISO 9001 Accreditation

Our products have always been subjected to the stringent quality controls of BS and EN standards.

Our complete quality management system is audited and meets the criteria of the internationally recognised ISO 90001 accreditation. All our processes are monitored and evaluated to ensure consistent results and to also ensure we are taking advantage of opportunities for improvement.
