The most demanding third party certification scheme within the industry is
Certifire, set up jointly by Warrington Fire Research and British Standards Institution.
It is the acknowledged certification authority for passive fire protection products.
Specifiers choosing materials from the Certifire Register of Approved Products can be secure in the
knowledge that these have been subjected to the most rigorous independent testing, and have
worldwide recognition. All Sealmaster intumescent fire seals have been tested and approved by
Certifire to BS476 part 22 on full-sized doorsets. The testing was carried out on doorsets
manufactured to the guidlines of HTM 58 which enables performance assessments to be made independently of the
variations that can occur due to fire door set designs and configurations.
The smoke sealing elements of Sealmaster's fire and smoke seals have been tested and approved by Certifire
for smoke leakage to BS476 part 31.1 as well as an additional Certifire requirement of 100,000 door
operation cycles that ensures performance is not degraded by daily use. These certifications apply
to latched or unlatched doors or single and double leaf design and with a single or double action.
All products are manufactured under a ISO 9001 Quality Management System certified by SGS Yarsley.
