Smoke Seals

FD30 & FD60 Smoke Seals

Ambient Temperature Smoke Seals

Separate smoke seals, or combined intumescent/smoke seals (using one of the intumescent products approved in Field of Application reports FD30 (i) PAR/10321/01 Rev .D & FD60 (ii) PAR/10896/01 Rev .B), that have been tested to BS476: Part 31: Section 31.1: 1983 and shown not to leak by more than 3m³/m/hr at 25Pa may be used in conjunction with the proposed doorsets to provide smoke control.

The Orientation of the seals, door edge gaps, degree of hardware interruption, and leaf configuration must be as tested to BS476: Part 31: Section 31.1: 1983 to achieve the desired level of smoke control, unless these conflict with the intumescent seal widths and positions detailed in the above noted Field of Application reports in which case, the latter shall take precedence.

Test evidence to BS476: Part 22: 1987 shall be available to demonstrate that the smoke seals will not adversely affect the overall fire resistance of timber doorsets, when fitted in the proposed arrangements.
