Description

BS EN 1366-3 specifies a method of test and criteria for the evaluation (including field of application rules) of the ability of a penetration seal to maintain the fire resistance of a separating element at the position at which it has been penetrated by a service.

Penetration seals used to seal gaps around chimneys, air ventilation systems, fire rated ventilation ducts, fire rated service ducts, shafts and smoke extraction ducts are excluded from this standard except for mixed penetration seals.

The purpose of BS EN 1366-3 is to assess:
a) The effect of such penetrations on the integrity and insulation performance of the separating element concerned.
b) The integrity and insulation performance of the penetration seal.
c) The insulation performance of the penetrating service or services, and where necessary, the integrity failure of a service.
