BS EN 1366-4:2021

This part of the EN 1366 series specifies a method for determining the fire resistance of linear joint seals based on their intended end use. Perimeter seals of curtain walling are excluded from this part of the EN 1366 series.This document is intended to be used in conjunction with EN1363?1.The following tests are included in this document: no mechanically induced movement; mechanically induced movement. Tests in accordance with this part of the EN 1366 series are not intended to provide quantitative information on the rate of leakage of smoke and/or hot gases, or on the transmission or generation of fumes. Such phenomena are only noted in the test report in describing the general behaviour of test specimens during the test.The load-bearing capacity of a linear joint seal is not addressed in this part of the EN 1366 series. No information can be implied by the test concerning the influence of the inclusion of linear joint seals on the loadbearing capacity of the separating element.
