This International Standard specifies a test method for determining the effective sealing capability of intumescent materials or systems in the context of sealing door-to-frame clearances in timber door assemblies. Intumescent seals extend the duration for which the gap between the leaf edge and the frame will satisfy the integrity criteria of the fire resistance test, and sealing systems can be compared using this method. The method is suitable for evaluating the efficacy of exposed intumescent sealing systems used in conjunction with timber fire resisting doors of up to 1 h fire resistance. It is not suitable for comparing concealed intumescent seals. The results can be applied to proven, single-acting, single-leaf, latched, timber door assemblies of sizes up to that given in the field of direct application.
