Fire resistance tests — Door and shutter assemblies — Part 4: Linear joint fire seal materials used to seal the gap between a fire door frame and the supporting construction

This document specifies a standard test methodology and resulting field of direct application which are applicable to linear joint fire seal materials used to seal around fire door sets which have been tested in accordance with ISO 3008‑1. The test methodology described in this document uses a smaller-scale fire resistance furnace than that prescribed in ISO 3008‑1.

Introduction
This fire test method provides a methodology for testing linear joint fire seal materials intended to be
used to seal the ‘linear joint gap’ between a fire door frame and the supporting construction.
This test methodology is only appropriate for the evaluation of alternate linear joint fire seal materials
used to seal the gap between a fire door frame and the supporting construction, if:
a) the fire door frame, doors and supporting construction have already been successfully tested
according to ISO 3008-1 and the gap between the door frame and the supporting construction does
not exceed 6 mm, provided the door and frame assembly does not permit the penetration of a gap
gauge, as specified in ISO 834-1:1999, 8.4.2; or
b) the fire door frame, doors and supporting construction have already been successfully tested
according to ISO 3008-1 and during the full-scale fire resistance test, deflection of the supporting
construction and the fire door frame was found to be less than 100 mm.

Part 4:

CAUTION — The attention of all persons concerned with managing and carrying out this
fire-resistance test is drawn to the fact that fire testing can be hazardous and that there is a
possibility of toxic and/or harmful smoke and gases evolving during the test. Mechanical and
operational hazards can also arise during the construction of the test elements or structures,
their testing and the disposal of test residues.
An assessment of all potential hazards and risks to health shall be made and safety precautions
shall be identified and provided. Written safety instructions shall be issued. Appropriate
training shall be given to relevant personnel. Laboratory personnel shall ensure that they follow
written safety instructions at all times.
