This International Standard specifies a method of determining the fire resistance of non-load-bearing separating elements made of fibre reinforced plastics (FRP) when exposed to heating on one face.

It is applicable to FRP products for which the end-use application is smaller than the full-scale fire test specimen specified in ISO 834-1. Fire barriers in transportation applications are a common example, since the end-use dimensions of the barrier products are often smaller than those specified in ISO 834-1.

This test is, in general, applicable to FRP products which have an essentially flat surface and can have stiffening members. This includes sandwich-panel-type structures in which the skins consist of FRP.

CAUTION — The attention of all persons concerned with managing and carrying out this fire-resistance test is drawn to the fact that fire testing is hazardous and there is a possibility of toxic and/or harmful smoke and gases being evolved during the test. Mechanical and operational hazards can also arise during the construction of the test elements or structures, their testing and disposal of test residues.

It is essential that an assessment of all potential hazards and risks to health is made and safety precautions are identified and provided. It is also essential that written safety instructions are issued, that appropriate training is given to relevant personnel and that laboratory personnel ensure that they follow written safety instructions at all times.
