Introduction
The purpose of this test is to measure the ability of a representative specimen of a stair or a part of it to
maintain its loadbearing capacity when exposed to fire according to EN 1363-1.
Caution
The attention of all persons concerned with managing and carrying out this fire resistance test EN 1365-6 is
drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic and/or harmful
smoke and gases can be 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.
An assessment of all potential hazards and risks to health should be made and safety precautions should be
identified and provided. Written safety instructions should be issued. Appropriate training should be given to
relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times.
