WARNING — The attention of all persons concerned with managing and carrying out this test is drawn
to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful
gases may be evolved during the test. Operational hazards may also arise during the testing of
specimens, such as the possibility of an explosion, and during the disposal of test residues.
WARNING — An assessment of all the 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 instructions at all times.
This International Standard specifies a method for the determination of the gross heat of combustion (QPCS) of
products at constant volume in a bomb calorimeter.
Annex A describes the calculation of the net heat of combustion (QPCI) when required.
Information on the precision of the test method is given in Annex B.
