The work of preparing International Sta

22、ndards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also

23、take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In

24、particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements

25、of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (se

29、erned 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 exp

30、losion, 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. L

31、aboratory personnel should ensure that they follow written instructions at all times.1 ScopeThis document specifies a method for the determination of the gross heat of combustion (QPCS) of products at constant volume in a bomb calorimeter.This method is intended to be applied to solid products.NOTE

32、Liquids can be tested with similar equipment and using conditions described in ASTM D2401, as described in IEC 610392using ISO 19283test equipment.Annex A specifies the calculation of the net heat of combustion, QPCI, when required.Information on the precision of the test method is given in Annex B.

The heat

49、 of combustion determined under these conditions is calculated on the basis of the observed temperature rise, taking account of heat loss and the latent heat of vaporization of water.This is a test method for determining an absolute value of the heat of combustion for a product and it does not take into account any inherent variability of the product.5 Test apparatusThe test apparatus (bomb calorimeter) shall be as illustrated in Figure 1, and as detailed in 5.1 to 5.4.
