20、 iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body inter

21、ested 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 take part in the work. ISO collaborates closely with the International Electrotechnical

22、 Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the te

23、chnical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IS

24、O shall not be held responsible for identifying any or all such patent rights. ISO 1716 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 1, Fire initiation and growth. This third edition cancels and replaces the second edition (ISO 1716:2002), which has been technically re

25、vised.

26、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 as

27、sessment 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 ins

28、tructions at all times. 1 Scope 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 p

29、recision of the test method is given in Annex B. 2 Normative references The following referenced documents are indispensable for the application of this document.

39、 per unit area NOTE The surface density is expressed in kilograms per square metre. 4 Principle In this test, a test specimen of specified mass is burned under standardized conditions, at constant volume, in an atmosphere of oxygen, in a bomb calorimeter calibrated by combustion of certified benzoic

40、 acid. The heat 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 i

41、t does not take into account any inherent variability of the product. 5 Test apparatus 5.1 General The test apparatus (bomb calorimeter) shall be as illustrated in Figure 1, and as detailed in 5.2 to 5.5. Additional equipment shall be in accordance with 5.6 to 5.11. 5.2 Calorimetric bomb, constructe

42、d with the following characteristics The calorimetric bomb shall be constructed as follows: a) volume: (300 50) ml; b) mass not greater than 3,25 kg; c) casing thickness at least 1/10 of the inner diameter of the body. The lid is intended to receive the crucible and the electric firing device. The l

43、id, including any seals, shall be capable of withstanding an internal pressure of 21 MPa. NOTE These conditions define a bomb in which 1 g of coal under an initial oxygen pressure no greater than 3 MPa (pressure gauge method) is able to withstand, with a sufficient coefficient of safety, the maximum

44、 amount of pressure created under combustion, without a need for a calorimetric bomb of overlarge mass. The inner surface of the bomb shall be resistant to attack by products of combustion and, even when “fuels” rich in sulfur are used, it shall resist pitting and inter-crystalline corrosion by acid

45、s produced during combustion. 5.3 Calorimeter 5.3.1 Jacket, consisting of a double-walled container, which is thermally insulated together with an insulated lid. The jacket is filled with water. The dimensions of the jacket shall be such that there is at least 10 mm space around the calorimetric ves

46、sel. The calorimetric vessel shall be supported on an as small as possible area of non-conducting material, preferably a 3-point support. For an adiabatic calorimeter system, a heater and thermometer system shall be incorporated into the vessel such that the water temperature in the jacket is mainta

47、ined at the same temperature as the water in the calorimetric vessel. For an isothermal calorimeter system, the temperature of the water in the jacket shall be kept constant. For an isothermal calorimeter, the necessary corrections shall be made (see 9.2). BS EN ISO 1716:2010ISO 1716:2010(E) 4 ISO 2

48、010 All rights reserved5.3.2 Calorimetric vessel, consisting of a polished metal container designed to accommodate the bomb. The dimensions shall be such that the bomb can be immersed in water (see 8.3.7). 5.3.3 Stirrer, driven by a constant-speed motor. To prevent the transfer of heat to and from t

49、he calorimeter, the driving shaft of the stirrer shall have a thermally insulated section in a gasket between the jacket lid and the jacket. A magnetic stirring device with a similar performance is an acceptable alternative. 5.4 Temperature measuring device, capable of giving a resolution of 0,005 K. When using a mercury thermometer, this shall have at least 0,01 K graduations with a device, e.g. a lens, for taking readings to within 0,005 K. A mechanical vibrator shall also be used to gently tap the thermometer to ensure that the mercu
