27、ions, at constant volume, in an atmosphere of oxygen, in a bomb calorimeter calibrated by combustion of certified benzoic 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 vap
28、orisation of water. It should be noted that this is a test method for determining an absolute value of the heat of combustion for a product and does not take into account any inherent variability of the product. Safety warning So that suitable precautions are taken to safeguard health, the attention
29、 of all persons concerned in fire tests is drawn to the possibility that toxic or harmful gases may be evolved in the combustion of test specimens. In this test procedure, suitable measures should be taken to prevent harm in the event of an explosion. Licensed Copy: London South Bank University, Lon

This European Standard des
31、cribes a test method for the measurement of the gross heat of combustion (PCS). Annex A describes the calculation of the net heat of combustion (PCI) when required. Information on the precision of the test method is given in Annex B. 2 Normative references This European Standard incorporates by date
32、d or undated reference provisions from other publications. These normative references are cited at appropriate places in the text and the publications are listed hereafter. For dated references subsequent amendments to or revisions of any of these publications apply to this European Standard only wh

44、Calorimetric bomb 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 lid, including any s
45、eals, shall be capable of withstanding an internal pressure of 21 MPa. NOTEThese 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 amount of pressure
46、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 sulphur are used, it shall resist pitting and inter-crystalline corrosion by acids produced during c
47、ombustion. 4.3 Calorimeter 4.3.1 Jacket The jacket shall be 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 vessel. The calor
48、imetric vessel shall be supported on an area as small as possible 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 so that the water temperature in the jacket is maintained at the same
49、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 8.2). 4.3.2 Calorimetric vessel This shall be a polished metal container designed to accommodate the bomb. The dimensions shall be such that the bomb can be immersed in water(see 7.3 d). 4.3.3 Stirrer A stirrer driven by a constant speed motor shall be provided. To prevent the transfer of heat to and from the calorimeter,
