DIN EN ISO 1716:2010-11 EN ISO 1716:2010 (E) 5 3.13 surface densit
35、y mass 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 b
36、enzoic 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
37、 and it 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, cons
38、tructed 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.
39、 The lid, 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 m
40、aximum 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 b
41、y acids 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 calorimetr
42、ic vessel. 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
43、maintained 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). DIN EN ISO 1716:2010-11 EN ISO 1716:2
44、010 (E) 6 5.3.2 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 the calorimete
45、r, 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
46、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 mercury column does not stick. 5.5 Crucible, made of metal, such as platinum
47、, nickel, stainless steel or silica, with a flat base, 25 mm in diameter (maximum dimension if it is truncated) and 14 mm to 19 mm high. NOTE 1 The following wall thickness is recommended: metal: 1,0 mm; silica: 1,5 mm. NOTE 2 Several shapes of crucible have proved satisfactory. 5.6 Timing device, c
48、apable of recording the time elapsed to the nearest second and accurate to within 1 s in 1 h. 5.7 Electric power source, with the voltage to the firing circuit not exceeding 20 V for the firing. An ammeter shall be added to the circuit to indicate the breaking of the firing wire. A circuit breaker i
49、s a useful addition to the supply circuit. 5.8 Pressure gauge and needle-valve, attached to the oxygen-supply circuit to show the pressure in the bomb while it is being filled; this pressure shall be indicated with a resolution of 0,1 MPa. 5.9 Two balances, with the following characteristics: one is an analytical balance with an accuracy of 0,1 mg; the other is a balance with an accuracy of 0,1 g. 5.10 Device for making the “cigarette”, as shown in Figure 2. The procedure for making the “cigarette” is as shown in Figure 2 and comprises a mould
