calorific
 ISO 6976:1995, Natural gas -- Calculation of calorific values, density, relative density and Wobbe index from composition $166.00 Specifies methods for the calculation of the superior calorific value and the inferior calorific value, density, relative density and Wobbe index of dry natural gas and other combustible gaseous fuels, when the composition of the gas by mole fraction is known. Replaces the first edition, which has been technically revised.  ISO 1928:1995, Solid mineral fuels - Determination of gross calorific value by the bomb calorimetric method, and calculation of net calorific value $157.00 Specifies a method for the determination of the gross calorific value of a solid mineral fuel in a bomb calorimeter. Gives formulae for calculating the net calorific value at constant pressure and volume. Presents general principles and procedures for the calibrations. Cancels and replaces the first edition, which has been technically revised.  ISO 9831:1998, Animal feeding stuffs, animal products, and faeces or urine - Determination of gross calorific value - Bomb calorimeter method $116.00 This International Standard specifies a method for the determination of the gross calorific value of animal feeding stuffs, animal products and faeces or urine at constant volume in an adiabatic, an isothermal, or a static bomb calorimeter.The result obtained by this method is the gross calorific value of the test sample at constant volume, the water of the combustion products being condensed to liquid at the calorimeter temperature. |
