本欧洲标准规定了在通过经认证的苯甲酸燃烧校准的炸弹量热仪中，以恒定体积和25℃的参考温度测定固体生物燃料的总热值的方法。 获得的结果是分析样品在恒定体积下的总热值，所有的燃烧产物的水都是液态水。在实践中，生物燃料在恒定（大气）压力下燃烧，并且水不会冷凝（用烟道气蒸气除去）或冷凝。在这两个条件下，所用燃烧的操作热是恒定压力下燃料的净热值。也可以使用恒定体积的净热值;给出了计算这两个值的公式。 标准和生物燃料实验的一般原则和程序在主要文本中提供，而有关使用特定类型的量热仪器的原则和程序在附录A至C中描述。附件D包含执行校准和燃料实验的清单，其使用指定类型的量热计。附录E给出了一些说明一些计算的例子

This European Standard specifies a method for the determination of the gross calorific value of a solid biofuel at constant volume and at the reference temperature 25 °C in a bomb calorimeter calibrated by combustion of certified benzoic acid. The result obtained is the gross calorific value of the analysis sample at constant volume with all the water of the combustion products as liquid water. In practice, biofuels are burned at constant (atmospheric) pressure and the water is either not condensed (removed as vapour with the flue gases) or condensed. Under both conditions, the operative heat of combustion to be used is the net calorific value of the fuel at constant pressure. The net calorific value at constant volume may also be used; formulae are given for calculating both values. General principles and procedures for the calibrations and the biofuel experiments are presented in the main text, whereas those pertaining to the use of a particular type of calorimetric instrument are described in Annexes A to C. Annex D contains checklists for performing calibration and fuel experiments using specified types of calorimeters. Annex E gives examples to illustrate some of the calculations
