标准范围

指定工业煅烧产品的两种方法。第一种方法是使用四氯化碳蒸汽，如果材料密度超过3.75 g/ml；如果材料密度低于3.75 g/ml，则第二种方法（使用水蒸气）适用。通过将之前干燥的样品暴露在常规温度下四氯化碳或水蒸气饱和的大气中来评估吸附能力。在常规时间后测量相应蒸汽的吸附量。也得到了IUPAC的批准。

Specifies two methods for industrial calcined products. The first, using carbon tetrachloride vapour, is applicable if the density of the material exceeds 3.75 g/ml; the second, using water vapour, is applicable if the density of the material is lower than 3.75 g/ml. The adsorptive power is evaluated by exposure of a previously dried sample to an atmosphere saturated with carbon tetrachloride or water vapour at a conventional temperature. Measurement of the quantity of the corresponding vapour adsorbed after a conventional time. Has also been approved by the IUPAC.
