BS ISO 12800:2017给出了测定成品比表面积的指南 二氧化铀粉末中氮含量的容量法或重量法测定 吸附在粉末上，并可应用于其他类似材料，例如U3O8、UO2-PuO2粉末， 以及其他具有类似表面积的物体，例如粉末颗粒或绿色颗粒，前提是 满足所述条件。包括使用其他吸附气体的修改。只要预期值在1 m2/g和10 m2/g之间，该方法就具有相关性。交叉引用:BS ISO 9277:2010ISO 9277:2010 Ed 2购买本文件时，包括所有当前可用的修改件。

BS ISO 12800:2017 gives guidelines on the determination of the specific surface area of as-fabricated uranium dioxide powder by volumetric or gravimetric determination of the amount of nitrogen adsorbed on the powder, and can be applied to other similar materials, e.g. U3O8, UO2-PuO2 powders, and other bodies with similar surface areas, e.g. powder granules or green pellets, provided that the conditions described are fulfilled. Modifications using other adsorbing gases are included.The method is relevant as long as the expected value is in the range between 1 m2/g and 10 m2/g.Cross References:BS ISO 9277:2010ISO 9277:2010 Ed 2All current amendments available at time of purchase are included with the purchase of this document.
