标准摘要
[中文适用范围]： 该文件规定了一种测定焦炭样品粒度分布的方法，该焦炭样品具有通常通过延迟石油焦的煅烧产生的典型粒度分布。 同样的程序适用于煅烧无烟煤的托运。 本文件不适用于通过筛分和粉碎制备的碳材料级分或过滤细粉。 该方法适用于测定 0.25 mm 至 16 mm 范围内的颗粒尺寸，因为高于和低于该范围的粒度分布百分比之和通常小于 10%。 本文件不适用于使用特定粉尘测试来确定低于 0.25 毫米的颗粒尺寸。 [外文原描述]： ISO 12984:2018 specifies a method for the determination of the particle size distribution of a sample of coke having a typical size distribution as normally produced by calcination of delayed petroleum coke. The same procedure is applicable to consignments of calcined anthracite. This document does not apply to fractions of carbon material prepared by sieving and crushing or to filter fines. This method is applicable to the determination of particle sizes ranging from 0,25 mm to 16 mm, as the sum of the percentages of the size distribution above and below this range is typically less than 10 %. This document does not apply to determining particle sizes below 0,25 mm where a specific test for dust is used.
