本标准规定了筛分法测定天然锰矿石或加工产品(例如球团矿、烧结矿和人造块矿)粒度分布的方法。
本 标准中“锰矿”或“矿石”是指上述种类的物质。
本标准中的方法同样适用一个或多个筛子测定粒度。
本标准的目的是为锰矿石的任一试验包括粒度测定提供基础,并为合同方买卖锰矿石时所用。
当本标准用于对比试验时,为避免纠纷,有关方应就具体使用的方法达成协议。

Scope

This standard specifies the method for determining the particle size distribution of natural manganese ores or processed products (such as pellets, sinters and artificial lumps) by sieving. "Manganese ore" or "ore" in this standard refers to the above-mentioned kinds of substances. The method in this standard also applies one or more sieves to determine particle size. The purpose of this standard is to provide a basis for any test of manganese ore, including particle size determination, and to be used by contracting parties when buying or selling manganese ore. When this standard is used for comparative tests, in order to avoid disputes, the parties concerned should reach an agreement on the specific method used.
