BS ISO 9599:2015规定了重量损失法，用于测定 铜、铅、锌和硫化镍精矿分析样品中的吸湿水分含量。本方法适用于不含挥发性有机物的铜、铅、锌和硫化镍精矿 浮选药剂，例如煤油，吸湿含水量在0.05%之间 （m/m）和2%（m/m）。吸湿性含水量用于校正分析结果 平衡的湿度水平达到干基。注:使用本国际标准测定吸湿含水量的结果应 不得作为浓缩物样品分析的一部分进行报告。无论何时 如果需要运输浓缩物，应使用ISO 10251。吸湿含水量的测定 体积含水量的测定是相互联系的。在两种测定中，结果相同 必须达到干燥状态，以确定批次的正确金属含量。本方法不适用于易氧化的硫化物精矿（见6.3，注2）。 附录A列出了一种改进的程序，可用于易受影响的硫化物浓缩物 氧化。交叉引用:ISO 10251ISO 12743购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS ISO 9599:2015 specifies a gravimetric loss-in-mass method for the determination of the hygroscopic moisture content in analysis samples of copper, lead, zinc, and nickel sulfide concentrates.The method is applicable to copper, lead, zinc, and nickel sulfide concentrates free from volatile organic flotation reagents, for example kerosene, and with hygroscopic moisture contents between 0,05 % (m/m) and 2 % (m/m). The hygroscopic moisture content is used to correct the analysis results from the equilibrated moisture level to the dry basis.NOTE The result of the determination of hygroscopic moisture content using this International Standard should not be reported as part of the analysis of a concentrate sample. Whenever the bulk moisture content of a commercial shipment of concentrate is required, ISO 10251 should be used. The determination of hygroscopic moisture content and the determination of bulk moisture content are connected with each other. In both determinations, the same state of dryness has to be achieved, in order to ascertain the correct metal content of a lot.This method is not applicable to sulfide concentrates that are susceptible to oxidation (see 6.3, note 2). Annex A sets out a modified procedure, which can be used for sulfide concentrates that are susceptible to oxidation.Cross References:ISO 10251ISO 12743All current amendments available at time of purchase are included with the purchase of this document.
