A range of industrial minerals was tested using the rotating drum and the continuous drop methods, the two methods proposed by the published European standard EN 15051 [CEN. (2006) EN 15051 Workplace atmospheres-measurement of the dustiness of bulk materials-requirements and test methods. Brussels, Belgium: European Committee for Standardization], to evaluate and compare their dustiness. The assessment of bulk materials dustiness can help to develop less dusty products and to reduce dust exposure to the workers by improving the processing of minerals. The European standard EN 15051 (CEN, 2006) proposes a classification system that was developed with the intention to assist in the labelling of products in the future. This paper presents a comparison of both test methods in classifying industrial minerals. The correlation between the dustiness measured by the two methods for the inhalable and respirable fractions is given. The results show there is no unambiguous dependence of the dustiness on the grain size of an industrial mineral. Although dustiness can significantly be affected by product moisture, the influence of this parameter is not studied in detail as the industrial minerals were tested in the conditions they are sold, as the standard requires. Especially, the classification of substances with respect to different classes of dustiness was found to be problematic, as the two methods are by no means yielding identical classification groups for all the substances. In any use of the standard (EN 15051; CEN, 2006) for labelling purposes, a revision of the present classification system provided in the standard is required for industrial minerals.
使用转鼓法和连续滴加法对一系列工业矿物进行了测试，这两种方法是已发布的欧洲标准EN 15051[欧洲标准化委员会（CEN）。（2006年）EN 15051工作场所大气——散装材料粉尘iness的测量——要求和测试方法。比利时布鲁塞尔：欧洲标准化委员会]中提出的，以评估和比较它们的粉尘iness。对散装材料粉尘iness的评估有助于开发粉尘较少的产品，并通过改进矿物加工减少工人接触粉尘的机会。欧洲标准EN 15051（CEN，2006年）提出了一种分类系统，其目的是为未来产品标签提供帮助。本文介绍了两种测试方法在工业矿物分类中的比较。给出了两种方法测量的可吸入和可呼吸部分粉尘iness之间的相关性。结果表明，工业矿物的粉尘iness与粒度之间没有明确的依赖关系。虽然产品湿度会显著影响粉尘iness，但由于按照标准要求在工业矿物销售时的条件下对其进行了测试，因此未详细研究该参数的影响。特别是，发现物质在不同粉尘iness等级方面的分类存在问题，因为这两种方法对于所有物质绝不可能产生相同的分类组。在将标准（EN 15051；CEN，2006年）用于标签目的的任何情况下，工业矿物都需要对标准中目前提供的分类系统进行修订。
