Four methods for evaluating the dustiness of powders have been compared. The relatively new UNC Dustiness Tester first described by Boundy et al. (2006) in the Annals of Occupational Hygiene, which was developed specifically for the measurement of hazardous and/or highly potent substances, a single-drop device, a rotating-drum method, and a continuous drop-down apparatus. The four methods show four different ratings of dustiness for nine reference materials. This article describes the differences, explores reasons for the deviations, identifies a need for distinct dustiness test methods, and highlights the significance for occupational health and safety.
已对四种评估粉末扬尘性的方法进行了比较。相对较新的UNC扬尘测试仪最早由邦迪等人于2006年在《职业卫生学年鉴》中描述，该测试仪是专门为测量危险和/或高效能物质而开发的，此外还有单滴装置、转鼓法和连续下拉装置。这四种方法对九种参考材料显示出四种不同的扬尘等级。本文描述了这些差异，探讨了偏差原因，确定了对不同扬尘测试方法的需求，并强调了其对职业健康与安全的重要性。
