1.1本规程涵盖了粒度测量数据的报告。 1.2本规程适用于固体、凝胶或乳化液滴的干粉和湿悬浮液的粒度测量方法、装置、详细程度和数据格式。这种做法不适用于液体颗粒。 注1-有关报告液体颗粒测量数据的信息，请参阅规程E799。 1.3本规程不涉及颗粒浓度信息。 1.4本规程使用SI（Systeme International）单位作为标准。以国际单位制表示所有数值，除非特定仪器软件使用替代单位以表格和图形的形式报告粒径信息，包括百分位、指数和分布。 在这种情况下，在最终书面报告中提供报告的和等效的国际单位制。有关国际单位制的正确使用，请参阅规程E380。 1.5本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This practice covers the reporting of particle size measurement data. 1.2 This practice applies to particle size measurement methods, devices, detail levels, and data formats for dry powders, and wet suspensions of solids, gels, or emulsion droplets. This practice does not pertain to liquid particles. Note 1-For information on reporting liquid particle measurement data, refer to Practice E799. 1.3 This practice does not concern particle concentration information. 1.4 This practice uses SI (Systeme International) units as standard. State all numerical values in terms of SI units unless specific instrumentation software reports particle size information, including percentiles, indices, and distributions as tabulations and graphs using alternate units. In this case, present both reported and equivalent SI units in the final written report. Refer to Practice E380 for proper usage of SI units. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
