1.1 本规程给出了确定适当样本大小、大小类宽度、特征液滴大小和液滴大小分布的分散测量的程序。使用特定设备测量液滴的准确性和校正程序不属于本规程的一部分。注意采样类型（空间、通量敏感或两者均不），并注意所需的转换（未指定方法）。假设数据是按液滴大小计数的。假设液滴尺寸为等效体积球体的直径。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 该分析适用于所有液滴分布，但规定了具体限制的情况除外。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 这些标准 6. 程序为液滴数据的分析提供了统一的基础。

1.1 This practice gives procedures for determining appropriate sample size, size class widths, characteristic drop sizes, and dispersion measure of drop size distribution. The accuracy of and correction procedures for measurements of drops using particular equipment are not part of this practice. Attention is drawn to the types of sampling (spatial, flux-sensitive, or neither) with a note on conversion required (methods not specified). The data are assumed to be counts by drop size. The drop size is assumed to be the diameter of a sphere of equivalent volume. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 The analysis applies to all liquid drop distributions except where specific restrictions are stated. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 These criteria 6 and procedures provide a uniform base for analysis of liquid drop data.
