ASTM E799-03(2020)e1 液滴尺寸分析用测定数据标准和处理的标准实施规程

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.

BS ISO 21910-1:2020 精细气泡技术 微气泡的表征-尺寸指数的离线评估

What is ISO 219101 about?   ISO 21910 discusses the Characterization of microbubbles for Fine bubble technology. ISO 21910-1 outlines the evaluation method for the size index of microbubbles in microbubble dispersion. It is only applicable to microbubbles with or without shells in water within the range from 1 μm to 100 μm. ISO 21910-1 describes the sampling methods from the point generating or dispersing microbubbles in the retention container to the detecting point of the measuring instruments.   Who is ISO 21910-1 for?
