Test Method C690-86 (1997) Standard Test Method for Particle Size Distribution of Alumina or Quartz by Electric Sensing Zone Technique
测试方法C690-86 (1997):应用电感应区技术对氧化铝或石英的粒度分布测定的标准方法
Copyright 2001 AMERICAN SOCIETY FOR TESTING AND MATERIALS, West
1. Scope
1.1 This test method, one of several found valuable for the measurement of particle size, covers the determination of the particle size distribution of alumina or quartz powders (0.6 to 56.0 µm) using electric sensing zone particle size analyzers. These instruments use an electric current path of small dimensions which is modulated by individual particle passage through an aperture, and produces individual pulses of amplitude proportional to the particle volume.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 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.

Test Method E1772-95 Standard Test Method for Particle Size Distribution of Chromatography Media by Electric Sensing Zone Technique
测试方法E1772-95；应用电感应区技术对层析介质的粒度分布测定的标准方法
Copyright 2001 AMERICAN SOCIETY FOR TESTING AND MATERIALS, West
1. Scope
1.1 This test method is valuable for the measurement of particle size and covers determination of the particle size distribution of chromatography media in the overall size range of approximately 1 to 450 µm using the electric sensing zone (ESZ) apparatus. This instrument uses an electric current path of small dimensions that is modulated by individual particle passage through an aperture and produces individual pulses of amplitude proportional to the particle volume (1).
1.2 The values stated in SI units are to be regarded as the standard.
1.3 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

Test Method F751-83 (1997) Standard Test Method for Measuring Particle Size of
测试方法F751-83 (1997)；测量具有宽广粒度范围干燥调色剂（色粉、墨粉）的标准方法
Copyright 2001 AMERICAN SOCIETY FOR TESTING AND MATERIALS, West
1. Scope
1.1 This test method covers a dual-aperture particle size analysis using an electronic sensing zone apparatus. Dry inks, toners, etc., are covered. Particles as small as 1.0-µm diameter and as large as 80µm diameter in a single powder system can be analyzed.
1.2 This test method is for particulate systems having a size range greater than 20 to 1, therefore requiring two apertures. For applications where particle size difference is between 1.4 µm and 80 µm and having a 20 to 1 or less size range, the simpler procedure found in Test Method F577 should be used.
1.3 This standard does not purport to address all of the safety problems, 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.

Test Method F577-83 (1997) Standard Test Method for Particle Size Measurement of Dry Toners
测试方法F577-83 (1997)；干燥调色剂（色粉、墨粉）粒度测量的标准方法
Copyright 2001 AMERICAN SOCIETY FOR TESTING AND MATERIALS, West
1. Scope
1.1 This test method covers a single aperture particle size analysis using an electronic sensing zone apparatus. Dry inks, toners, etc., are covered. Particles as small as 1.4 µm and as large as 80 µm can be analyzed.
1.2 This standard does not purport to address all of the safety problems, 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.

Test Method D4438-85 (1997) Standard Test Method for Particle Size Distribution of Catalytic Material by Electronic Counting
测试方法D4438-85 (1997):应用电感应计数法对催化媒的粒度分布测定的标准方法
Copyright 2001 AMERICAN SOCIETY FOR TESTING AND MATERIALS, West
1. Scope
1.1 This test method covers the determination of particle size distribution of catalyst and catalyst carrier particles using an electroconductive sensing method and is one of several valuable methods for the measurement of particle size.
1.2 The range of particle sizes investigated was 20 to 150 µm equivalent spherical diameter. The technique is capable of measuring particles above and below this range. The instrument used for this method is an electric current path of small dimensions that is modulated by individual particle passage through an aperture, and produces individual pulses of amplitude proportional to the particle volume.
1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Practice D3451-92 Standard Practices for Testing Polymeric Powders and Powder Coatings
D3451-92:测量多聚化粉末与粉末状涂料的粒度分布的标准方法
Copyright 2001 AMERICAN SOCIETY FOR TESTING AND MATERIALS, West
1. Scope
1.1 These practices cover the selection and use of procedures for testing polymeric powders and powder coatings. The test methods included are listed in Table 1. Where more than one test method is listed for the same characteristic, no attempt is made to indicate superiority of one method over another. Selection of the methods to be followed must be governed by experience and the requirements in each individual case, together with agreement between the purchaser and the seller.
1.2 These practices describe the testing of polymeric powders as applied by electrostatic spray, fluidized bed, or any other applicable method.
1.3 These practices apply to proper and safe packaging, shipping and receiving, and storage and handling during use and application of polymeric powders.
1.4 This standard does not purport to address all of the safety problems, 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.

Practice F660-83 (1993) Standard Practice for Comparing Particle Size in the Use of Alternative Types of Particle Counters
测试方法F660-83 (1993):对比可选择的两类别粒度计数器优劣的标准方法
Copyright 2001 AMERICAN SOCIETY FOR TESTING AND MATERIALS, West
1. Scope
1.1 This practice provides a procedure for comparing the sizes of nonspherical particles in a test sample determined with different types of automatic particle counters, which operate on different measuring principles. （本规则为使用不同原理、不同型号的自动粒子计数器对非球形样品颗粒测量提供一种判断优劣和比较的可靠方法。）
1.3 The practice considers rigid particles, free of fibers, of the kind used in studies of filtration, such as: commercially available test standards of quartz or alumina, or fly ash, or some powdered chemical reagent, such as iron oxide or calcium sulfate.
1.4 Three kinds of automatic particle counters are considered:（三种类型的自动粒子计数器）
1.5 This practice also considers the use of instruments that provide sedimentation analyses（本规则也适用于沉降法的分析仪）, which is to say provide measures of the particle mass distribution as a function of Stokes diameter. The practice provides a way to convert mass distribution into number distribution so that the meaning of Stokes diameter can be related to the diameter measured by the instruments in 1.4.
1.6 This standard does not purport to address all of the safety problems, 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.
