Industrial wire screens - Technical requirements and testings

ASTM E1617-97(2007) 报告粒度特性数据的标准规程

When evaluating the particle size information, if the procedures of the data processing are not available, the user of the data must make assumptions concerning the reported data in the event of analytical inconsistencies. In order for different data sets to be compared it is crucial that the parties report the analytical techniques and methods or procedures for evaluating, calculating, compiling or otherwise processing the data to be reported. Particle size characterization information can be reported in three levels of detail in order to satisfy userrsquo;needs. 3.2.1 Level 1 applies when only basic information about the material is required, and shall be provided with each shipment. This level represents the minimum information that shall be reported. Level 1 information may be sufficient in such cases as identifying a certain grade of a material or when detailed knowledge of analytical methodology is not needed. 3.2.2 Level 2 presumes the need for knowledge of methodology on the userrsquo;part and allows the user to make a more informed judgment about the information provided in Level 1. 3.2.3 Level 3 provides detailed written procedures to allow duplication of the measurement. 3.2.4 Information provided through Levels 2 and 3 will allow users to perform comparative material evaluations between several suppliers, set specifications or define a purchase agreement, perform inter-laboratory studies and most importantly resolve disputes between supplier and users. Reported particle size measurement is a function of both the actual particle dimension and shape factor as well as the particular physical or chemical properties of the particle being measured. Caution is required when comparing data from instruments operating on different physical or chemical parameters or with different particle size measurement ranges. Sample acquisition, handling and preparation can also affect the reported particle size results.1.1 This practice covers reporting 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 18212;For information on reporting liquid particle measurement data, refer to Practice E 799.1.3 This practice does not concern particle concentration information.1.4 This practice uses SI (Systme 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 E 380 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.

ASTM E161-96 精密电铸筛的标准规范

1.1 This specification covers the requirements for design and construction of electroformed sieves. These sieves are used to perform particle-size distribution analysis and in preparing narrowly designated particle-size fractions. They may also be used as reference standards when suitably calibrated. A method of calibrating these sieves is included in the Annex. Note 1--Complete instructions and procedures on the use and calibration of testing sieves are contained in ASTM Manual 32. This publication also contains a list of all published ASTM Standards on sieve analysis procedures for specific materials or industries.1.2 The sieve analysis results from two testing sieves of the same sieve designation may not be the same because of the variances in sieve opening permitted by this specification. To minimize the differences in sieve analysis results, the use of testing sieves matched on a performance basis is suggested. Note 2--For other types of sieves, see Specifications E11 and E323.1.3 The values stated in SI units shall be considered standard for the dimensions of the electroformed mesh openings and the size of the wires in the electroformed mesh. The values stated in inch units shall be considered standard with regard to the sieve frames.

ASTM E112-96(2004)e2 测定平均粒度的标准试验方法

1.1 These test methods cover the measurement of average grain size and include the comparison procedure, the planimetric (or Jeffries) procedure, and the intercept procedures. These test methods may also be applied to nonmetallic materials with structures having appearances similar to those of the metallic structures shown in the comparison charts. These test methods apply chiefly to single phase grain structures but they can be applied to determine the average size of a particular type of grain structure in a multiphase or multiconstituent specimen.1.2 These test methods are used to determine the average grain size of specimens with a unimodal distribution of grain areas, diameters, or intercept lengths. These distributions are approximately log normal. These test methods do not cover methods to characterize the nature of these distributions. Characterization of grain size in specimens with duplex grain size distributions is described in Test Methods E 1181. Measurement of individual, very coarse grains in a fine grained matrix is described in Test Methods E 930.1.3 These test methods deal only with determination of planar grain size, that is, characterization of the two-dimensional grain sections revealed by the sectioning plane. Determination of spatial grain size, that is, measurement of the size of the three-dimensional grains in the specimen volume, is beyond the scope of these test methods.1.4 These test methods describe techniques performed manually using either a standard series of graded chart images for the comparison method or simple templates for the manual counting methods. Utilization of semi-automatic digitizing tablets or automatic image analyzers to measure grain size is described in Test Methods E 1382.1.5 These test methods deal only with the recommended test methods and nothing in them should be construed as defining or establishing limits of acceptability or fitness of purpose of the materials tested.1.6 The measured values are stated in SI units, which are regarded as standard. Equivalent inch-pound values, when listed, are in parentheses and may be approximate.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.1.7 The paragraphs appear in the following order:
