1、Designation: E 1617 97 (Reapproved 2007)Standard Practice forReporting Particle Size Characterization Data1This standard is issued under the fixed designation E 1617; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、 revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONCorrelation and comparison of particle size measurement data are of general importance toresearchers, processors, supplie
3、rs, vendors, and users of particulate materials. Since there arenumerous methods and devices in use, comparisons of size measurement data are subject to perceivedinconsistencies that may be much reduced by the use of standardized reporting.Data generated by any one size measurement method may be con
4、sistent in many respects, yet betroublesome to correlate due to variances in data processing and reporting formats among equipmentmanufacturers. Data generated from methods employing different physical principles present seriouscorrelation problems due to their sensing of different parameters relate
5、d to particle size and someunrelated, such as density, shape and optical properties. Standardized reporting may reduce confusionresulting from different particle size measurement practices.1. Scope1.1 This practice covers reporting particle size measurementdata.1.2 This practice applies to particle
6、size measurement meth-ods, devices, detail levels, and data formats for dry powders,and wet suspensions of solids, gels, or emulsion droplets. Thispractice does not pertain to liquid particles.NOTE 1For information on reporting liquid particle measurementdata, refer to Practice E 799.1.3 This practi
7、ce does not concern particle concentrationinformation.1.4 This practice uses SI (Systme International) units asstandard. State all numerical values in terms of SI units unlessspecific instrumentation software reports particle size informa-tion, including percentiles, indices, and distributions as ta
8、bu-lations and graphs using alternate units. In this case, presentboth 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 thesafety concerns, if any, associated with its use. It is the
9、responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Signifi
11、cance and Use3.1 When evaluating the particle size information, if theprocedures of the data processing are not available, the user ofthe data must make assumptions concerning the reported datain the event of analytical inconsistencies. In order for differentdata sets to be compared it is crucial th
12、at the parties report theanalytical techniques and methods or procedures for evaluat-ing, calculating, compiling or otherwise processing the data tobe reported.3.2 Particle size characterization information can be re-ported in three levels of detail in order to satisfy users needs.1This practice is
13、under the jurisdiction of ASTM Committee E29 on Particle andSpray Characterization and is the direct responsibility of Subcommittee E29.02 onNon-Sieving Methods.Current edition approved April 1, 2007. Published May 2007. Originallyapproved in 1994. Last previous edition approved in 2002 as E 1617 97

Level 1 information may be sufficient
16、 in such cases asidentifying a certain grade of a material or when detailedknowledge of analytical methodology is not needed.3.2.2 Level 2 presumes the need for knowledge of method-ology on the users part and allows the user to make a moreinformed judgment about the information provided in Level 1.3
17、.2.3 Level 3 provides detailed written procedures to allowduplication of the measurement.3.2.4 Information provided through Levels 2 and 3 willallow users to perform comparative material evaluations be-tween several suppliers, set specifications or define a purchaseagreement, perform inter-laborator
18、y studies and most impor-tantly resolve disputes between supplier and users.3.3 Reported particle size measurement is a function of boththe actual particle dimension and shape factor as well as theparticular physical or chemical properties of the particle beingmeasured. Caution is required when comp
19、aring data frominstruments operating on different physical or chemical param-eters or with different particle size measurement ranges.Sample acquisition, handling and preparation can also affectthe reported particle size results.4. Procedure4.1 The particle size characterization report shall include
20、Level 1 information with Level 2 or 3, or both, being suppliedupon agreement between supplier and user. Level 2 reportsshall include all information provided in Level 1. Level 3reports shall include all information provided in Levels 1 and2.4.2 The supplier of a product lot shall provide the user wi
21、that least Level 1 information in a mutually agreed upon timeframe relative to delivery of the product. Structure the reportusing 5.2 through 5.2.8 as guidelines.4.3 Levels 2 and 3 shall be made available to the user atmutually agreeable costs and terms of disclosure. Structure thereports using 5.3
22、through 5.3.14.3 and 5.4 through 5.4.18,respectively, as guidelines.4.4 Particle Size Characterization Data SheetLevel 1:4.4.1 The Level 1 report shall contain the designation of thisASTM standard practice (E 1617).4.4.2 The report shall contain sample identification infor-mation such as material ty
