1、Designation: D 6436 02Standard Guide forReporting Properties for Plastics and ThermoplasticElastomers1This standard is issued under the fixed designation D 6436; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revi

2、sion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope *1.1 This guide provides recommendations for reporting theresults of property values for plastics and thermoplastic elas-tomers i

3、n published literature, data sheets, presentations, com-parative analysis, and so forth. It is intended to minimizeconfusion when comparing the data from several sources.1.2 This standard is not intended to replace recommenda-tions within the test methods for reporting data. Refer to thetest method

4、or use other guidance to determine the number ofsignificant figures for reporting laboratory test results.NOTE 1There is no similar or equivalent ISO standard.2.

Significance and Use4.1 This guide is intended to provide ready access to therecommended property name, test method reference, maximumnumber

7、of significant digits,5and appropriate units for com-monly used plastics and thermoplastic elastomer tests.4.2 It is particularly useful for those involved in the writingand proofreading of documents containing data for a largenumber of tests since the need to go to each individual testmethod should

8、 be greatly minimized.4.3 SI units are to be regarded as the standard. U.S.Customary units and conversion factors are provided to accom-modate those situations where it is necessary to report both.U.S. Customary refers to units commonly used in the UnitedStates and is not always the same as inch-pou
