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
