Designation:D 5593 99e1Standard Classification forThermoplastic ElastomersOlefinic(TEO)1This standard is issued under the fixed designation D 5593;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.e1NOTEEditorially corrected the description for Group 02,Class 1 in Table TEO in April 2002.INTRODUCTIONThis classification is intended to be a system for calling out olefinic thermoplastic elastomers usedin the fabrication of end items or parts.It is not intended for the selection of materials.Materialselection should be made by those having expertise in the plastics field after careful consideration ofthe design and the performance required of the part,the environment to which it will be exposed,thefabrication processes to be employed,and the inherent properties of the material other than thosecovered by this classification.1.Scope*1.1 This classification covers olefinic thermoplastic elas-tomers(TEOs)made directly in a reactor or through acompounding process and suitable for injection molding,extrusion,blow molding,or other melt processing.Compound-ing ingredients may be present as necessary for the applicationsand may consist of reinforcements,fillers,stabilizers,colo-rants,and other ingredients.1.2 This classification allows for the use of those TEOmaterials,which can be recycled,reground,and reprocessed,provided that the requirements as stated in this classificationare met.The proportions of recycled material used,as well asthe nature and the amount of any contaminant,however,cannotbe practically covered in this classification.1.3 The properties included in this classification are thoserequired to identify the compositions for most applications.Other requirements may be necessary to further identifyparticular characteristics.These may be specified by using thesuffixes in accordance with Section 5.1.4 The values stated in SI units are to be regarded as thestandard.The inch-pound units are for information only.1.5 The following precautionary caveat pertains only to thetest method portion,Section 11,of this classification:Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.NOTE1There is no similar or equivalent ISO standard.2.Referenced Documents2.1 ASTM Standards:D 256 Test Methods for Impact Resistance of Plastics andElectrical Insulating Materials2D 412 Test Methods for Vulcanized Rubber and Thermo-plastic Rubbers and Thermoplastic ElastomersTension3D 618 Practice for Conditioning Plastics and ElectricalInsulating Materials for Testing2D 624 Test Method for Tear Strength of ConventionalVulcanized Rubber and Thermoplastic Elastomer3D 638 Test Method for Tensile Properties of Plastics2D 648 Test Method for Deflection Temperature of PlasticsUnder Flexural Load2D 696 Test Method for Coefficient of Linear Thermal Ex-pansion of Plastics2D 746 Test Method for Brittleness Temperature of Plasticsand Elastomers by Impact2D 790 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastics and Electrical Insulating Materi-als2D 792 Test Methods for Density and Specific Gravity(Rela-tive Density)and Density of Plastics by Displacement2D 883 Terminology Relating to Plastics2D 1238 Test Method for Flow Rates of Thermoplastics byExtrusion Plastometer2D 1435 Practice for Outdoor Weathering of Plastics2D 1566 Terminology Relating to Rubber3D 1600 Terminology Relating to Abbreviated Terms Relat-ing to Plastics21This classification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.15 on ThermoplasticMaterials.Current edition approved Nov.10,1999.Published February 2000.Originallypublished as D 5593 94.Last previous edition D 5593 94.2Annual Book of ASTM Standards,Vol 08.01.3Annual Book of ASTM Standards,Vol 09.01.1*A Summary of Changes section appears at the end of this standard.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.D 1898 Practice for Sampling Plastics4D 2240 Test Method for Rubber PropertyDurometerHardness3D 3418 Test Method for Transition Temperatures of Poly-mers by Thermal Analysis5D 3641 Practice for Injection Molding Test Specimens ofThermoplastic Molding and Extrusion Materials5D 3763 Test Method for High-Speed Puncture Properties ofPlastic Using Load and Displacement Sensors5D 3892 Practice for Packaging/Packing of Plastics5D 4000 Classification System for Specifying Plastic Mate-rials5D 5033 Guide for the Development of Standards Relating toProper Use of Recycled Plastics5E 29 Practice for Using Significant Digits
