1、Designation:D683508(Reapproved 2014)Standard Classification System forThermoplastic Elastomer-Ether-Ester Molding and ExtrusionMaterials(TEEE)1This standard is issued under the fixed designation D6835;the number immediately following the designation indicates the year oforiginal adoption or,in the c
2、ase of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This classification system covers segmented blockcopolyether-ester elastomers suitable for mold
3、ing and extru-sion.1.2 This classification system allows for the use of seg-mented block copolyether-ester elastomers that are recycledprovided that the requirements as stated in this classificationsystem are met.The proportions of recycled material used,aswell as the nature and amount of any contam
4、inant,however,cannot be covered practically in this specification.1.3 The properties included in this classification system arethose required to identify the compositions covered.It ispossible that there are other requirements necessary to identifyparticular characteristics important to specialized
5、applications.One way of specifying them is by using the suffixes as given inSection 5.1.4 This classification system and subsequent line callout(specification)are intended to provide a means of calling outplastic materials used in the fabrication of end items or parts.It is not intended for the sele
6、ction of materials.Materialselection is best made by those having expertise in the plasticfield after careful consideration of the design and the perfor-mance required of the part,the environment to which it will beexposed,the fabrication process to be employed,the costsinvolved,and the inherent pro
