1、Designation: D6835 08 (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
2、 the case 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 suita
3、ble for molding 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
4、 of any contaminant, 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
5、 to specialized 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 inte
6、nded for the selection 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
7、, and the inherent properties of the material other thanthose covered by this classification system.1.5 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.6 The following precautionary caveat pertains only to thetest methods port
8、ion, Section 11, of this classification system.This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatoryl
9、imitations prior to use.NOTE 1This standard, ISO 14910-1, and ISO 14910-2 address thesame subject matter, but differ in technical content.2.

Terminology3.1 DefinitionsThe terminology used in this classificationsystem is in accordance with Terminologies D883 and D1600.4. Classification4.1 Polyether-ester elastomers are classified into groups inaccordance with
19、flexural modulus. These groups are subdi-vided into classes by viscosity range (flow rate) and are furthersubdivided into grades by tensile properties, as shown in thebasic property table (Table TEEE).NOTE 2AN EXAMPLE OF THIS CLASSIFICATION SYSTEM IS GIVEN AS FOLLOWS:THE DESIGNATION TEEE0311 INDICAT
20、ES THE FOLLOWING:TEEE = polyether-ester elastomer03 (group) = flexural modulus from 125 to 325 MPa1 (class) = flow rate from 2 to 12 g/10 min1 (grade) = property requirements as given in Table TEEE4.1.1 To facilitate the incorporation of future or specialmaterials, the other category for group (00),
21、 class (0), andgrade (0) is shown in Table TEEE.4.2 Reinforced, filled, and/or lubricated versions of thepolyether-ester materials that are not in Table TEEE areclassified in accordance with Tables TEEE and A. Table TEEEis used to specify the group of polyester materials and Table Ais used to specif
22、y the property requirements after the additionof reinforcements or lubricants at the nominal level indicated(see 4.2.1).4.2.1 Reinforced, filled, and/or lubricated versions of thebasic materials are identified by a single letter that indicates thereinforcement or filler used and two digits that indi
23、cate thenominal quantity in percent by weight. Thus, a letter designa-tion G for glass-reinforced and 33 for % of reinforcement, G33,specifies a filled material with a nominal glass level of 33 %.The reinforcement letter designations and associated tolerancelevels are shown in the following table:Sy
24、mbol Material ToleranceC carbon and graphite fiber 2 %G glass 2 %L lubricants (for example, PTFE,graphite, silicone, andmolybdenum disulfide)depends upon material andprocessto be specifiedM mineral 2 %R combination of reinforcementsor fillers, or both3 %NOTE 3This part of the classification system u
25、ses the percent ofreinforcements or additives, or both, in the control of the modified basicmaterial. The types and percentages of reinforcements and additives aresometimes shown on the suppliers technical data sheet unless they areproprietary in nature. If necessary, additional callout of these rei
26、nforce-ments and additives can be accomplished by the use of the suffix part ofthe system (see Section 5).4.2.2 Specific requirements for reinforced, filled, or lubri-cated polyether-ester materials shall be shown by a six-character designation. The designation will consist of the letter“A” and the
27、five digits comprising the cell numbers for theproperty requirements in the order as they appear in Table A.4.2.2.1 Although the values listed are necessary to includethe range of properties available in existing materials, usersshall not infer that every possible combination of the propertiesexists
28、 or can be obtained.4.2.3 When the grade of the basic material is not known oris not important, the use of “0” grade classification will be usedfor reinforced materials in this system.NOTE 4An example of a reinforced polyether-ester elastomer of thisclassification system is as follows. The designati
29、on TEEE0310G-20A45630 would indicate the following material requirements from TableA:TEEE0310 = polyether-ester elastomer from Table TEEEG20 = glass reinforced at 20 % nominal (see 4.2.1)A = Table A property requirements4 = flexural modulus of 150 MPa, min5 = flexural modulus of 450 MPa, max6 = tens

Suff
35、ixes5.1 When additional requirements are needed that are notcovered by the basic requirements or cell-table requirements,they shall be indicated through the use of suffixes.5.2 A list of suffixes can be found in Classification D4000(Table 3) and can be used to indicate additional requirements asappr
36、opriate. Additional suffixes will be added to that classifi-cation system as test methods and requirements are developedand requested.6. General Requirements6.1 Basic requirements from the property or cell tables arealways in effect unless superseded by specific suffixrequirements, which always take
37、 precedence.6.2 The plastics composition shall be uniform and shallconform to the requirements specified herein.7. Detail Requirements7.1 The materials shall conform to the requirements inTables TEEE and A, and suffix requirements as they apply.7.2 For the purpose of determining conformance, all spe
38、ci-fied limits for a specification (line callout) based on thisclassification system are absolute limits, as defined in PracticeE29.7.3 With the absolute method, an observed value or acalculated value is not rounded off, but is to be compareddirectly to the specified limiting value. Conformance or n
39、on-conformance is based on this comparison.8. Sampling8.1 Sampling shall be statistically adequate to satisfy therequirements of 12.4.8.2 A batch or lot shall be constituted as a unit of manufac-ture as prepared for shipment and can consist of a blend of twoor more “production runs.”9.
