1、Designation: D5205 10Standard Classification System and Basis for Specification forPolyetherimide (PEI) Materials1This standard is issued under the fixed designation D5205; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year o
2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This classification system covers
3、unfilled, filled, andreinforced polyetherimide materials suitable for injectionmolding and extrusion.1.2 This classification system is not intended for the selec-tion of materials, but only as a means to call out plasticmaterials to be used for the manufacture of parts. The selectionof these materia
4、ls is to be made by personnel with expertise inthe plastics field where the environment, inherent properties ofthe materials, performance of the parts, part design, manufac-turing process, and economics are considered.1.3 The properties included in this classification system arethose required to ide
5、ntify the compositions covered. Otherrequirements necessary to identify particular characteristicsimportant to specialized applications are to be specified byusing the suffixes as given in Section 5.1.4 The values stated in SI units are to be regarded asstandard.1.5 The following precautionary cavea

17、 Devices and Appliances3. Terminology3.1 DefinitionsThe terminology used in this classificationsystem is in accordance with Terminologies D883 and D1600.3.2 Abbreviations:AbbreviationThe polyetherimide mate-rials will be designated “PEI” as specified in TerminologyD1600.4. Classification4.1 Unfilled
18、 polyetherimide materials are classified intogroups according to their composition. These groups aresubdivided into classes and grades as shown in Table PEI.NOTE 2An example of this classification system is given as follows.The designation ASTM D5205 PEI 0114 indicates the following:PEI = polyetheri
19、mide as found in Terminology D1600,01 = polyetherimide (group),1 = general purpose (class), and4 = requirements given in Table PEI (grade).4.1.1 To facilitate incorporation of future or special materi-als the “other” category (0) for group, class, and grade is shownin Table PEI. The basic properties
20、 of these materials can beobtained from Tables A or B as they apply.4.2 Reinforced, pigmented, filled, and lubricated versions ofpolyetherimide materials are classified in accordance withTables PEI and A or B. Table PEI is used to specify theunreinforced material and Table A or B is used to specify
21、theproperty requirements after the addition of reinforcements,pigments, fillers, or lubricants at the nominal level indicated(see 4.2.1).4.2.1 A single letter shall be used to indicate the majorcategory of the reinforcement, along with two numbers thatindicate the percentage of additive(s) by mass,
22、with thetolerances as tabulated as follows:Category Material Tolerance(Based on the Total Mass)C Carbon and graphite fiber-reinforced62 percentage pointsG Glass-reinforced15 % glass content 63 percentage pointsL Lubricants (such as PTFE,graphite, silicone, andmolybdenum disulfide)Depends upon materi
23、al andprocessto be specifiedM Mineral-reinforced 62 percentage pointsR Reinforced-combination/mixtures of reinforcements orother fillers/reinforcements63 percentage points based onthe total reinforcementNOTE 3If necessary, additional requirements are specified usingsuffixes as described in Section 5
24、. Special agreements on tolerances arerequired when levels are below 5 %. Ash content of filled or reinforcedmaterials may be determined using Test Method D5630 where applicable.4.2.2 Specific requirements for reinforced, filled, or lubri-cated polyetherimide materials shall be shown by a six-charac
25、ter designation. The designation will consist of the letter“A” or “B” and the five digits comprising the cell numbers forthe property requirements in the order as they appear in TablesAorB.4.2.2.1 Although the values listed are necessary to includethe range of properties available in existing materi
26、als, this doesnot imply that every possible combination of the propertiesexists or can be obtained.4.2.3 When the grade of the basic materials is not shown, oris not important, the use of “O”-grade classification shall beused for reinforced materials in this system.NOTE 4An example of this classific
27、ation for a polyetherimide mate-rial is given as follows. The designation ASTM D5205PEI0110G10A48266 would indicate the following material requirements:PEI 0110 = general-purpose polyetherimide from Table PEI,G10 = glass reinforced at nominal 10 % level,A = Table A property requirements,4 = 110-MPa
28、tensile strength, min,8 = 13790-MPa flexural modulus, min,2 = 4 g/10 min; melt flow, min,6 = 205-MPa flexural strength, min, and6 = 230C deflection temperature, min.If no properties are specified, the designation would beASTM D5205 PEI0110G10A00000.5. Suffixes5.1 When requirements not covered by the
29、 basic cell tablesneed to be specified, suffixes shall be used. The followingsuffixes shall be used when appropriate. Additional suffixes arefound in Classification System D4000 when needed.5.1.1 E = Electrical requirements as designated by thefollowing digits:First Digit0 = specimen to be specified
