Designation:D 4617 03Standard Classification System forPhenolic Compounds(PF)1This standard is issued under the fixed designation D 4617;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.1.Scope*1.1 This classification system covers phenolic compoundssuitable for compression,transfer,or injection molding,or acombination thereof.1.2 This classification system is intended to be a means ofcalling out plastic materials used in the fabrication of end itemsor parts.It is not intended for the selection of materials.Material selection should be made by those having expertise inthe plastics field after careful consideration of the design andthe performance required of the part,the environment to whichit will be exposed,the fabrication process to be employed,theinherent properties of the material other than those covered bythis classification system,and the economics.1.3 The properties included in this classification system arethose required to identify the compositions covered.There maybe other requirements necessary to identify particular charac-teristics important to specialized applications.These will beagreed upon between the user and the supplier,by using thesuffixes specified in Section 5.1.4 The values stated in SI units are to be regarded as thestandard.1.5 The following precautionary caveat pertains only to thetest method portion,Section 13 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 regulatorylimitations prior to use.NOTE1ISO 800-1992(E)is similar but not equivalent to this classi-fication system.Product classification and characterization are not thesame.2.Referenced Documents2.1 ASTM Standards:D 256 Test Methods for Impact Resistance of Plastics andElectrical Insulating Materials2D 570 Test Method for Water Absorption of Plastics2D 618 Practice for Conditioning Plastics for Testing2D 638 Test Method for Tensile Properties of Plastics2D 648 Test Method for Deflection Temperature of PlasticsUnder Flexural Load2D 695 Test Method for Compressive Properties of RigidPlastics2D 790 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastics and Electrical Insulating Materi-als2D 792 Test Methods for Specific Gravity(Relative Density)and Density of Plastics by Displacement2D 796 Practice for Compression Molding Test Specimens ofPhenolic Molding Compounds2D 883 Terminology Relating to Plastics2D 1600 Terminology for Abbreviated Terms Relating toPlastics2D 1896 Practice for Transfer Molding Specimens of Ther-mosetting Compounds2D 3419 Practice for In-Line Screw-Injection Molding ofTest Specimens from Thermosetting Compounds3D 3892 Practice for Packaging/Packing of Plastics3D 4000 Classification System for Specifying Plastic Mate-rials3E 29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specification42.2ISO Standard:5ISO 8000-1992(E)3.Terminology3.1 DefinitionsFor definitions of technical terms pertain-ing to plastics used in this classification system see Terminolo-gies D 883,or D 1600,or both.4.Classification4.1 Phenolic compounds are classified into groups accord-ing to their application.These groups are subdivided intoclasses and grades as shown in Table PF.NOTE2An example of this classification system is as follows:The designation PF 111 indicates:1This classification system is under the jurisdiction ofASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.16 on ThermosettingMaterials.Current edition approved March 10,2003.Published April 2003.Originallyapproved in 1986.Last previous edition approved in 1996 as D 4617 96.2Annual Book of ASTM Standards,Vol 08.01.3Annual Book of ASTM Standards,Vol 08.02.4Annual Book of ASTM Standards,Vol 14.02.5Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036.1*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.PF=Phenol-Formaldehyde(Phenolic)as found in Terminology D 16001=General Purpose(Group)1=Cellulose Filled,Type III(Class)1=Compression Molding Grade with Requirements given in Table PF.(Grade)4.1.1 To facilitate the incorporation of future or specialmaterials,the“other unspecified”category(0)for group,class,and grade is shown in Table PF.The basic properties can beobtained from Table A.4.2 Specific requirements for special or new phenolic com-pounds shall be shown by a six-character designation.Thedesignation will consist of the letter A and the five digitscomprisin
