Designation:D364716Standard Practice forClassifying Reinforced Plastic Pultruded Shapes Accordingto Composition1This standard is issued under the fixed designation D3647;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()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice outlines a method for classifying rein-forced plastic pultruded shapes according to their composition.1.2 One objective of this practice is to provide a codificationmeans and descriptive limits for classification.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.NOTE1There is no known ISO equivalent to this standard.2.Terminology2.1 The definitions of reinforcement material,reinforcementtype,resin type,and filler amount and their respective levelsare described below.NOTE2As an example,a pultruded shape made from a polyester resinmix with 13%filler and glass roving reinforcement plus woven tape onthe surface comprising perhaps 4%of the total would be designated as“GRPF”.2.2 Reinforcement Materials:2.2.1 GFiberglass constitutes 90%or more by weight oftotal reinforcement.2.2.2 CCarbon fibers constitute 90%or more by weightof total reinforcement.2.2.3 OOther fibers constitute 90%of reinforcement.2.2.4 SSpecial composition not covered above.2.3 Reinforcement Type:2.3.1 RRoving constitutes 90%of total reinforcement.2.3.2 MContinuous Filament Mat(CFM)constitutes90%of total reinforcement.2.3.3 CCombinations of CFM,roving,stitched,or wovenreinforcements none of which constitutes 90%of the totalreinforcements.2.3.4 WWoven fabric constitutes 90%of total reinforce-ment.2.3.5 SStitched fabric constitutes 90%of total reinforce-ment.2.4 Resin Type:2.4.1 PPolyester.2.4.2 EEpoxy.2.4.3 VVinylester.2.4.4 FPhenolic2.4.5 UUrethane/Urethane Hybrid2.4.6 OOthers.2.5 Filler Amount:2.5.1 UFiller used is less than 5%of resin weight.2.5.2 FFiller used is 5%or more of the resin weight.3.Classification3.1 In classifying the reinforced plastic pultruded shapeaccording to composition,four separate aspects of the compo-sition will be considered.3.2 The composition will be identified by the use of fourcapital letters.The sequential position of each letter will haveparticular significance in describing the composition.Inaddition,the letter itself will have further specific descriptivevalue.3.3 The classification method will be based upon the four-letter code in which each position of this code will have thefollowing significance:3.3.1 Reinforcement MaterialThe first letter in the com-position code will identify the reinforcement material utilized.3.3.2 Reinforcement TypeThe second letter in the codewill describe the type of reinforcement material employed.3.3.3 Resin TypeThe third position in the code willdescribe the type of resin employed.3.3.4 Filler AmountThe fourth and last position in thecode will define relative amount of filler employed.1This practice is under the jurisdiction ofASTM Committee D20 on Plastics andis the direct responsibility of Subcommittee D20.18 on Reinforced ThermosettingPlastics.Current edition approved Sept.1,2016.Published September 2016.Originallyapproved in 1978.Last previous edition approved in 2009 as D3647-09.DOI:10.1520/D3647-16.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 SUMMARY OF CHANGESCommittee D20 has identified the location of selected changes to this standard since the last issue(D3647-09)that may impact the use of this standard.(September 1,2016)(1)Revised 2.3.2 and 2.3.3.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.Users of this standard are expressly advised that determination of the validity of any such patent rights,and the riskof infringement of such rights,are entirely their own responsibility.This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years andif not revised,either reapproved or withdrawn.Your comments are invited either for revision of this standard or for additional standardsand should be addressed to ASTM International Headquarters.Your comments will receive careful consideration at a meeting of theresponsible technical committee,which you may attend.If you feel that your comments have not received a fair hearing you shouldmake your views known to the ASTM Committee on Standards,at the address shown below.This standard is copyrighted by ASTM International,100 Barr Harbor Drive,P
