1、Designation: D3647 16Standard 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 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.1. Scope*1.1 This practice outlines a method for classifying rein-forced plastic pultruded shapes according to their composition

3、.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 saf

4、ety and health practices and determine the applica-bility of regulatory limitations prior to use.NOTE 1There 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 descri

Classification3.1 In classifying the reinfor

9、ced 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. Inadditio

10、n, 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 reinf
