1、Designation: D 1418 06Standard Practice forRubber and Rubber LaticesNomenclature1This standard is issued under the fixed designation D 1418; 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 par

2、entheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.INTRODUCTIONThe system of designating rubbers and rubber latices in this pract

3、ice was developed in 1955 toreplace designations GR-A, GR-I, GR-M, GR-S and GR-T (standing for “Government Rubber”:A-acrylontrile, I-isobutylene, S-styrene, M-monochlorobutadiene and T-thiosulfide), used for syn-thetic rubbers made in government owned plants. The system was designed to be a genericc

4、lassification of the rubber polymers that would accommodate both existing and future rubbers. Thechemical composition of the polymer chain was selected as the best classification proposal to achievethis goal. The rubber polymers were divided into eight classes as described in Section 3 of thispracti

5、ce. The letter symbol for the class was given last in the designation for the rubber. Preceding theclass symbol were letter symbols to designate either the monomers used to prepare the polymer or thesubstituent groups on the polymer chain. The system has been successful both in accommodating themany

6、 new polymers developed since 1955 and in conveying to the user certain characteristics of therubber associated with the chemical composition.1. Scope1.1 This practice covers a system of general classificationfor the basic rubbers both in dry and latex forms determinedfrom the chemical composition o

7、f the polymer chain.1.2 The purpose of this practice is to provide a standardiza-tion of terms for use in industry, commerce, and governmentand is not intended to conflict with but rather to act as asupplement to existing trade names and trademarks.1.3 In technical papers or presentations the name o

8、f thepolymer should be used if possible. The symbols can followthe chemical name for use in later references.NOTE 1For terms related to thermoplastic elastomers, see PracticeD 5538.2. Referenced Documents2.1 ASTM Standards:2D 5538 Practice for Thermoplastic ElastomersTerminology and Abbreviations3.

9、Rubbers3.1 Rubbers in both dry and latex form shall be classifiedand coded from the chemical composition of the polymer chainin the following manner:MRubbers having a saturated chain of the polymethylenetype.NRubbers having nitrogen, but not oxygen or phosphorus,in the polymer chain.ORubbers having
