Anotace

These test methods cover the qualitative and quantitative analyses of the composition of natural and synthetic crude rubbers. These methods are divided into general and specific test methods. General test methods shall be performed to determine the amount and type of some or all of the major constituents of a rubber product, and shall include determination of rubber polymer content by the indirect method, determination of density, and extract, sulfur, fillers, and ash analyses. Specific test methods, on the other hand, shall be performed to determine specific rubber polymers present in a rubber product such as crude, unvulcanized, reclaimed, and vulcanized rubbers.
