Chemical Analysis Test Procedures for Rubber Products


The test methods in this standard are used to determine the chemical composition in natural and synthetic crude rubbers. There are two categories of test methods used:

  • General tests – used to identify the type and amount of chemical components that exist in a rubber product and identifies the rubber polymer content (via ASTM D792)
  • Specific tests – used to identify specific rubber polymers that are present in a rubber product including crude, unvulcanized, reclaimed, and vulcanized rubbers

Test Details

General test methods are covered in Part A of the standard. They are listed as the following:

  • Rubber Polymer Content by Indirect Method (via ASTM D792)
  • Determinations and Report for the General Method
  • Density
  • Extract Analysis
  • Sulfur Analysis
  • Fillers Analysis
  • Ash Analysis

Specific test methods are covered in Part B of the standard and include Determination of Rubber Polymers.

*Please Note: The information outlined above is to be used as reference ASTM D297 Standard Test Method for Rubber Products – Chemical Analysis. Please refer to ASTM International for full details and the most current revision.
