The following grid lists the types of testing offered by independent testing laboratories. Tests for physical testing of rubber include stress/strain tests; time-dependent tests; destructive tests; durability; electrical properties and processing. Tests for chemical analysis of raw materials and rubber are broken down into spectrophotometry, spectrometry and spectroscopy; chromatography; thermal analysis; and microscopy. Each of these subdivisions is further broken down into the specific type of tests.
