Classification System for Rubber Materials
This classification system tabulates the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications.
Added SAE J2979 for Compression Stress Relaxation as an available suffix in Table 4. Acronym for Compression Stress Relaxation added to table 3. Section 7.1.1 provides a method to use “F” and “SR” callouts that are unavailable in the suffix requirements tables 6AA thru 6KK, since round robins are not available to add these new or revised suffix requirements to J200. Section 8.4 is an example describing how to use “SR” suffix since CSR usually is run as multiple data points at different time intervals to develop a sealing force degradation curve.
