Rubber, vulcanized or thermoplastic. Resistance to ozone cracking - Static and dynamic strain testing Ingestion-build-105964 Note4: The test results are1 Scope This part of ISO 1431 specifies procedures intended for use in estimating the resistance of vulcanized or thermoplastic rubbers to cracking when exposed, under static or dynamic tensile strain, to air containing a definite concentration of ozone and at a definite temperature in circumstances that exclude the effects of direct light. Great caution is necessary in attempting to relate standard test results to service performance since the
