27、aboratory tests (ISO/TR 9272) were closely related to ASTM D4483. ISO/TR 9272 was found to have serious flaws which users were using work-arounds to counteract. It became clear that ISO/TR 9272 needed to be replaced and it was concluded that the best option was to base a new standard on ISO 5725 (al
28、l parts) with specific choices and variations of procedures to suit the particular requirements of rubbers.
