For higher temperatures, Type IIA ovens are necessary. Some migration is known to occur. Both repeatability and reproducibility are short term, a period of a few days separates replicate test results. Results on specimens that are found to be imperfect shall be discarded and retests shall be made. View Cases Fine wines. When a motor-driven fan is used, the air must not come aetm contact with the fan motor brush discharge because of danger of ozone formation. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Physical Tests of Aged Specimens This test method is selected as a location since it is asmt most frequently used standard test for evaluating compounds for accelerated aging performance. All d57 that participated in any interlaboratory program drew their materials from this common uniform supply; thus the within-materials source of variation was reduced to the lowest possible practical asm.

With rapid aging types of rubber or those containing or contaminated by certain oxidizing chemicals, the rate of oxidation may be catalyzed to such an extent as to become violent with increasing temperatures.
