A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. Scope 1. The results of this test method may not give an exact correlation with service performance since performance conditions vary widely.

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.
Please see Annex A1 for more details on this work. A common supply was set up for all the materials needed to prepare compounds in accordance with the tables of this Annex. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. For further details, please read our Privacy Notice. At least 24 h must elapse between completion of the vulcanization of the samples and the start of the aging test.
Precision and Bias 4 Tests of Unaged Specimens 9. 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.
Should the results of either of these tests be below the specied requirements, the samples shall be considered to have failed to meet the specications. A number in parentheses indicates the year of last reapproval. Should the results of either of these tests be below the specied dd, the sample shall be considered to have failed to meet the specications. Last previous edition approved in as D — For apparatus not equipped with automatic recording capabilities, temperature shall be measured with sufficient frequency to ascertain that the temperature limits specied in For those blacks where 75 parts are used, the calculated specic gravity is 1.
ASTM D — 04 If any adjustments for example, to thickness are necessary, s should be performed prior to exposure. When submitting this form, you are aware of that we will process the personal data that you give us in order to facilitate your request. This test method may, however, be used to evaluate rubber compounds on a laboratory comparison basis. In this initial precision work, some of the standard compounds that were currently included in Methods D 15 were used. Trelleborg Customer Web Portal.
