These tables are listed below. We’re sorry, there was an error trying to send your message. This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specied. Their form shall be such that no mechanical, chemical, or heat treatment will be required after exposure. Bias, therefore, cannot be determined. 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 apparatus not equipped with automatic recording capabilities, temperature shall be measured with sufficient frequency to ascertain that the temperature limits specied in 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. Originally approved in After completion of the tests, the broken specimens shall be examined visually and manually and their condition noted.
Physical Tests of Aged Specimens If the results are below the specied requirements, two additional specimens shall be prepared from the original sample and tested. Reference values do not exist for this test method since the value of the test property is exclusively dened by the test method.
If any adjustments for example, to thickness are necessary, they should be performed prior to exposure. In determining the physical properties after aging, the nal values shall be the median of results from three specimens except that under the following conditions two additional specimens shall be exposed and tested and the median of the values for the ve specimens shall be used: Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Summary of Test Method 3. This test method is selected as a location since it is the most frequently used standard test for evaluating compounds for accelerated aging performance.
ASTM D – AIR OVEN DETERIORATION
In experimental work, it is desirable to use a range of periods, while for routine tests of known materials, fewer intervals may be employed.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Two single test results, obtained under normal test method procedures, that differ by more than this tabulated r for any given level must be considered as derived from different or non-identical sample populations.
Should the results of either of these tests be below d57 specied requirements, the sample shall be considered to have failed to meet the specications. Also the value of r or R, or both, does not vary with the magnitude of percent elongation or percent tensile strength change. View Cases Fine wines. For specic precautionary statement, see Note 1. Only specimens of similar dimensions having approximately the same exposed areas may be compared with each other.

General conditions of sale. View About Us Join the Team. Two single atm results obtained in two different laboratories, under normal test method procedures, that differ by more than the tabulated R for any given level must be considered to have come from different or nonidentical sample populations. Some migration is known to occur. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Trelleborg Customer Web Portal. If possible, avoid simultaneous aging of a mixed group of different compounds. D — 04 Standard Test Method for Rubber—Deterioration in an Air Oven1 This standard is issued under the xed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Procedure for Accelerated Aging A common supply was set up for all the materials needed to prepare compounds in accordance with the tables of this Annex. But if the results are below the specied requirements, two d73 specimens shall be prepared from the original sample and tested.
Intervals d537 used are 3, 7, and 14 days. These are compared with the properties determined on the original specimens and the changes noted.
The appropriate value is that value of r or R associated with a mean level in the precision tables closest to the mean level under consideration at any given time, for any given material in routine testing operation.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Results on specimens that are found to be imperfect shall be discarded and retests shall be made.
