We’re sorry, there was an error trying to send your message. A common supply was set up for all the materials needed to prepare compounds in accordance with the tables of this Annex. Apply the gage lines to the specimens for use in measuring elongations. In this initial precision work, some of the standard compounds that were currently included adtm Methods D 15 were used.

Your web site address. 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. With rapid aging types of rubber or those containing or contaminated by certain astn chemicals, the rate of oxidation may be catalyzed to such an extent as to become violent with increasing temperatures.
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 ast, revision.
General conditions of sale. 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 This test method is selected as a location since it axtm the most frequently used standard test for evaluating compounds for accelerated aging performance.
Number of Test Specimens 8. A test result is expressed on the basis of a median value, as specied by Test Methods D obtained on three determinations or measurements of the property or parameter in question.
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.
Only specimens of similar dimensions having approximately the same exposed areas may be compared with each other. If possible, avoid simultaneous aging of a mixed group of different compounds. Mechanical, Physical and Chemical Properties. This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specied.
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 has been approved for use by agencies of the Department of Defense. All laboratories 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 level.

For specic adtm statement, see Note 1. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Last previous edition approved in as D — Atsm if the results are below the specied requirements, two additional specimens shall be prepared from the original sample and tested.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Located in the upper central portion of the chamber near the center of the aging specimens.
The preferred location is adjacent to the recording thermometer. Both repeatability and d53 are short term, a period of a few days separates replicate test results.

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. No values are given for r or R because of the near zero average values for some of the materials. 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. Signicance and Use 4.

These tables are listed below. After completion of the tests, the broken specimens shall be examined visually and manually and their condition noted. 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.
Their form shall be such that no mechanical, chemical, or heat treatment will be required after exposure. The results of this test method may not give an exact correlation with service performance since performance conditions vary widely. Wrapping Black polyethylene film. For instance, high-sulfur compounds should not be aged with low-sulfur compounds and those containing antioxidants shall not be aged with those having no antioxidants.
Some migration is known to occur.
