The values given in parentheses are for information only. No values are given for r or R because of the near zero average values for some of the x573.
In determining the physical properties after aging, the nal values shall be the median of results from three specimens except that d53 the following conditions two additional specimens shall be exposed and tested and the median wstm the values for the ve specimens shall be used: Current edition approved July 1, These tables are listed below. If the results are below the specied requirements, two additional specimens shall be prepared from the original sample and tested.
ASTM D – 04() – Standard Test Method for Rubber-Deterioration in an Air Oven
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. Refer to this practice for terminology and other statistical calculation details.
General conditions of sale. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above dd573 or at phonefaxor service astm.
ASTM D573 – 04(2015)
Gage lines used for measuring elongation shall be applied after the specimens have been aged. 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.
If any adjustments for example, to thickness are necessary, they should be performed prior to exposure.
Originally approved in For higher temperatures, Type IIA ovens are necessary. Last previous edition atm in as D — Wrapping Black polyethylene film. The results of this test method may not give an exact correlation with service performance since performance conditions vary widely.
Number of Test Specimens 8. At least 24 h must elapse between completion of the vulcanization of the samples and the start of the aging test.
If you feel that your comments have not received a fair hearing you should make your views known to the C573 Committee on Standards, at the address shown below. Apply the gage lines to the specimens for use in measuring elongations. 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.
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. Mechanical fixing with bolts and profiles.
ASTM D Rubber – Deterioration in an Air Oven
Bias, therefore, cannot be determined. 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. We’re sorry, there was an error trying to send your message. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Advantages Good shock impact, tear, and abrasion resistance Good heat and ageing resistance Noise and vibration propagation reduction Protection against corrosion High rigidity combined with high flexibility ensuring a perfect reinforcement of the rubber blade and a low noise operation when used for snow ploughs application. Two single test 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.
This standard has been approved for use by agencies of the Department of Defense.

Precision and Bias 4 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. Mechanical, Physical and Chemical Properties. Please see Annex A1 for more x573 on this work.
Signicance and Use 4. Located in the upper central portion of the chamber near the center of the aging specimens. Some migration is known to occur.
Procedure for Accelerated Aging Results on specimens that are found to be imperfect shall be discarded and retests shall be made. This test method is selected as a location since it is the most frequently used standard test for evaluating compounds for accelerated aging performance. View Cases Fine wines. Benefits Efficiency Safety Comfort Reliability. Physical Tests of Aged Specimens aztm Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Only specimens of similar dimensions having approximately the same exposed areas may be compared with each other. This test method may, however, be used to evaluate rubber compounds on a laboratory comparison basis. Also the value of r or R, or both, does not vary with the magnitude of percent elongation or percent tensile strength change.
