ASTM D – 04() Standard Test Method for Rubber—Deterioration in an Air Oven
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Current edition approved July 1, This test method is selected as a location since it is the most frequently used standard test for evaluating compounds for accelerated aging performance.
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: 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. In this initial precision work, some of the standard compounds that were currently included in Methods D 15 were used. These tables are listed below.
ASTM D573 Rubber – Deterioration in an Air Oven
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.
For specic precautionary statement, see Note 1. With rapid aging types of rubber or those containing or contaminated by certain oxidizing chemicals, awtm rate of oxidation may be catalyzed to such an extent as to become violent with increasing temperatures. If possible, avoid simultaneous aging of a mixed group of different compounds.
S573 common supply was set up for all the materials needed to prepare compounds in accordance with the tables of this Annex.
This test method may, however, be used to evaluate rubber compounds on a laboratory comparison basis. 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.
Results on specimens that are found to be imperfect shall be discarded and retests shall be made.
Number of Test Specimens 8. Please see Annex A1 for more details on this work. Both repeatability and reproducibility are short term, a period of a few days separates replicate test results. View Resources Brochures and catalogs. These are compared with the properties determined on the original specimens and the changes noted. A number in parentheses indicates the year of last reapproval. Weigh ingredients to nearest 0.
Signicance and Use 4.
No values are given for r or R because of the near zero average values for some of the materials. 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.

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 d5733 mechanical, chemical, or heat treatment will be required after exposure.
For apparatus not equipped with automatic recording capabilities, temperature shall be measured with sufficient frequency to ascertain that the temperature limits specied in At least 24 h must elapse between completion of the vulcanization of the samples and the start of the aging test.
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. Trelleborg Customer Web Portal. The appropriate value is that value of r or R associated with a mean level in the 5d73 tables closest to the mean level under consideration at any given time, for any given material in routine ast, operation.

Originally approved in 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 dd573 their own responsibility. Tests of Unaged Specimens 9. Reference values do not exist for this test method since the value of the test property is exclusively dened by the test method.
Mechanical fixing with bolts and profiles.
