When a motor-driven fan is used, the air must not come in contact with the fan motor brush discharge because of danger of ozone formation. Located in the upper central portion of the chamber near the asym of the aging specimens.

ASTM D573 Rubber – Deterioration in an Air Oven
If any adjustments for example, to thickness are necessary, they should be performed prior to exposure. No values are given for r or R because of the near zero average wstm for some of the materials. We’re sorry, there was an error trying to send your message.
Procedure for Accelerated Aging This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specied. Last previous edition approved in as D — A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Originally approved in Tests of Unaged Specimens 9. Gage lines used for measuring elongation shall be applied after the specimens have been aged.
ASTM D573 – 04(2015)
The values given in parentheses are for information only. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Some migration is known to occur.
Mechanical fixing with bolts and profiles. The preferred location is adjacent to the recording thermometer.
ASTM D – 04() Standard Test Method for Rubber—Deterioration in an Air Oven
For specic precautionary statement, see Note 1. Also the value of r or R, or both, does not vary with the magnitude of percent elongation or percent tensile strength change. Their form shall be such that no mechanical, chemical, or heat treatment will be required after exposure. If possible, avoid simultaneous aging of a mixed group of different compounds. Refer to this practice for terminology and other statistical calculation details.
These are compared with the properties determined on the original specimens and the changes noted. 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Intervals frequently used are 3, 7, and 14 days. This test method may, however, be used to evaluate rubber compounds on a laboratory comparison basis. Physical Tests of Aged Specimens Mechanical, Physical and Chemical Properties.
Apply the gage lines to the dd573 for use in measuring elongations. A common supply was set up asym all the materials needed to prepare compounds in accordance with the tables of this Annex. At least 24 h must elapse between completion of the vulcanization of the samples and the start of the aging test.
After completion of the tests, the broken specimens shall be examined visually and manually and their condition noted. Ashm if the results are below the specied requirements, two additional specimens shall be prepared from the original sample and tested. For higher temperatures, Type IIA ovens are necessary.
View Resources Brochures and catalogs. 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.
