Should the results of either of these tests be below the specied requirements, the sample shall be considered to have failed to meet the specications. Results on specimens that are found to be imperfect shall be discarded and retests shall be made.
Their form shall be such that no mechanical, chemical, or heat treatment will be required after exposure. Physical Tests of Aged Specimens 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.
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. View Your Industry Agriculture. Your web site address.
Both repeatability and reproducibility are short term, a period of a few days separates replicate satm results. With rapid aging types of rubber or those containing or contaminated by certain oxidizing chemicals, the wstm of oxidation may be catalyzed to such an extent as to become violent with increasing temperatures.
ASTM D573 – 04(2015)
Reference values do not exist for this test method since the value of the test property is exclusively dened by the test method. This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specied.
Number of Test Specimens 8. View Resources Brochures and catalogs. Good abrasion and tear resistance black 80 NR Good shock impact and cut resistance Good heat and asrm resistance.

Bias, therefore, cannot be determined. The preferred location is adjacent to the recording thermometer. A common supply was set up for all the materials needed atm prepare compounds in accordance with the tables aztm this Annex. Refer to this practice for terminology and other statistical calculation details.
Features Natural rubber, black, 80 Shore A, wear resistant. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. View About Us Join the Team.
Mechanical fixing with bolts and profiles. Mechanical, Physical and Chemical Properties. 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. The selection of suitable intervals of aging will depend on the rate of deterioration of the particular material being tested.
No values are given for r or R because of the near zero average values for some of the materials. View Cases Fine wines. The values given in parentheses are for information only.
Get in contact with us Please give us your feedback using this form. 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.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if e573 revised, either reapproved or withdrawn. If any adjustments for example, to thickness are necessary, they should be performed prior to exposure.
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 astmm designation indicates the year of original adoption or, in the case of revision, the year of last revision.

IRB or Industry Reference Black may satm used as a suitable alternative, but the same results may not be obtained.
If the results are below asym specied requirements, two r573 specimens shall be prepared from the original sample and tested. Current edition approved July 1, Last previous edition approved in as D — Summary of Test Method 3. A number in parentheses indicates the year of last reapproval. 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.
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.

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. 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 aztm ve specimens shall be used: Signicance and Use 4.
This standard has been approved for use by agencies of the Department of Defense. 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.
Located 5d73 the upper central portion of the chamber near the center of the aging specimens. We’re sorry, there was an error trying to send your message. Some migration is known to occur.
