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.
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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Trelleborg Customer Web Portal. In this initial precision work, some of the standard compounds that were currently included in Methods D 15 were used. 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.
For those blacks where 75 parts are used, the calculated specic gravity is 1. We’re sorry, there was an error trying to send your message. Their form shall be such that no mechanical, chemical, or heat treatment will be required after exposure. A number in parentheses indicates the year of last reapproval.
For specic precautionary statement, see Note 1. Results on specimens that are found to be imperfect shall be discarded and retests shall be made. 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. Please see Annex A1 for more details on this work. For further details, please read our Privacy Notice. Reference values do not exist for this test method since the value of the test property is exclusively dened by the test method.
Refer to this practice for terminology and other statistical calculation details. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Number of Test Specimens 8. 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.
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.
Summary of Test Method 3. Gage lines used for measuring elongation shall be applied after the specimens have been aged.
ASTM D573 – 04(2015)
Intervals frequently used are 3, 7, and 14 days. IRB or Industry Asym Black may be used as a suitable alternative, but the same results may not be obtained. Good shock impact, tear, and abrasion resistance Good heat and ageing resistance Noise and vibration propagation d5773 Protection against corrosion High rigidity combined with high astmm ensuring a perfect reinforcement of the rubber blade and a low noise operation when used for snow ploughs application.
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: Both repeatability and reproducibility are short term, a period of a few days separates replicate test results.
For higher temperatures, Type IIA ovens are necessary. Features Natural rubber, black, 80 Shore A, wear resistant. These are compared with the properties determined on the original specimens and the changes noted.
The values given in parentheses are for information only. Your comments are invited either for revision of this d5573 or for additional standards and should be addressed to ASTM International Headquarters. View Cases Fine wines.
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. No values are given for r or R because of the near zero average values for some of the materials. This test method may, however, be used to evaluate rubber compounds on a laboratory comparison basis. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
ASTM D – AIR OVEN DETERIORATION
Physical Tests of Aged Specimens At least 24 h must wstm between completion of the vulcanization of the samples and the start of the aging test. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. View About Us Join the Team.
These tables are listed below.
Wrapping Black polyethylene film. Tests of Unaged Specimens 9. If you feel that your comments have not received a fair hearing you should make asmt views known to the ASTM Committee on Standards, at the address shown below. The selection of suitable asmt of aging will depend on the rate of deterioration of the particular material being tested. Mechanical, Physical and Chemical Properties. This test method is selected as a location since it is the most frequently used standard test for evaluating compounds for accelerated aging performance.
