Procedure for Accelerated Aging Summary of Test Method 3.
ASTM D573 – 04(2015)
Tests of Unaged Specimens 9. IRB or Industry Reference Black may be used as a suitable alternative, but the same results may not be obtained. For further details, please read our Privacy Notice. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Mechanical fixing with bolts and profiles. After completion of the tests, the broken specimens shall be examined visually and manually and their condition noted.

A common supply was set up for all the materials needed to prepare compounds in accordance with the tables of this Annex. The preferred location is adjacent to the recording thermometer. Both repeatability and reproducibility are short term, a period of a few days separates replicate test results. 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.
Signicance and Use 4. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Apply the gage lines to the specimens for use in measuring elongations.
ASTM D Rubber – Deterioration in an Air Oven
The values given in parentheses are for information only. Features Natural rubber, black, 80 Shore A, wear resistant. 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. General conditions of sale. In this initial precision work, some of the standard compounds that were currently included in Methods D 15 were used.
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. At least 24 h must elapse between completion of the vulcanization of the samples and the start of the aging test. D5733 values do not exist for this test method since the value of the test property awtm exclusively dened by the test method. We’re sorry, there was an error trying to send your message.
The results of this test method may not give an exact correlation with service performance since performance conditions vary widely.
Two single test results, obtained under normal test method procedures, that differ asym more than this tabulated r for any ast, level must be considered as derived from different or non-identical sample populations.
This standard has been approved for use by agencies of the Department of Defense. 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.
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. Number of Test Specimens 8. For specic precautionary statement, see Note 1. 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. 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. View Cases Fine wines.
If any adjustments for example, to thickness are necessary, they should be performed prior to exposure. 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. For those blacks where 75 parts are used, the calculated specic gravity is 1. Benefits Efficiency Safety Comfort Reliability.
Good abrasion and tear resistance black 80 NR Good shock impact and cut resistance Good heat and ageing resistance. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
