Apply the gage lines to the specimens for use in measuring elongations. 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. The results of this test method may not give an exact correlation with service performance since performance conditions vary widely.
ASTM D – AIR OVEN DETERIORATION
If any adjustments for example, to thickness are necessary, they should be performed prior to exposure. Results on specimens that are found to be imperfect shall be discarded and retests shall be made. Last previous edition approved in as Awtm — A number in parentheses indicates the c573 of last reapproval.
Benefits Efficiency Safety Comfort Reliability. 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: Two single test results, obtained satm normal test method procedures, that differ by more than this tabulated r for any given level must be considered as derived from different or non-identical sample populations.
When astn motor-driven fan is used, the air must not come in contact with the fan motor brush discharge because of danger of ozone formation. View Your Industry Agriculture. View About Us Join the Team. View Cases Fine wines. This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specied.
The preferred location is adjacent to the recording thermometer. Mechanical, Physical and Chemical Properties. These tables are listed below. No values are given for r or R because of the near zero average values for d753 of the materials. Procedure for Accelerated Aging Summary of Test Method 3. We’re sorry, there was an error trying to send your message. Wrapping Black polyethylene film.
All laboratories that astn 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. 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. Trelleborg Customer Web Portal. Their form shall be such that no asym, chemical, or heat treatment will be required after exposure.
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 experimental work, it is desirable to use a range of periods, while for routine tests of known materials, fewer intervals may be employed.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
ASTM D573 Rubber – Deterioration in an Air Oven
Mechanical fixing with bolts and profiles. Precision and Bias 4 Only specimens of similar dimensions having approximately the same exposed areas may be compared with each other. Features Natural rubber, black, 80 Shore A, wear resistant. Advantages 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.
Physical Tests of Aged Specimens Number of Test Specimens 8. 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 the designation indicates the year of original adoption or, in the case of revision, the year of last revision. Reference values do not exist for this test method since the value of the test property is exclusively dened by the test method.
But if the results are below the specied requirements, two additional specimens shall be prepared from the original sample and tested. Your web site address. Weigh ingredients to nearest 0. Good abrasion and tear resistance black 80 NR Good shock impact and cut resistance Good heat and ageing resistance. After completion of the tests, the broken specimens shall be examined visually and manually and their condition noted.
