ASTM D – 04() – Standard Test Method for Rubber-Deterioration in an Air Oven
In experimental work, it is desirable to use a range of periods, while for routine tests of known materials, fewer intervals may be employed. Weigh ingredients to nearest 0. Get in contact with us Please give us your feedback using this form. Their form shall be such that no mechanical, chemical, or heat treatment will be required after exposure. Good abrasion and tear resistance black 80 NR Good shock impact and cut resistance Good heat and ageing resistance. Intervals frequently used are 3, 7, and 14 days.
In this initial precision work, some of the standard compounds that were currently included in Methods D 15 were used. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specied.

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. This test method is selected as a location since it is the most frequently used standard test for evaluating compounds for accelerated aging performance. Mechanical fixing with bolts and profiles. If possible, avoid simultaneous aging of a mixed group of different compounds.
The values given in parentheses are for information only.
Last previous edition approved in as D — 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 ast, of the astmm for the ve specimens shall be used: Your web site address. 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 astmm 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 Cases Fine wines. If any adjustments for example, to thickness are necessary, they should be performed prior to exposure. For those blacks where 75 parts are used, the calculated specic gravity is 1.
ASTM D573 – 04(2015)
Refer to this practice for terminology and other statistical calculation details. Carry on browsing if you’re happy with this, or find out how to manage cookies and read our Privacy notice. Astk the results are below the specied requirements, two additional specimens shall be prepared from the original sample and tested. 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.
Also the value of r or R, or both, does not vary with the magnitude of percent elongation or percent tensile strength change. IRB or Industry Reference Black may be used as a suitable alternative, but the same results may not be obtained. Trelleborg Customer Web Portal. These are compared with the properties determined on the original specimens and the changes noted. 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.
Some migration is known to occur. We’re sorry, there was an error trying to send your message. 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.
Only specimens of similar dimensions having approximately the same exposed areas may be compared with each other. 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.

Advantages Good shock asfm, tear, and abrasion resistance Good heat and ageing resistance Noise and vibration propagation reduction Protection against corrosion High rigidity combined asttm high flexibility ensuring a perfect reinforcement of the rubber blade and a low noise operation when used for snow ploughs application.
Apply the gage lines to the specimens for use in measuring elongations. General conditions of sale. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
No values are given for r or R because of the near zero average values for some of the materials. Current edition approved July 1, 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.
Tests of Unaged Specimens 9. For specic precautionary statement, see Note 1. With rapid aging types of rubber or those containing or contaminated by certain oxidizing chemicals, the rate of oxidation may be catalyzed to such an extent as to become violent with increasing temperatures.
Gage lines used for measuring elongation asrm be applied after the specimens have been aged. Both repeatability and reproducibility are awtm term, a period of a few days separates replicate test results.
Bias, therefore, cannot be determined. A common supply was set up for all the materials needed to prepare compounds in accordance with the tables of this Annex.
The results of this test method may not give an exact correlation with service performance since performance conditions vary widely.
