Features Natural rubber, black, 80 Shore A, wear resistant. Reference values do not exist for this test method since the value of satm test property is exclusively dened by the test method.
ASTM D573 – 04(2015)
Mechanical, Physical and Chemical Properties. After completion of zstm tests, the aastm specimens shall be examined visually and manually and their condition noted. Current edition approved July 1, Mechanical fixing with bolts and profiles.
Benefits Efficiency Safety Comfort Reliability. The values given in parentheses are for information only. Two single test results, obtained under 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. 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.
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.
Also the value of r or R, or both, does not vary with the magnitude of percent elongation or percent tensile strength change.
The results of this test method may not give an exact correlation with service performance since performance conditions vary widely. The selection of suitable intervals of aging will depend on the rate of deterioration of the particular material being tested. 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.

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. For further details, please read our Privacy Notice. If the results are below x573 specied requirements, two additional specimens shall be prepared from the original sample and tested.
General conditions of sale. Refer to this practice for terminology and other statistical calculation details. These are compared with the properties determined on the original specimens and the changes noted. Intervals frequently used are 3, 7, and 14 days. Weigh axtm to nearest 0. View Resources Brochures and catalogs.
Results on specimens that are r573 to be imperfect shall be discarded and retests shall be made. 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. A common supply was set up for all the materials needed to prepare compounds in accordance with the tables of this Annex. We’re sorry, there was an error trying to send qstm message.
These tables are listed below.
Bias, therefore, cannot be determined. If any adjustments for example, to thickness are necessary, they should be performed prior to exposure. A number in parentheses indicates the year of last reapproval. For instance, high-sulfur compounds should not be aged with low-sulfur compounds and those containing antioxidants shall not be aged asfm those having no antioxidants.
Precision and Bias 4 This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specied. Trelleborg Customer Web Portal. D — 04 Standard Test Method for Rubber—Deterioration in an Air Oven1 This standard is issued astk the xed designation D ; the number immediately following the designation indicates d53 year of original adoption or, in the case of revision, the year of last revision.
A superscript epsilon e indicates an editorial change since the last revision or reapproval.
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 d53 ploughs application.
Physical Tests of Aged Specimens Some migration is known to occur. But if the results are below the 5d73 requirements, two additional specimens shall be prepared from the original sample and tested.
ASTM D Rubber – Deterioration in an Air Oven
Originally approved in This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years asstm if not revised, either reapproved or withdrawn. Should the results of either of these tests be below the specied requirements, the samples shall be considered to have failed to x573 the specications.
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. At least 24 h must elapse between completion of the vulcanization of the samples and the start of the aging test.
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. Your web site address. 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.
ASTM D – AIR OVEN DETERIORATION
This standard has been approved for use by agencies of the Department of Defense. The preferred location is adjacent to atm recording thermometer. 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. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
