If the results are below the specied requirements, two additional specimens shall be prepared from the original sample and tested.
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. If possible, avoid simultaneous aging of a mixed group of different compounds. No values are given for r or R because of the near zero average values for some of the materials. Wrapping Black polyethylene film. In experimental work, it is desirable to use a range of periods, while for routine tests of known materials, fewer intervals may be employed.
Reference values do not exist for this test method since the value of the test property is exclusively dened by the test method. Their form shall be such that no mechanical, chemical, or heat treatment will be required after exposure. 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.
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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. 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.
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. Gage lines used for measuring elongation shall be applied after the specimens have been aged.
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: View Resources Brochures and catalogs.
Good shock impact, tear, and abrasion resistance Good heat and ageing resistance Noise aastm 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.
ASTM D – 04() – Standard Test Method for Rubber-Deterioration in an Air Oven
Originally approved in IRB or Industry Reference Black may be used as a suitable alternative, but the same results may not be obtained. These are compared with the properties determined on the original specimens and the changes noted.
Summary of Test Method 3. Get in contact with us Please give us your feedback using this form. Trelleborg Customer Asrm Portal.
But if the results are below the specied requirements, two additional specimens shall be prepared from the adtm sample and tested. Results on specimens that are found to be imperfect shall be discarded and retests shall be made. Refer to this practice for terminology and other statistical calculation details.
For those blacks where 75 parts are used, the calculated specic gravity is 1. Some migration is known to occur.
ASTM D573 Rubber – Deterioration in an Air Oven
A common supply was set up for all the dd573 needed to prepare compounds in accordance with the tables of this Annex. View About Us Join the Team. Users of this standard are expressly advised that determination f573 the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The selection of suitable intervals of aging will depend on the rate of deterioration of the particular material being tested.
For specic precautionary statement, see Note 1.
ASTM D573 – 04(2015)
Precision and Bias 4 After completion of the tests, the broken specimens shall be examined visually and manually and their condition noted. Carry on browsing if you’re happy with this, or find out how to manage cookies and read our Privacy notice. 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.
If any adjustments for example, to thickness are necessary, they should be performed prior to exposure. For further details, please v573 our Privacy Notice.
At least 24 h must elapse between completion of the vulcanization of the samples and the start of the aging test. For apparatus not equipped with automatic recording capabilities, temperature shall be measured with sufficient frequency to ascertain that the temperature limits specied in
