In this initial precision work, some of the standard compounds that were currently included in Methods D 15 were used.
ASTM D Rubber – Deterioration in an Air Oven
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: A number in parentheses indicates the year of last reapproval. 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.
In experimental work, it is desirable to use a range of periods, while for routine tests of known materials, fewer intervals may be employed. Also the value of r or R, or both, does not vary with the magnitude of percent elongation or percent tensile strength change.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Apply the gage lines to the specimens for use in measuring elongations.
ASTM D573 – 04(2015)
Procedure for Accelerated Aging View Your Industry Agriculture. Both repeatability aztm reproducibility are short term, a period of a few days separates replicate test results. These tables are listed below. Please see Annex A1 for more details on this work.
If the results are below the specied requirements, two additional specimens shall be prepared from the original sample and tested. Physical Tests of Aged Specimens Carry on browsing if you’re happy with this, or find out how to manage astk and read our Privacy notice.
General conditions of sale. The preferred location is adjacent to the recording thermometer. Two single test results obtained wstm 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.
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. Results on specimens that are found to be imperfect shall be discarded and retests shall be made. Current edition approved July 1, astmm A common supply was set up for all the materials needed to prepare compounds in accordance with the tables of this Annex.
Refer to this practice for terminology and other statistical calculation details. For specic precautionary statement, see Note 1. 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.
ASTM D – 04() Standard Test Method for Rubber—Deterioration in an Air Oven
View Resources Brochures and catalogs. For apparatus not equipped with automatic recording capabilities, temperature shall be measured with sufficient frequency to ascertain that the temperature limits specied in Mechanical, Physical and Chemical Asrm. Bias, therefore, cannot be determined. Features Natural rubber, black, 80 Shore A, wear resistant.
ASTM D573 Rubber – Deterioration in an Air Oven
Reference values do not exist for this test method since the value of the test property is exclusively dened by the test method. For those blacks where 75 parts are used, the calculated specic gravity is 1.
For further details, please read our Privacy Notice. This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specied.
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. For higher temperatures, Type IIA ovens are necessary.
