D Lower Specimen Die. CCSi manufactures these high quality. Contact Supplier Start Order. The surfaces of the die cavity shall either be serrated or contain V-grooves to minimize slippage of the specimen. Viscosity and stress relaxation behavior do not depend on such factors as molecular weight and non-rubber constituents in the same way.
If an exact relationship is required, it should be established for each rubber and set of test conditions. This was a Type 1 precision program; all samples were presented by a single laboratory, and tested without mill massing.
Integrated die cavity, high accuracy. The rotor head shall be securely mounted perpendicularly to a suitable straight cylindrical stem not exceeding 11 mm 0. Historical Version s — view previous versions of standard. Mooney viscosity curve, Mooney s curve, temperature curve of the upper and lower mold 4.
No pronounced increase in r and Ris evident. Feature of Control Software: The test data can be saved automatically 6, astm d 1646 pdf free download. A temperature sensor shall be located in each die for control of the die temperature. The pieces shall be cut from the prepared specimen and astm d 1646 pdf free download be of such dimensions that they will?
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.
Link to Active This link will always route to the current D version of the asgm. Sheet the specimen on the tenth pass. The dimensions of the shearing disk viscometer, test temperatures, and procedures for determining Mooney viscosity are de? A superscript epsilon e indicates an editorial change since the last revision or reapproval.
HYII Mooney Viscometer is used to determine the Mooney dd, scorch time and vulcanization index of astm d 1646 pdf free download rubber, synthetic rubber and regenerated rubber. Viscosity as used in these test methods is not a true viscosity and should be interpreted to mean Mooney viscosity, a measure of shearing torque averaged over a range of shearing rates.
The minimum viscosity and the times for the viscosity to increase by speci? NOTE 10—Resetting torque to a static zero is necessary because the dynamic zero used for the viscosity test would result in a negative torque value once the material wstm completely relaxed with a stationary disk.
When a recorder is not used, astm d 1646 pdf free download, observe the dial indicator or digital display continuously during the s interval preceding the speci? This test method describes the procedure to measure stress relaxation. C Time after the standard 1.
These test methods include procedures for measuring the initial rate of rubber vulcanization. Jinan Qingqiang Technology Co. China viscose waste China 50 cotton 50 viscose China 65 polyester 35 viscose. A greater force may be required to close the dies when tests are made on stocks having extreme toughness. Current edition approved May 10, astm d 1646 pdf free download, Stress relaxation is also a function of the test configuration and for these test methods the results are unique to the Mooney viscometer.
A 5 area under the relaxation curve from to to the end of tf the stress relaxation test Mooney units-secondsand to 5 beginning time of the stress relaxation test, s, and. They shall extend from the 7-mm 0. The use of this or any other reference rubber shall not be used as a substitute for mechanical calibration as described in this section of the standard.
Thus both of these tests are important and complement each aztm. The x test time: The Mooney viscosity is measured by a metal disk embedded in a rubber specimen contained in a astn cylindrical cavity maintained at a speci? In addition to a few insignificant differences there are major technical differences between ISO and this test method in that ISO does not provide for sample preparation on a mill, while this test method allows milling sample preparation in some cases prior to running a Mooney viscosity test.
Viscosity and stress relaxation behavior do not depend on such factors as molecular mass and non-rubber constituents in the same way. The large rotor shall be Any rotor worn to such an extent that the rotor diameter is less than the minimum diameter shown in this procedure shall not be used.
See Practice D The dimensions of the shearing disk viscometer, test temperatures, and procedures for determining Mooney viscosity are defined in these test methods. They shall be fabricated from a nondeforming tool steel, shall have an unplated? NOTE 1—Viscosity as used in these test methods is not a true viscosity and should be interpreted to mean Mooney viscosity, astm d 1646 pdf free download, a measure of shearing torque averaged over a range of shearing rates.
For the r and Rstatements, the difference in the two single test results is expressed as a percentage of the arithmetic mean of the two results. This website uses cookies to improve your experience while you astm d 1646 pdf free download through the website.
