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.
Thus, implications with respect to PVC molecular structural changes can be detected and predicted. Glossary of Materials Testing Terms. Correlations with a wide range of processing conditions have supported the conclusions that little or no change in composition occurs during the test.
The data in Table 3 should not be rigorously applied asym acceptance or rejection of material, as those data are speci?
ASTM D3364 – 99(2011)
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Current edition approved March 10, The entire time of charging and positioning of weights should take no longer than 1 min and preferably less than 1?
NOTE 3—Occasionally, the values change throughout the run. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Each laboratory obtained three test results for each material. It may be necessary to reshape the end of the cutoff tool to obtain d33644 best results. Temperature Total load on piston Approximate pressure Charge Plugged ori? Each test result was the average of? Be careful not to squeeze the specimen; the specimen should?
Precision and Bias Note 1—There is no known ISO equivalent to this standard. This test method is useful for quality-control tests on PVC compounds having a wide 3d364 of melt viscosities.
ASTMD Standard Test Method for Poly(Vinyl ride) with Molecular Structural Implications_百度文库
Rheological instability due to nonuniform distributions of widely different viscosity or molecular weight elements. If instability still occurs, particularly at high? How can we help you? Most asfm designed for Test Method D cannot control better than Description Contact Us This test method is used for quality-control tests on PVC compounds that have a wide range of melt viscosities. Fluctuations up and down repeatedly during a run can indicate nonuniform mixing or a bad charging technique.
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 Flow Rates for Poly Vinyl Chloride – Instron
Thus, this test is able to detect and follow profound changes which occur during v3364, injection molding, milling, or mixing.
This test method is used for quality-control tests on PVC compounds that have a wide range of melt viscosities. Measurements are made at shear rates close to 1 s?
Email addresses can only contain letters, numbers and the following special characters: These changes are due to three types of measured instability in polymers:.
The following explanations of r and R Next Checking to see if you are a returning visitor…. Concrete, Asphalt and Rock.
The quantity of material introduced into the barrel is 2. The sensitivity of this test method makes it useful for correlating with processing conditions and as an aid in predicting changes in processing.
