Dd3364 sensitivity of the material to temperature necessitates slightly tighter controls than those stated in Test Method D This means that the? The cause of this unstable condition should be studied and understood.
If the difference between the two specimens is greater than 0. Put the die hot into methyl ethyl ketone in order to break the PVC skin away from the ori?
If you feel that your comments have not d364 a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Viscosity Shear Rate 1? The dimensions of the regular die are shown in Fig.
ASTM D3364 – 99(2011)
Rheological instability due to nonuniform distributions of widely different viscosity or molecular weight elements. ASTM International takes no position respecting the adtm of any patent rights asserted in connection with any item mentioned in this standard. The value for the instability will then be positive or negative.

ASTM D Flow Rates for Poly Vinyl Chloride – Instron
However, as a one-point measure of flow relative to shear rate, its one asstm is that the same PVC melt flow values sstm be obtained for materials having different processibility; the chance of this happening is minimized, however, if the compounds are similar in composition. The sensitivity of this test method makes it useful for correlating with processing conditions and as an aid in predicting changes in processing.
A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Divide the difference by the average and multiply by Many PVC compounds are elastic in nature, causing a severe loss in pressure from the bottom of the piston through the material to the ori? Link to Active This link will always route to the current Active version of the standard.

This may be dd3364 to variable lubricant conditions at the metal surfaces or chemical changes astj the PVC compound. It may be necessary to reshape the end of the cutoff tool to obtain the best results. A clean sharp cut is desirable so that succeeding portions will extrude straight, not curled. Users of this test method should apply the principles outlined in Practice E to generate data speci?
