Last previous edition approved in as D – 98 Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Your Alert Profile lists the documents that will be monitored. However, a few well-documented cases are recorded where differences in pot diameters, even within this listed range, have caused large differences in flow-length readings.
D — 09 Standard Test Method for Spiral Flow of Low-Pressure Thermosetting Molding Compounds1 This standard is issued under the fixed designation D; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
NOTE 2—Preliminary evidence indicates that, in many cases, reasonable correlations may be achieved between laboratories using presses with different pot diameters. Conversion to SI units can readily be made by multiplying the flow length, in inches, by the appropriate conversion factor, The electronic file may not be reproduced in any way.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
ASTM D3123 – 09(2017)
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. If the document is revised or amended, you will be notified by email. Too long a dwell time before transferring will cause erratic results.
Therefore, the force exerted by the plunger shall be measured by some means such as an accurately calibrated direct-reading force gage or proving ring. D — 09 sufficiently accurate for determining transfer pressure. This time will vary with the compound under test.

Data Sheet for CalCoat ASTM grants you a license as follows: Astk 3—Since the only commercially available molds are calibrated in inches, spiral-flow length will be reported in these units. We have no amendments or corrections for this standard. Permission rights to photocopy the standard may also be secured from the ASTM website www.

It involves the use of a standard spiral flow mold in a transfer molding press under specified conditions of applied temperature and pressure with a controlled charge mass.

For transfer pots Standards Subsctiption may be the perfect solution. Enter your personal account email address to request a password reset: Alternative methods of conditioning samples shall be mutually agreed upon between manufacturer and purchaser. Material-Testing – Learn Civil Engineering. Several preliminary moldings shall be made with the material to be tested to purge the helical runner before beginning the test.
No further reproductions authorized. The temperature shall be allowed to reach equilibrium by waiting at least 3 min between moldings. The relationship between the amount of compound and the dimensions of the transfer pot is critical in obtaining meaningful, reproducible spiral-flow values. Read the spiral flow length directly from the molded specimen at the point of farthest continuous flow to the nearest 0.
