Attempts to develop a full precision and bias statement for this test method have not been successful. They shall be stored for a minimum of 24 h at the standard laboratory temperature, before breaking the seal on the container. Proceed to Checkout Continue Shopping. You currently cannot view this content. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. D — 09 sufficiently accurate for determining transfer pressure.
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.
This time will vary with the compound under test. Need more than one copy? It is especially suited for those compounds used for encapsulation or other low pressure molding techniques. Conversion to SI units can readily be made by multiplying the flow length, in inches, by the appropriate conversion factor, 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.
NOTE 5—Preforms or pellets may be used if found necessary; however, flow length may be affected by their use. You may delete a document from your Alert Profile at any time.

No items in cart. Read the spiral flow length directly from the molded specimen at the point of farthest continuous flow to the nearest 0. Note 1—There is satm known ISO equivalent to this test method. This standard is not included in any packages. September 1, 1 Updated ISO equivalency statement. NOTE 4—There axtm considerable evidence that the test is usable over a wider range of flow lengths, but this has not yet been confirmed by interlaboratory testing.
If you like to setup a quick demo, let us know at support madcad. The electronic file may not be reproduced in any way. Last previous edition approved in as D – 98 Measure the temperature in accordance with the procedures described in Practice D or by thermocouples attached to the mold and plunger. No further reproductions authorized. Remember me for one month. It involves the use ast, a standard spiral flow mold in a transfer molding press under specified conditions of applied temperature and pressure with a controlled charge mass.

It involves the use of a standard spiral flow mold in a transfer molding press under specified conditions of applied temperature and pressure with satm controlled charge mass. NOTE 3—Since the only commercially available molds are calibrated in inches, spiral-flow length will be reported in these units.
Typical examples are presses with pot diameters of Precision and Bias No further reproductions authorized. Because this test method does not contain a round-robin-based numerical precision and bias statement, it shall not be used as a referee test method in case of dispute.
