The elapsed time between insertion of the charge into the pot and the development of pressure on the charge by the plunger shall be no more than 5 seconds. Originally approved in Please sign into an account with a subscription to this content, or email for help at support madcad.

The actual transfer pressure d1323 then calculated as pascals or pounds per square inch by dividing the force in newtons or axtm by the plunger area in square adtm or square inches. Add to Alert PDF. Please login to your authorized staff account to use this feature.

Measure the temperature in accordance with the procedures described in Practice D or by thermocouples attached to the mold and plunger.

It involves the use of a standard spiral flow mold in a transfer molding press under specified conditions of applied temperature axtm pressure with a controlled charge mass. NOTE 4—There is considerable evidence that the test is usable over a wider range of flow lengths, but this has not yet been confirmed by interlaboratory testing.

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by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Remember me for one month. They shall be stored for a minimum of 24 h at the standard laboratory temperature, before breaking the seal on the container.


This standard is not included in any packages. NOTE 5—Preforms or pellets may be used if found necessary; however, flow length may be affected by their use. For this reason, data on precision awtm bias cannot be given.

Your Alert Profile lists the documents that will be monitored. 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.

However, a few well-documented cases are recorded where differences in pot diameters, even within this listed range, have caused large awtm in flow-length readings. We have no document history for this standard.

No further reproductions authorized. Asttm preliminary moldings shall be made with the material to be tested to purge the helical runner before beginning the test. Attempts to develop a full precision and bias statement for this test method have not been successful. It is especially suited for those compounds used for encapsulation or other low pressure molding techniques.

The use of excessive amounts of compound will result in shorter, inconsistent spiral flows. Therefore, for best interlaboratory correlation it is recommended that identical pot diameters be sstm.
