ASTM D3123 – 09(2017)

The relationship between the amount of compound and the dimensions of the transfer pot is critical in obtaining meaningful, reproducible spiral-flow values. ASTM grants you a license as follows: Note 1—There is no known ISO equivalent to this test method.

This standard is also available to atsm included in Standards Subscriptions.

Significance and Use 4. Permission rights to photocopy the standard may also be secured from the ASTM website www.

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.

Measure the temperature in accordance with the procedures described aatm 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 and pressure with a controlled charge mass.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Several preliminary moldings shall be made with the material to be tested to purge the helical runner before beginning the test. As the voice of the U. The actual transfer pressure is then calculated as pascals or pounds per square inch by dividing the force in newtons or pounds-force by the plunger area in square metres or square inches.

Precision and Bias 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. Remember me for one month. D — 09 sufficiently accurate for determining transfer pressure. Print 1 2 3 4 5 page sstarting from page current page.
