This test measures the rate of extrusion of molten polymer through a die of specified length and diameter at specified conditions of temperature, load, and piston position in the barrel as a timed measurement is made.

The appearance is compared to a dispersion reference chart. No orders will ship and email response will be delayed during this time.

For those requiring data output for recording and quality documentation purposes, a serial output cable and windows-based software program is optionally available. Laboratory ry X5199 7. Specimens of known size are cut and weighed. The specimen geometry of this test produces a stress concentration in a small area of the specimen.

This test d5919 is designed to measure the force to initiate tearing at a low rate of loading. It is then immersed in liquid, its loss in weight upon immersion is determined and its density calculated.
