Method A -the test is completely manual and is sometimes called the “cut-and-weigh” method.
Measurement in g/10min.
Method A/B -this employs a digital encoder. In order to run a method B test, an A/B test MUST be run first to
determine the polymer’s melt density. This test takes both A-type and B-type results to determine melt density.
Measurement in g/cc.
Method B -can be conducted only if material melt density is known as is determined by an A/B type test. This is a
“no-cuts” test that is the most convenient for busy laboratories. Measurement in cc/10min.
Method C -can be conducted only if material melt density is known as is determined by an A/B type test. This is also
known as the “half die” method. A half-length die is used and is generally used for testing high flow rate polymers.
This is a “no-cuts” test that is the most convenient for busy laboratories. Measurement in cc/10min.
Method D -can be conducted only if material melt density is known as is determined by an A/B type test. This is
also known as a FRR (Flow Rate Ratio) test. It uses two weights with the same charge of material to determine the
materials FRR. The FRR is the ratio of the average flow rate of the material under higher load to the average flow
rate of the material under lower load. This is a “no-cuts” test that is the most convenient for busy laboratories.
Measurement is unit-less ratio.
