Melt Flow and HDT/Vicat
The melt-flow test detailed in the ASTM D1238 and ISO 1133 standards quickly measures one point on the viscosity curve under standard conditions. While the relative simplicity of this test has remained the same, melt indexers have evolved considerably since they appeared in the 1950s.
Tinius Olsen manufactures two models that perform Deflection Temperature Under Load (DTUL, also called Heat Distortion) and Vicat penetration tests, with six and three test stations respectively. The larger machine can test up to six different specimens simultaneously, with an automated test sequence that proceeds according to user programmed control and configuration parameters.
