Density Gradient Technique ATM D 1505
Density Gradient Technique ASTM D 1505

Density of a plastic is determined by observing the level in which the material sinks in a column of a known density gradient and is compared to known standards. The density gradient columns shown here provide a “light” column (r <1) and a “heavy” column (r >1).

Density and Specific Gravity (Relative Density) by Displacement ASTM D-702
Density and Specific Gravity (Relative Density)

This test provides a method of determining the specific gravity or relative density of a material (l if not using water as the liquid) of molded or formed parts.  The importance of this test is that this method can be used to help to identify materials and possible follow changes in those materials.

Apparent Bulk Density, Bulk Factor, and Pourability of Plastic Materials ASTM D 1895 Method A
Apparent Bulk Density, Bulk Factor, and Pourabilty of Plastic Materials ASTM D 1895

The method measures the apparent bulk density, bulk factor, and pourabilty of plastic materials such as molding powders typically used in rotational molding. The test values can be used as index of performance with respect to their handling and fabrication.

Melt Flow Rates of Thermoplastics by Extrusion Plastometer ASTM D 1238
Melt Flow Rates of Thermoplastics by Extrusion Plastometer ASTM D1238

The test measures the rate of extrusion of a molten plastic through a die under specific conditions for the given plastic.

Capillary Rheometer ATM D3835
Capillary Rheometer ASTM D3835

Method covers the measurement of the rheological properties of polymeric materials at various temperatures and shear rates common to processing equipment. This test allows for characterization of materials that demonstrate stable and unstable melt viscosity properties.

Enthapies of Fusion and Crystallization of Polymers (DSC) ASTM 3417
Enthalpies of Fusion and Crystallization of Polymers ASTM D 3417

DSC can be used to help to identify materials that exhibit thermal transitions.

Transition Temperature of Polymers (TGA) Thermal Gravimetric Analysis  ASTM D 3418
Transition Temperature of Polymers (TGA) Thermal Gravimetric Analysis  ASTM D 3418

This method can be used to identify chemical reactions that occur during heating. These reactions may include oxidation, curing of thermosets and thermal decomposition.

Heat Distortion Temperature (HDT) or Deflection Temperature (DTUL) ASTM D648
Heat Distortion Temperature (HDT) or Deflection Temperature (DTUL) ASTM D648

This test measures the temperature at which a sample deflects 0.010” under specific conditions.
