MFI - ISO1133

Measures flow under a specified weight and at specified temperature (230°C / 2.16kg)

Flexural Modulus - ISO178

Measures the force required to bend a specimen supported near one both ends (23°C, 4mm thickness, 2mm/min speed)

Heat Deflection Temperature - ISO75-2

Measures the temperature at which a specimen, supported at both ends with a force in MPa applied in the centre, deflects by a specified amount.

VICAT Softening Temperature - ISO306

Measures the temperature at which a flat ended needle, of defined cross section and load, penetrates to a define depth.

IZOD impact strength (notched) - ISO180/1A

Measures the energy required to break a specimen supported near one end and struck by a pendulum at a specified temperature.

Brittle point - ISO 974

Measures the temperature at which, a specimen supported near one end and under a specified impact, 50% of brittle failure is obtained (Tf ± Tg)

Multi-axial impact strength (DDT)

Measures the energy absorbed by the specimen (disk, 2mm thickness); it simulates a collision that a functional part might undergo in service!

Transparency - ASTM D 1746

Measures the ratio of transmitted light intensity to the incident light intensity.
