XHY-42E Gardner Type Impact Tester

The Gardner Type Impact Tester can rank materials according to the force required to break flat, rigid plastic samples. This is under specific conditions of impact of a striker and a falling weight.

ASTM D5420

Bench mounted operation

Heavy duty base to withstand the impact shock

Steel rod impact mass

Specimen support plate

Hardened steel striker with a rounded nose

Weights: 0.9kg (2Lb), 1.8kg (4Lb) and 3.6kg (8Lb)

Slotted guide tube (1.0m / 40” in length), in which the impact mass slides.

Bracket holds the tube in a vertical position by attaching it to the base

For Geometries GA, GB and GC, a specimen of 15.86mm ± 0.1mm (0.625” ± 0.004”)

With Geometries GA and GD, a specimen support plate with a hole 76mm ± 3.0mm (3.0” ± 0.12”) in diameter is mounted in the apparatus.

The Gardner Type Impact Tester consists of the following:

A suitable base to withstand the impact shock.

2 Steel rod impact masses weighing 0.9kg, 1.8kg, 3.6Kgs

2 Hardened steel strikers having rounded nose diameters of 15.86 ± 0.10mm and 12.70 ± 0.10mm.

A slotted guide tube of 1.2m in length in which the mass slides, having graduations of 10mm (Marked Length: 1m)

A clamping system to hold the tube vertically in the supporting arm of the base.

A holder for the hand knob which in turn acts as a pivot arm alignment.

A pivot arm for the striker, which is located about 50mm under the tube.

Specimen support plates with hole diameters of 76.0mm ± 3.0mm, 31.75mm ± 0.025mm and 16.26 ± 0.025mm
