I. Introductions:
The machine is used to test the elasticity of rubber material with a free drop hammer.
First adjust the level of the instrument, and then lift the drop hammer to a certain height. When placing the test piece, attention should be paid to making the drop point 14mm away from the edge of the test piece.
The average rebound height of the fourth, fifth and sixth tests was recorded, excluding the first three tests.
II.Main functions:
The machine adopts the standard test method of rubber characteristics.
The elastic rebound rate of rubber was determined by vertical rebound method.
III. Reference Standard:
ASTM D2632 and other standards.
IV. Instrument characteristics:
RHand dial type release, the operation is simple;
RBring visual frame, can be adjusted up and down;
