high accuracy ASTM D639-81 falling ball impact test machine device
high accuracy ASTM D639-81 falling ball impact test machine device
Standard:
ASTM D639-81(1985): STANDARD methods of testing for impact resistance of plats and pats made from engineering plastic rigid plastics by a ball(falling ball)
Working principle:
On the lift beams, equipped with a control device for controlling the falling ball, release the ball, the impact of the sample, so that to achieve the purpose of testing.
Impact energy can be calculated according to the weight and height of the ball. After the ball impact of the sample, produce rebound, the deivice control the ball, to achieve the purpose of preventing secondary shocks.
