Typically the spring loaded impact hammer is 0.5 Joules, the 50mm steel sphere is 5.0 Joules when doing the vertical or pendulum drop.

IEC60950-1 2005 and UL, CSA variation Hi Guys, Can the ball drop test be conducted using impact hammer ? I do not see any credible reason for not using the impact hammer. Impact test using impact hammer delivers x amount of Joules energy upon impact similar to the dropping of steel ball of certain size from certain height.
