Verification Standards and Indirect Verification Method of Pendulum Impact Testing Mechine According to European Standard

JJG 145-2007, ASTM E23-2002 and EN 10045-2-1992 three standards for verification of impact testing machines had been introduced. The indirect verification of a pendulum impact testing machine produced by a China factory had been performed according to European standard EN 10045-2-1992, the indirect verification process and the matters of attention were described in detail, and the result of verification was given at last. The result indicated that the repeatability and error of the test machine for the media and low energy absorbed were conformed to the requirement of EN 10045-2-1992, but for the high energy absorbed, the repeatability was not within the requirement of the standard, so the effective range of the verified impact testing machine was 0~110 J.
