Revised Standard from Last Update.

1. SCOPE

1.1 This Indian Standard covers the method of testing the performance of immersion type concrete vibrators in terms of limiting values of operational characteristics, like amplitude, frequency, acceleration, range of action, leakage and endurance tests.

1.2 The requirements of this standard apply mostly to flexible shafts driven immersion vibrators powered by different types of motors, as well as electrically driven motor-in-head type vibrators up to 90 mm size. Pneumatic motor-in-head type immersion vibrators and flexible shaft driven or motor-in-head type vibrators of size larger than 90 mm are not covered by this standard although some of the provisions of this standard may also apply to these types of vibrators.
