适用范围：1.1 This standard covers the method of testing performance of concrete vibrators immersion type, in terms of limiting values of operational characteristics, like, amplitude, frequency and acceleration, range of action and leakage, and endurance tests.1.2 The requirements of this standard apply mostly to flexible shafts driven and immersion vibrators powered by different types of motors, as well as electrically driver 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.
