IEC 60745-2-12 Hand-held motor-operated electric tools -Safety -Part 2-12: Particular requirements for concrete vibrators

Scope

This clause of Part 1 is applicable, except as follows:

Addition: This standard applies to concrete vibrators.

Normative references

This clause of Part 1 is applicable.

Terms and definitions

This clause of Part 1 is applicable, except as follows:

Replacement:

normal load: load obtained when the tool is operated continuously, the hose and vibrator bottle being attached to the tool as for normal use. During the operation the vibrator bottle is immersed centrally in a container filled with an amount of water corresponding to at least 50 times the volume of the vibrator bottle.

The dimensions of the container are such that the diameter is about 50% of the height of the water inside the container.

The height of the container is such that no water can splash out during the test.

Addition

concrete vibrator : tool intended for compacting concrete. The active part (vibrator bottle) of the vibrator performs ow-amplitude vibrations and is immersed into the mass of concrete to be vibrated.

Concrete vibrators may be of one of the following designs:

a) the motor and the vibrating mechanism are inside the vibrator bottle to which the part containing the mains switch or a power converter and switch handle assembly is connected by means of a long flexible hose containing the interconnecting cable. The long flexible hose may be used as the handle (see Figure 101);

b) only the vibrator mechanism is inside the vibrator bottle to which a separate portable unit, comprising the motor, the handle and the mains switch, is connected by means of a long flexible hose containing a flexible shaft(see Figure 102)
