scope:

Specifies a laboratory method of measuring the vibration at the handles of wrenches, screwdrivers and nutrunners with impact, impulse, rapping or ratcheting action. It is a type test procedure for establishing the vibration value at the handles of the power tools when operating on the specified load. The standard mainly covers power tools with 6,3 mm to 40 mm, which corresponds to 1/4" to 1 1/1", male of female square drive output shafts;other drive geometries are also included. One-shot tools are excluded from this standard. The power tools covered by this part of ISO 8662 may be pneumatically of hydraulically driven. It is intended that the results can be used to compare different power tools or different models of the power tool. With the operation specified for the power tools the values obtained will give an indication of those found in real work situations when the power tool and the head of the fastener are well aligned.
