This part of ISO 8662 specifies a laboratory method for measuring the vibrations at the handles of a hand-held pneumatic polisher or rotary, orbital or random orbital sander. It is a type test procedure for establishing the magnitude of vibrations at the handles of the power tool when operating under a specified load.

Four types of power tools are concerned:

• polisher, with circular polishing pad;
• vertical rotary sander, with circular sanding pad;
• orbital sander, with rectangular, circular (or other) sanding pad;
• random orbital sander (including grinding-type tools fitted with a dual-action orbital hub), with circular sanding pad.

This part of ISO 8662 is not applicable to straight rotary sanders and belt sanders.

It is intended that the results be used to compare different power tools or different models of the same type of power tool. With the operation specified for the power tool, the values obtained will give an indication of those found in real work situations.
