scope:

This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held saws, polishing and filing machines with reciprocating action and small saws with oscillating or rotating action. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of the tools.
This part of ISO 28927 applies to reciprocating files intended for surface finishing equipped with a file or a polishing tool, saws intended for parting sheets, plaster for medical use or wood, equipped with saw blade for use on all kinds of materials and small circular saws primarily intended for cutting metal or composite materials.
The power tools covered by this part of ISO 28927 may be pneumatically driven, or driven by other means.
Typical tools are illustrated in figure 1-11.
This part of ISO 28927 applies to the tools mentioned in clause 5. It does not apply to files that are normally used with one hand on the file blade. Further it does not apply to big circular saws intended for cutting wood.
It is intended that the results can be used to compare different models of the same type of power tool.
