Hand-held portable power tools. Test methods for evaluation of vibration emission. Saws, polishing and filing machines with reciprocating action and saws with oscillating or rotating action | Status: Under review, Current

1 Scope This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven 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 a machine run under specified test conditions. It is intended that the results be used to compare different models of the same type of machine. This part of ISO 28927 is applicable to reciprocating files intended for surface finishing equipped with a file or polishing tool, saws intended for parting sheets, plaster for medical use or wood, or equipped with a saw blade for use on all kinds of materials, and small circular saws primarily intended for cutting metal or composite materials (see Clause 5), whether driven pneumatically or by other means. It is not applicable to files that are normally used with one hand on the file blade, nor to large circular saws intended for cutting wood.

NOTE To avoid confusion with the terms “power tool” and “inserted tool”, machine is used for the former throughout this document.
