title: Determination of "vibration emission values" for fastener driving tools (nailers).
abstract: Hand-held fastener driving tools (nailers, staplers, pinners) differ considerably from other vibrating tools in terms of mode of vibration. For satisfying the requirements of the Machinery Directive 89/392/EEC, including also the compulsory declaration of a characteristic vibration value, appropriate measuring methods had to be developed. The measuring method elaborated by the BIA and standardised under ISO 8662-11 takes into account existing regulations and, in particular, specifications applying to the standardised vibration measuring instrument. Apart from aspects related to measuring and working conditions, a particular problem consisted of excluding vibrations which are recorded although not generated by the tool. In addition, the use of vibration measuring instruments according to ISO 8041 was required, too. For these reasons a release cycle time was defined which is both a representative measure for the daily vibration dose and a compromise in terms of measuring accuracy. The paper presents first results obtained on the basis of the standard. It also gives an overview of the state of the art by indicating the load range as a function of the fastener size.
