SS-EN-ISO-28927-2 › Hand-held portable power tools - Test method for evaluation of vibration emission - Part 2: Wrenches, nutrunners and screwdrivers (ISO 28927-2:2009)
The following bibliographic material is provided to assist you with your purchasing decision:
This part of ISO 28927 specifies a laboratory method for measuring handtransmitted vibration emission at the handles of handheld powerdriven wrenches, nutrunners and screwdrivers used for tightening and loosening threaded fasteners. It is a typetest procedure for establishing the magnitude of vibration in the gripping areas of a machine when operating at a specified load. The method has been tested for fastening tasks only. 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 handheld machines (see Clause 5), driven pneumatically or by other means, with impact or impulse action, of shutoff, ratchet or stall type, and of all designs straight, pistolgrip, angle or bow handle. It covers machines with 6,3 mm to 40 mm (1/4 in to 11/2 in) male or female drive output shafts, as well as other geometries. It is not applicable to nutrunners designed to be used only in torque reaction arms. NOTE To avoid confusion with the terms power tool and inserted tool, machine is used for the former throughout this document.
