DIN EN ISO 28927-4:2011 PDF

Scope: This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of straight grinders. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with a specified test wheel and run under no-load conditions. This part of ISO 28927 is applicable to hand-held machines, driven pneumatically or by other means, intended for grinding and surface finishing using straight grinding wheels type 1, tapered wheels type 4 and cylindrical plugs, e.g. of type 16 (cylindrical plug, tapered cone), 18 (cylindrical plug, flat end), 18R (cylindrical plug, rounded end) and 19 (cylindrical plug, taper-roll shaped), for use on all kinds of materials. It is not applicable to grinders used with wire brushes, nor is it applicable to die grinders where the inserted tool is mounted in a collet.
