BS EN ISO 28927-12:2012

This standard BS EN ISO 28927-12:2012 Hand-held portable power tools. Test methods for evaluation of vibration emission is classified in these ICS categories:

• 25.140.10 Pneumatic tools
• 13.160 Vibration and shock with respect to human beings

This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power driven portable die grinders. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of the machines where operating under type 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 hand-held machines (see Clause 5), driven pneumatically or by other means, equipped with a collet and intended for deburring operations using hard metal burrs or mounted points, on different materials ranging from hard steel to plastics. It is also applicable to low-speed die grinders using flap wheels or cylindrical sleeves.

NOTE 1 It is not applicable to straight grinders equipped with type 1 straight wheels, type 4 tapered wheels or different types of cylindrical plugs. For those machines, ISO 28927-4 is applicable.

NOTE 2 It is not applicable to die grinders used with wire brushes.

NOTE 3 To avoid confusion with the terms "power tool" and "inserted tool", "machine" is used hereinafter for "power tool".
