Hand-held portable power tools - Test methods for evaluation of vibration emission - Part 1 : angle and vertical grinders

This document specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power-driven angle and vertical 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. The method has been established for surface grinding tasks only. Cutting and sanding generally create lower vibrations. It is intended that the results be used to compare different models of the same type of machine.This document is applicable to hand-held machines (see Clause 5), driven pneumatically or by other means, intended for grinding, cutting-off and rough sanding, with bonded, coated and super-abrasive products and with wire brushes for use on all kinds of materials. It is not applicable to die grinders or straight grinders.NOTE To avoid confusion with the terms "power tool" and "inserted tool", machine is used for the former throughout this document.

Hand-held portable power tools - Test method for evaluation of vibration emission - Part 1 : angle and vertical grinders

ISO 28927-1:2009 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power-driven angle and vertical 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. The method has been established for surface grinding tasks only (cutting and sanding generally create lower vibrations). It is intended that the results be used to compare different models of the same type of machine. ISO 28927-1:2009 is applicable to hand-held machines, driven pneumatically or by other means, intended for grinding, cutting-off and rough sanding, with bonded, coated and super-abrasive products for use on all kinds of materials. It is not applicable to grinders used with wire brushes or to die or straight grinders.

Hand-held portable power tools - Test method for evaluation of vibration emission - Part 1: Angle and vertical grinders - AMENDMENT 1 : Cupped wire brushes

Le présent amendement est destiné à élargir le domaine d'application de la norme pour ajouter les brosses métalliques creuses. Il propose également d'ajouter à l'Annexe C une alternative pour les trous des balourds des meules artificielles à moyeu déporté de type 27, comme cela existe dans la NF EN ISO 28927-4 "Machines à moteur portatives - Méthodes d'essai pour l'évaluation de l'émission de vibrations - Partie 4 : Meuleuses droites".

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
