EN ISO 28927-10:2011 PDF

Overview

EN ISO 28927-10:2011 - “Hand‑held portable power tools - Test methods for evaluation of vibration emission - Part 10: Percussive drills, hammers and breakers” specifies a laboratory type‑test method for measuring hand‑transmitted vibration at the handles of hand‑held percussive machines. It covers portable rock drills, plug‑hole drills, rotary hammers, breakers (pavement/concrete/road breakers), riveting and chipping hammers, pick hammers and similar tools. The standard is applicable to machines driven pneumatically or by other means for drilling or breaking hard materials (rock, concrete, asphalt) and defines the procedure for establishing vibration magnitudes in the gripping areas of a machine fitted with an inserted tool bit.

Key topics and technical requirements

• Measurement scope: Laboratory measurement of hand‑transmitted vibration at the handles of percussive drills, hammers and breakers (type‑test values).
• Applicability / exclusions: Applies to hand‑held percussive tools; not applicable to impact drills with direct mechanical impact mechanisms, jack‑leg and push‑feed rock drills where feed force is not applied by hand.
• Instrumentation & measurement practice: Emphasises three‑axis vibration measurement, transducer mounting near the hand (area between thumb and index finger), frequency weighting filters, integration time, calibration and auxiliary equipment.
• Transducer positions & orientation: Uses transducer locations based on the IEC/EN approach to minimise disturbance to operator grip and to improve consistency.
• Testing conditions: Defines operating conditions, attached equipment/workpiece specification, operator role, and validity criteria for measurements.
• Reporting & conformity: Specifies reported vibration values, declaration and verification procedures, a model test report (Annex A) and uncertainty estimation (Annex B).
• Relationship to legislation: Includes informative Annex ZA describing the link to EU Directive 2006/42/EC (Machinery Directive) for presumption of conformity within the scope.

Applications

EN ISO 28927-10:2011 is used to:

• Generate standardized, repeatable vibration emission data for product datasheets and CE marking claims.
• Support design improvements to reduce hand‑arm vibration (HAV) exposure.
• Provide test results for risk assessments, maintenance planning and occupational safety compliance.
• Compare vibration performance across models or tool families under controlled conditions.

Who should use this standard

• Power tool manufacturers and R&D teams
• Independent test laboratories and certification bodies
• Occupational health & safety professionals and ergonomists
• Procurement specialists and regulatory compliance officers

Related standards

• ISO 28927 series (other parts for grinders, drills, rammers, etc.)
• ISO 20643 (general specifications for vibration measurement of hand‑held machinery)
• IEC/EN standards on transducer positioning (e.g., IEC 60745 series)
