Overview

EN ISO 28927-3:2009 specifies standardized laboratory test methods for evaluating hand-transmitted vibration emission at the handles of hand-held, power-driven portable polishers, and rotary, orbital, and random orbital sanders. Developed by the European Committee for Standardization (CEN), this standard aims to provide reliable and reproducible methods for measuring vibration magnitudes in gripping areas under controlled type-test conditions. The results derived from these tests allow for objective comparison of different models within the same tool category, supporting vibration safety, product selection, and compliance with regulatory requirements.

Key focus: The standard covers surface-finishing tools (not for material removal) powered pneumatically or by other means. It does not apply to straight grinders with sanding wheels or belt sanders.

Key Topics

Scope and Applicability
- Covers hand-held machines such as polishers and sanders used for surface finishing.
- Applicable to tools powered by pneumatic, electric, or other sources.
- Outlines tool and process exclusions, including straight grinders with sanding wheels and belt sanders.
Test Procedures
- Specifies exact test conditions in laboratory environments.
- Measurements are conducted at tool handles where the operator grips.
- Vibration is measured simultaneously in three orthogonal directions at each relevant handle position.
- Prescribes locations for sensors to minimize operator disturbance and ensure accurate results.
Measurement and Reporting
- Defines calculation methods for the vibration total value using root-mean-square values across all measured axes.
- Standardizes reporting formats for vibration test data, supporting both internal and regulatory documentation needs.
- Ensures traceability and repeatability of results through detailed procedures.
Compliance and Safety
- Relates to the requirements of EU Directives 98/37/EC and 2006/42/EC (Machinery Directive) for health and safety.
- Results can be used to demonstrate conformity and support declarations of vibration emission values.

Applications

Tool Manufacturing: Manufacturers use EN ISO 28927-3 to design and qualify portable power tools, ensuring their products meet vibration emission requirements and can be accurately compared to competitor models.
Occupational Health and Safety: Employers and health & safety professionals utilize vibration test data produced by this standard to assess and mitigate workplace vibration exposure risks, supporting compliance with health regulations.
Procurement and Specification: Comparing standardized vibration values allows buyers to select tools with lower vibration emissions, helping to reduce operator fatigue and risk of hand-arm vibration syndrome (HAVS).
Market Access: Adherence to this standard is often necessary for CE marking and market introduction within the European Economic Area.
