Hand-held portable power tools - Test methods for evaluation of vibration emission - Part 9: Scaling hammers and needle scalers (ISO 28927-9:2009)

ISO 28927-9:2009 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven scaling hammers and needle scalers. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine run under specified test conditions. It is intended that the results be used to compare different models of the same type of machine.
ISO 28927-9:2009 is applicable to engraving pens, scabblers, scaling hammers and needle scalers, driven pneumatically or by other means, intended for paint, rust or scale removal with reciprocating work tools or needles and for all kinds of materials.

Overview

EN ISO 28927-9:2009 - Hand-held portable power tools - Test methods for evaluation of vibration emission - Part 9: Scaling hammers and needle scalers (ISO 28927-9:2009) specifies a laboratory, type-test method for measuring hand-transmitted vibration emission at the handles of scaling hammers, needle scalers, engraving pens and scabblers. The standard defines how to establish the magnitude of vibration at gripping areas under specified test conditions so results can be used to compare different models and support machine conformity assessments.

Keywords: ISO 28927-9:2009, vibration emission, hand-held power tools, scaling hammers, needle scalers, hand-transmitted vibration, test methods.

Key Topics

• Scope and applicability: Applies to pneumatic or other driven tools intended for paint, rust or scale removal with reciprocating work tools or needles, and to engraving pens and scabblers.
• Measurement strategy: Laboratory type-test procedure to characterise vibration at the user’s hand positions; includes measurement in multiple axes and at both hand positions where relevant.
• Instrumentation requirements: Specifies transducers, mounting and fastening methods, frequency-weighting filters, integration time, calibration and auxiliary equipment needed for valid measurements.
• Test conditions and setup:
  • Defined operating conditions for pneumatic, hydraulic and electrical machines.
  • Specified test fixtures, workpiece (e.g., mild steel plate or concrete block) and feed-force guidance.
  • Operator roles and repeatability considerations.
• Data reporting and verification: Procedures for calculating reported vibration values, combining directional components, uncertainty determination and preparing a measurement report suitable for declaration and verification.
• Regulatory linkage: Informative annexes relate the standard to EU Machinery Directives (e.g., 2006/42/EC), providing a presumption of conformity with certain essential requirements within the standard’s scope.

Applications

Who uses EN ISO 28927-9:2009 and why:

• Tool manufacturers - to verify and declare vibration emission values during product development and type-testing, enabling model comparison and design optimization for reduced hand-transmitted vibration.
• Test laboratories - to perform standardized, repeatable laboratory measurements for independent evaluation and certification.
• Occupational health & safety professionals - to assess comparative vibration risks and inform tool-selection, exposure assessment and control measures.
• Regulatory and compliance teams - to support conformity assessment with relevant EU directives and national standards.

Practical benefits: comparable vibration emission data across models, improved user safety through better-informed tool selection, and consistent test methodology for procurement and certification.

The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 28927-9 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools, machines and equipment, Subcommittee SC 3, Pneumatic tools and machines. This first edition of ISO 29827-9, together with ISO 29827-11, cancels and replaces ISO 8662-14:1996, of which it constitutes a technical revision. The most important changes are ⎯ vibration measurement in three axes and at both hand positions, ⎯ new transducer positions, ⎯ stone working tools become stone hammers and the subject of a separate Part 11, and ⎯ reference to energy absorbers deleted and all tools now tested on a mild steel plate or concrete block.

ISO 28927-9:2009(E) vi © ISO 2009 – All rights reserved Introduction This document is a type-C standard as stated in ISO 12100. When requirements of this type-C standard are different from those which are stated in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. The vibration test codes for portable hand-held machines given in ISO 28927 are based on ISO 20643, which gives general specifications for the measurement of the vibration emission of hand-held and hand-guided machinery. ISO 28927 specifies the operation of the machines under type-test conditions and other requirements for the performance of type tests. The structure/numbering of its clauses follows that of ISO 20643. The basic principle for transducer positioning first introduced in the EN 60745 series of European standards is followed, representing a deviation from ISO 20643 for reasons of consistency. The transducers are primarily positioned next to the hand in the area between the thumb and the index finger, where they give the least disturbance to the operator gripping the machine. It has been found that vibrations generated by scaling hammers and needle scalers vary considerably in typical use. The percussive action is the prime source of vibration, and the variation is largely due to variations in the handling of the machine and the characteristics of the material being worked on. Differences in the support of the material also cause differences in vibration. This part of ISO 28927 uses a working process where the machine is used to work on a steel or concrete surface. In order to achieve good reproducibility, it is important that the material have good support and that the inserted tools used be in good condition. The procedures of ISO 5349 are required whenever exposure at the workplace is to be assessed. The values obtained are type-test values intended to be representative of the average of the upper quartile of typical vibration magnitudes in real-world use of the machines. However, the actual magnitudes will vary considerably from time to time and depend on many factors, including the operator, the task and the inserted tool or consumable. The state of maintenance of the machine itself might also be of importance. Under real working conditions, the influences of the operator and process can be particularly important at low magnitudes. It is therefore not recommended that emission values below 2,5 m/s2 be used for estimating the vibration magnitude under real working conditions. In such cases, 2,5 m/s2 is the recommended vibration magnitude for estimating the machine vibration. If accurate values for a specific work place are required, then measurements (according to ISO 5349) in that work situation could be necessary. Vibration values measured in real working conditions can be either higher or lower than the values obtained using this part of ISO 28927. The vibration test codes given in ISO 28927 supersede those given in ISO 8662, whose parts have been replaced by the corresponding parts of ISO 28927 (see Foreword). NOTE ISO 8662-11, Hand-held portable power tools — Measurement of vibrations at the handle — Part 11: Fastener driving tools, and ISO 8662-13, Hand-held portable power tools — Measurement of vibrations at the handle — Part 13: Die grinders, could be replaced by future parts of ISO 28927.
