HAVTEC (Hand-arm Vibration Test Centre) TERMS AND CONDITIONS

The following additional terms and conditions apply in respect of any use of the HAVTEC Register on the OPERC site.

1 Availability of the results
Without limitation to the generality of conditions 5 and 6 of the Terms and Conditions above, test results must not be sold nor distributed to a third party without the prior written permission of OPERC. Neither can information contained in the HAVTEC Register be used in commercial products, services, literature or any other medium that seeks to make a profit or charge, directly or indirectly from such information. Users of the HAVTEC Register are advised to regularly update themselves with 'current' register information since reputable manufacturers are constantly improving the performance of their tools and new tools are tested continually.

2 Interpretation of the results
Generic and specific issues need to be considered when interpreting these results. There are always constraints when performing vibration measurements and these apply here. That is:

  • The measurements taken in these trials only used one sample of the tool. It is possible that the tool used is not entirely representative of other tools of the same model, due for example, to manufacturing tolerances.
  • Differences between these measurements and repeat measurements could occur, due to environmental conditions such as ambient temperature and supply frequency or voltage.
  • Only three participants were used for these trials. Some inter-operator differences were observed. Further and more extreme variations could be likely among other operators. Such differences could be due to individual anthropometry, biomechanics or tool operation style.
  • The tool tested was new and had an inserted tool in good condition. The performances of any power tool degrades as the inserted tool becomes dull. The performance of the tool tested here is likely to change as the tool ages.
  • Trials were performed on materials as dictated by manufacturers' budgets; those with higher budgets have completed more testing. However, vibration magnitude is affected by the nature of the material work piece. Ideally more trials would be completed using different work pieces such that an indication of variation could be obtained.

3 Guidance on tool purchasing decisions
Vibration data should only be used as one criteria upon which any purchasing decision should be made. Other considerations include: durability and reliability of the tool; service support and guarantees given; ease of maintenance; performance; longevity; and cost. Users should consider that as a tool ages, rotating and reciprocating parts wear and thus vibration levels increase and some tools may 'initially' have a lower vibration reading when new but may experience higher values (than competitor tools) during the machine's life.

4 Use of data
The data presented in the HAVTEC Register is not provided as a solution to preventing operator over-exposure to excessive vibration levels. Rather it provides guidance information that will be useful to practitioners when used in conjunction with other control measures, for example: health surveillance; risk assessments; job rotations; maintenance of the tools; correct usage of personal protective equipment; and the correct selection of tools for the given task undertaken.

5 Legal obligations
The HAVTEC register does not replace any legal obligations upon employers (or employees) to provide (or undertake) basic health and safety training (or any other mandatory requirements, for example, under relevant health and safety legislation).

Every test undertaken and recorded on the HAVTEC Register provides a unique set of vibration hazards and similarly, every person is unique in terms of cognitive and physical ability, knowledge and so on. For reasons such as these, the HAVTEC Register must be accepted by the user solely as providing a basis for educational materials and nothing more.

Every effort has been made to ensure that the contents of the HAVTEC Register are correct, and representing best practice; but no guarantee is made express or implied that this is the case. It is also the user's responsibility to ensure that this version of HAVTEC is current. Accordingly the HAVTEC Register is offered without legal liability or responsibility on the part of the authors, the publishers, the distributor or anyone else involved in its production.

We provide information on the HAVTEC Register free of any access charge and on the basis of no liability for the information given.

In no event shall we be liable to you for any direct or indirect or consequential loss, loss of profit, revenue or goodwill arising from your use of the HAVTEC Register or information on HAVTEC Register. All implied terms are excluded to the fullest extent permitted by law.

We accept liability only for death or personal injury caused by our negligence or responsibility for fraudulent misrepresentation that cannot, under English law, be excluded.

6 Manufacturer's consent to publish
Information contained within the HAVTEC Register will only be reproduced with the manufacturer's consent and approval, made in writing, to OPERC to OPERC Administration, PO Box 5039, Dudley, West Midlands, DY1 9FQ.

7 Ownership
Data contained within the HAVTEC Register will not be reproduced nor disseminated by users, in any format, without the permission of OPERC. Any usage of the data must include a statement in the following form or such other form as we may require from time to time.

"This information on vibration readings for plant and equipment was supplied free of charge by OPERC (www.operc.com)."

Text size must be minimum 8pt. font and should be accompanied by the OPERC logo (no smaller than 20mm x 20mm); copies of the logo can be supplied free of charge upon request to enquiries@operc.com.

8 Test badge scheme
Manufacturers and hirers who supply tools and equipment to be tested at OPERC, or those who support this initiative, may be granted the right to use the official OPERC badge on their products to advertise to users that such have been independently tested at OPERC.
