How We Vibration Test Tools

You're in Safe HandsWe use a tried and testing 7 step process to ensure your tools are HAV tested to the highest standards.

1. Enquiry

The first step is for you to make an initial enquiry with us:

2. Consultation

During the initial consultation we may ask you the following questions to help us understand your business:

  • What types of tools are being used?
  • Are you employees currently suffering from any HAV related symptoms?
  • What processes are the tools being used for?
  • Are the tools serviced regularly?
  • Have the tools been HAV tested before?

3. Obtaining a Tool Inventory

Information contained within a tool inventory or asset list will help us identify the tools that may require servicing and repair. For an asset list to be effective, it should contain the following information:

  • Make of the tool
  • Model or part number of the tool
  • Tool I.D number
  • Previous HAV data

4. Hand Arm Vibration Testing

All hand-arm vibration measurements are taken in accordance with BS EN ISO 5349 (2001) Mechanical vibration – Measurement and assessment of human exposure to hand-transmitted vibration.

The exposure to hand-transmitted vibration is quantified in terms of the acceleration of the surface in contact with the hand. The acceleration of the surface is expressed in root mean squared (R.M.S.) meters per second (m/s²).


asessment, HAV testing,

The first stage of our HAV testing process is to insure the tools being tested are safe to use and are in a working order. If there are any issues e.g The tool is unsafe, no test will be carried out.


HAV Testing

The second stage of our HAV testing process involves mounting the accelerometer as close to the trigger as possible in some cases two or three tests must be carried out to determine the highest vibration figure.


HAV Testing

The third stage of our HAV testing process is to test the Tool by replicating how the tool would be used on site for any given application as best as we can.


HAV testing results

The fourth stage is the last in our HAV testing process once the test is completed, our HAV technician calculates the vibration magnitude emitted from the tool. This Information is then written onto a durable tag and attached to the tool.

5. Test Results

Once the tool has been tested, we then record the readings. Based on this information we are then able to work out how long that particular tool can be used for and if monitoring is required and any actions that should taken.

6. Tool Tagging and Certification

The last stage in our testing process is to tag each tool if required and provide a certificate. Where multiple tools have been HAV tested, we are also able to provide written reports at an additional cost. These reports outline our extensive measurement protocol, testing findings and key recommendations to help reduce risk of HAV in your workplace.

Our Tagging System

The vibration level of a particular tool will determine which colour tag it is given. We use the traffic light system to easily differentiate between low risk tools and high risk tools as can be seen from our Hand Arm Vibration Safety Chart below.

7.  Dispatch and Delivery

Once your tool(s) have been fully tested and certified, they will then be sent back to you via your preferred delivery method.

Local customers are able to collect from store.
