This chart compares our exclusive Gelfôm composite material to other materials currently sold as anti-vibration material. Vibration reducing Decade brand gloves with Gelfôm have been tested and certified in Europe to meet strict standards set there for worker protection. Our full-finger gloves are all CE-marked as meeting the European AV glove standard EN ISO 10819. Testing was conducted at Delta Acoustics & Vibration in Denmark. Certification: CD DK-0200-C352.
Hand-Arm Vibration Syndrome (HAVS) affects millions of workers worldwide who use electric, gas and pneumatic power tools or stationary tools that transmit vibration through something the worker must hold. Long-haul drivers, heavy equipment operators or persons driving various utility vehicles also risk developing these disorders.
These workers are found in virtually every industrial classification but especially in manufacturing, mining and construction. As the use of vibrating equipment has increased in recent years, so has the incidence of various HAVS disorders. Vibration exposure can result in circulatory and nerve damage that is painful and long lasting. The development of HAVS may be gradual or a person may begin to feel tingling or numbness of the fingers within a few weeks.
For most HAVS disorders, there is no medical cure. It is obvious, therefore, that protecting workers and removing hazards is critical.
Use of gloves to protect from vibration would seem to be an obvious solution. However, a simple fabric or leather glove has been woefully inadequate over the years. When sponge or foam materials were incorporated in gloves, they proved to be inefficient at damping vibration. Viscoelastic materials perform better but are still shown to be relatively inefficient in testing--in some cases even amplifying vibration through human resonance.
Believing that a material could be developed to meet any testing standard applied to vibration reduction materials - including Europe's EN ISO 10819 - Chase Ergonomics, Inc. worked for more than two years with researchers in the United States and Scandinavia to develop what has become Gelfôm. This new multi-part vibration-reducing pad was tested extensively in an independent European testing lab enabling it to be EC-certified for its unique ability to reduce harmful vibration frequencies to levels specified in the ISO standard.
This certification requires that a material contained in a glove, which is to be labelled an "anti-vibration glove", must reduce vibration in the middle (31.5-200 Hz) and high frequency (200-1250 Hz) ranges produced by many power tools. The EN ISO 10819 standard details the testing methods to be used ad the results that must be achieved by a glove claiming anti-vibration properties.
Among the specified conditions in the standards are the gripping force, feed force, room temperature, humidity, conditioning of gloves, fitting of gloves, test period, posture of the test subject and vibration signals being measured.

I'm sure you'll agree that it has to be worth investing a bit more for standards approved products, what price do you put on your health long term?
