Sound and Vibration Specifications

The required sound specification, Paragraph 1.7.4.2.u of 2006/42/EC Machinery
Directive, is:
■ the sound pressure level at operator's location (L
■ the guaranteed sound power level (L
These sound values were determined according to ISO 3744 for the sound power
level (L
location.
ISO 5349 Part 1 Annex F states, "The vibration characteristics of a vibrating tool
can be highly variable. It is therefo2re important that the range of vibration
conditions associated with different work pieces, materials, working conditions,
methods of use of the tool, and exposure duration patterns be reported."
■ The average hand and arm vibration value obtained for the entire operating
■ The maximum hand and arm vibration value obtained within the entire
■ The minimum hand and arm vibration value obtained within the entire
Products are tested for hand/arm vibration (HAV) level in accordance with ISO
5349 Part 1 and ISO 8662 Part 1.
