7.5 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
pA
) : "A" dB(A)
■ the guaranteed sound power level (L
WA
) = "B" dB(A)
These sound values were determined according to ISO 3744 for the sound power
level (L
WA
) and ISO 6081 for the sound pressure level (L
pA
) at the operator’s
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
rpm range is "C" m/s2.
■ The maximum hand and arm vibration value obtained within the entire
operating rpm range is “D” m/s2.
■ The minimum hand and arm vibration value obtained within the entire
operating rpm range is “E” m/s2.
Products are tested for hand/arm vibration (HAV) level in accordance with ISO
5349 Part 1 and ISO 8662 Part 1.
The sound and vibration specifications were obtained on wetted and cured
concrete using the most commonly sold machine configurations. Vibration values
will vary depending on throttle position, operating conditions, and handle option.
HAV Uncertainties
Hand-transmitted vibration was measured per ISO 5349-1. This measurement
includes an uncertainty of 1.5 m/s
