Noise emission levels determined by using ISO/CD 15744
Levels of vibrations at the handle determined by using ISO 8662
Note:
make sure that the performance features required correspond to those described above, otherwise it will be
necessary to choose a different model from the broad range offered by OBER.
TOOL NOISE
The table of technical specifications indicates the noise level- where the noise level exceeds 85 dB (A) the noise power is
also indicated. Ear protectors must be worn where the noise level exceeds 85 dB (A) at the operator position. We
recommend that you also wear ear protectors below this noise level.
Noise risk and hearing damage are related to the intensity of the noise source and the length of exposure. Noise risk
must be assessed on a case by case basis taking into account these two factors. Measures should be taken to protect
the user against hearing damage in accordance with current Health and Safety regulations.
The formula and table can be used to calculate the daily exposure level for a tool using the use coefficient c. The use
coefficient
c
for a tapping head is between 20 and 40%.

TOOL VIBRATION
The tool in question, tested with regard to the conditions required by the relevant technical standards for feed pressure:
•
ISO 2787 (Rotary and percussive pneumatic tools - performance tests)
for general test indications:
•
ISO 5349 (Mechanical vibration - Guidelines for the measurements and the assessments of human exposure to hand-transmitted vibration
for weighting factors:
•
ISO 5349 (Mechanical vibration - Guidelines for the measurements and the assessments of human exposure to hand-transmitted vibration
characterised by the following level of vibrations:
a
h
= frequency-weighted acceleration <2.5m/s
2
The risk from vibrations is linked not only to the intensity of the source, but also to the exposure time and it is therefore
advisable to evaluate the use of the individual tool during the working day and stick to the regulations in force in individual
countries in order to protect users.
