3.1.2. Pneumatic characteristics
*: Values are given for a temperature of 20 °C (68 °F) at an atmospheric pressure of 1 013 mbar
3.2. Noise level
3.2.1.
Inobooth
in operation phase
The weighted equivalent continuous sound pressure level is 75.5 dB (A) under the specified ope-
rating conditions
Measuring conditions
: the equipment was put into operation at maximum characteristics, the
measurements were carried out at different positions at 1 m from the powder station and on
the side accessible by the user in the powder laboratory on the
SAMES KREMLIN
site in Mey-
lan, France.
Method of measurement:
The weighted equivalent sound pressure level of 75.5 dB (A) is in LEQ
value, measured over observation periods of at least 30 seconds.
