Regulatory Tests To Be Carried Out On The Equipment According To Standard - Sames inocoat Inogun A Instruction Manual

14 Inside the booth it is forbidden to use naked flames, glowing objects or devices likely to produce sparks.
It is also forbidden to store flammable products, or recipients that have contained them, in the vicinity of the
booth. The surrounding area must be kept clear and clean.
15In the explosive zone, it is forbidden to use non-certified electrical or non-electrical equipment such as
electrical extension cords, multi-sockets, switches, etc.
A warning sign in a language understood by the operator, summarising the safety rules described above, must be
prominently displayed in the vicinity of the powder spray station.
1.6. Regulatory tests to be carried out on the equipment according to standard EN 50177
The tests must be carried out on the spraying equipment. The tests must be carried out by competent personnel
and include the tests described below (see § 6.2 table 3 in standard EN 50177).
Type of test
The fixed inflammable coating powder
material electrostatic coating must be
tested to ensure it is safe for workers.
Forced ventilation effectiveness
(air extraction systems)
The safe high voltage disconnection
must be tested for operation under
controlled voltage and under constant
voltage.
3D category devices
2D category devices
In this context, and particularly for the disconnection threshold, the overload
current Iü and the minimum voltage Umin must be defined and documented in
relation to the operational and local conditions (see also § 5.2.2 in standard
EN50177).
See §5.4.4 in standard EN50177
See 5.2.2 and 5.2.2.1 in standard EN50177.
The disconnection threshold Iü must be defined and documented in relation to the
operational and local conditions.
It must be tested if the high voltage is disconnected and if there is an
unacceptable increase in the operating current Ib and if the disconnection
threshold Iü is reached. In this context, the disconnection threshold Iü defined
during the initial test must be checked.
A disconnection threshold Iü that may increase the possibility of dangerous
discharges or electrical flashovers between the parts under high voltage and the
grounded parts if the safe distance falls below its permitted value is not permitted.
