8.1

Test rig

The test equipment consists of an inflatable dummy head, a connector leading to the mouth
area, a test rig, a plug to seal the threaded connector. The test equipment, allows for a
negative or positive pressure test.
8.2

Testing

Place the mask to be tested onto the inflatable head (wetting the surface with water) and
tighten the head harness. Inflate until the head becomes stable and in good contact around
the sealing edge of the mask. If necessary, adjust better the head harness. Place the sealing
plug on the inlet threaded connector of the mask. Follow the test equipment instructions as
shown in its instruction manual.
8.3 Mask and exhalation valve leak tightness
The mask and exhalation valve meet the tightness requirements when, after a 10 mbar (1000
Pa) negative pressure is created in the exhalation valve previously damped, the pressure
change is not more than 1 mbar (100 Pa) per minute. If the test is positive, remove the mask
from the rubber dummy head and dry it if necessary. The mask can be used only after passing
the tightness test.

Storage

The masks must be stored in place at a temperature not higher than 50°C, protected from
cold and humidity, the rays of sun, intense heat, corrosive substances which can damage the
rubber, shocks, risk of falling down, dust and dirt. In order to avoid distortion, the rubber
parts must not be submitted to prolonged tensions and pressures. The masks should be
stored in their original packaging, in their carrying bags or in special cupboards.
IDEA masks are classified as special waste according to CER 150203 code and must be
disposed considering that their constituent materials are:
- rubber or silicone,
- plastics,
- metal (small quantities).
Special attention to specific law requirements shall be paid when disposing, depending on
the eventual level of contamination, based on the conditions in which they have been used,
in such case the CER code will be 150202.
10 Specific maintenance instructions and replacement of spare parts
When the mask is disassembled in order to be cleaned and disinfected, it has to be
reassembled following the same procedure of spare parts replacement unless differently
indicated. Make sure that all component parts are correctly assembled, paying attention to
not damage all component parts during these operations.
10.1 Replacement of visor
Loosen the two screws on both sides of the frame Remove the upper part of the frame (pos.3
figure 1) taking care not to damage the central snap and the corresponding tooth on the
screen, then remove the lower part of the frame (pos.4 figure 1) with the same caution and
then remove the visor (pos.2 figure 1) from the groove of the rubber face blank of the mask.
