chemical protective suit or wipe with a sponge.
2. Dry all parts thoroughly inside and outside.
The chemical protective suit can be blow-dried using dry,
oil-free compressed air or in a protective suit dryer system:
– Temperature: maximum 40 °C
– Time: min. 120 minutes
Avoid direct heat radiation or direct sunlight.

To prevent the closure system sticking, protruding
textile threads must be removed.
6.5 Examining tightness of the chemical
protective suit
The test is described for the test device Porta Control 3000.
You can carry out the tests with other test devices, but the
indicated values must be observed.
Carry out the test according to ISO 17491-1, method A.2 at
constant room temperature (20 °C±5 °C).
The compressed air used must comply with the requirements
of EN 12021.
The required test accessories are listed in the order list (see
Chapter 11 on Page 36).
6.5.1 Preparation of test
1. Seal the connections for protective suits with ventilation
unit.
2. Close the fastener system.
3. Spread out the chemical protective suit front-down on a
clean and even surface.
4. Protect the visor with a soft underlay in order to avoid
scratches.
5. Unfasten the protective cap from both suit valves and
remove the valve discs.
6. Fit one test cap on one suit valve and connect it to the test
unit via the blue test hose.
7. Fit another test cap on the other suit valve.
8. Ensure that both valves are connected to the black hose of
the test unit.
9. Connect the test cap to the compressed air supply (6 bar)
via the black hose.

Carrying out the test

CAUTION
!
If the suit is overfilled, the material will be damaged.
When filling the chemical protective suit ensure that
the pressure does not exceed the specified values.
1. Open the blow up valve on the black hose and fill the
chemical protective suit until the test unit shows 17.5 mbar.
Close the blow up valve.
2. Set a settling time of 10 minutes start the stopwatch.
During this time, keep the pressure at approx. 17 mbar so
that a pressure and temperature compensation can be
carried out. If required, top up the air.
3. Open the relief valve. Lower the pressure to 16.5 mbar.
Close the relief valve.
4. Set a test time of 6 minutes and start the stopwatch.
