The purpose of the test is to determine the quantity of particles present in the room and to determine the cleanliness grade in accordance with ISO standard 14644-1 The device used for the test is the laser particle counter.

The purpose of the test is to determine whether the HEPA filters are intact and properly installed and to test the sealing joints (appropriateness of housing and other surfaces)

• -photometer, hot particle generator (IES-RP-CC006.2)
• -laser particle counter, cool particle generator (VDI 2083 sheet 3)

The purpose of the test is to determine whether the intake air quantities in the room are sufficient and that the number of air exchanges in the room (according to the useful volume of the room) is in accordance with the requirements.
A device used to the test is the air quantity meter.

The purpose of the test is to determine whether the moisture and temperature are in accordance with the requirements.
Measuring devices used for the test are the moisture and temparature meters.

The purpose of the test is to determine whether the pressure differences among various rooms are in accordance with the requirements.
A device used for the test is the differential pressure meter.

The purpose of the test is to determine whether the speed of air flow under filters or in the working height is in accordance with the requirements (sufficiently high and homogeneous, so that the laminarity of air flow is still guaranteed - where it is required). The speed of air flow can be measured under the filters for the purpose of calculating the number of air exchanges in the room.
A device used for the test is the anemometer filament.

The purpose of the test is to determine whether the direction of air movement in the room is appropriate. In the case of devices with an air curtain the test is performed in order to determine their appropriateness. . The devices used for the test are the smoke generator and a camera or a camcorder..

The purpose of the test is to determine the time required for the room to return to the prescribed cleanliness grade after the artificial generation of particles (especially for rooms with unlaminated air flow) according to standard VDI 2083. Devices used for the test are the laser particle counter and a smoke generator.

The purpose of the test is to determine whether the illumination of the room is within the prescribed values.

The purpose of the test is to determine whether the noise in the room is within the prescribed values.
