Today, Haoshun will take you to understand how to test the cleanliness of a dust-free workshop and what the daily cleaning of a dust-free workshop includes.

How to Test Cleanliness of a Dust-Free Workshop

The standard for judging the quality of a clean room is cleanliness, but there is no clear test method for this indicator. Today, Shenzhen Guanhang Environment will introduce you to several simple methods to test the cleanliness of a clean room.

1. Test under empty conditions

It means that the dust-free workshop system is in normal operation, but the process equipment and production personnel have not yet entered the test.

2. Test under dynamic conditions

It means that the dust-free workshop system is in normal operation, and the process equipment and production personnel are all working.

2. Test under static conditions

It means that the dust-free workshop system is in normal operation, the process equipment has been installed but not running, and the test is carried out without any production personnel in the room.

The content introduced above is the test method for cleanliness of clean room. It is worth noting that, in general, the test method for air cleanliness in a clean room should use the light scattering particle counting method for the counting of dust particles with a particle size greater than or equal to 0.5 microns. For dust particles with a particle size greater than or equal to 5 microns, the filter microscope counting method can also be used.
