Work Area Air Cleanliness Test (optional)

Air cleanliness is a measurement of all particles (greater than or equal to 0.5 micron in
size) in the air. This is not a standard test. However, if the end user would like to verify
air cleanliness in the work area, follow these instructions:
1. Mark test points at the geometric center of the work surface, and midway
between the center test point and each side wall.
2. Place a particle counter pickup at a height of 16 inches (410 mm) above the work
surface, pointing up into the airflow. Place the particle counter pickup at each of
the three marked test points, and take one sample at each test point of 1.0 ft
air. See Figure 4-29 for reference.
Note: if sampling 1.0 m
passing threshold.
3. Average the particle count results from each of the three test points.
