Quantity and velocity checks evaluate the quantity and velocity of air circulation. These tests make sure the air inside the cleanroom is exchanged at the desired amount and that the airflow is uniform.
Some classes usually do not involve testing some particle sizes, since the concentration is simply too very low or far too large being realistic to check for, but these blanks shouldn't be examine as zero.
e Sample collection constraints for the two particles in lower concentrations and sizes greater than 1 μm make classification at this particle size inappropriate on account of prospective particle losses within the sampling process.
