This International Standard describes a procedure for measuring the performance of general ventilation
air cleaning devices in their end use installed configuration. The performance measurements include
removal efficiency by particle size and the resistance to airflow. The procedures for test include the
definition and reporting of the system airflow.
The procedure describes a method of counting ambient air particles of 0,3 µm to 5,0 µm upstream and
downstream of the in-place air cleaner(s) in a functioning air handling system. The procedure describes
the reduction of particle counter data to calculate removal efficiency by particle size.
Since filter installations vary dramatically in design and shape, a protocol for evaluating the suitability
of a site for filter evaluation and for system evaluation is included. When the evaluated site conditions
meet the minimum criteria established for system evaluation, the performance evaluation of the system
can also be performed according to this procedure.
This International Standard also describes performance specifications for the testing equipment and
defines procedures for calculating and reporting the results. This International Standard is not intended
for measuring performance of portable or movable room air cleaners or for evaluation of filter installations
with and expected filtration efficiency at or above 99 % or at or below 30 % when measured at 0,4 µm.
