# Before testing, make sure that the air speed and
volume of the filters must be appropriate.
# To access the filters, existing air diffusers and
airflow laminators (whatever can be applied) must be removed.
# HEPA / ULPA
filter is a photometer with an aerosol concentration of 20-80 mg / L and an
aerosol concentration value indicator (e.g. HEPA).ATI TDA, 2H,2G)
# set the Aerosol photometers to 100% and zero and
save the values to the table above the item
# change to the test position (downstream) and scan
the total surface of the filter and the edges that keep the probe approximately
2.5 cm below the surface of the filter with a scan speed of no more than 0,
093m2/min (scan test).
* # If maximum applicable after 5 HEPA/ULPA filter
tests during testing, aerosol concentration, 100% and zero control must be
verified and recorded.
