GSO ISO 9835:2012 Scope
This International Standard specifies a method for
measuring the black smoke index of an ambient air
Sample. The method is based on the staining effect
of particles which is produced when a Sample of air
is drawn through a filter Paper.
The method is intended for the measurement of a
black smoke index in the range 6 to 375 in the ambient
atmosphere. lt is based on the measurement of
reflectance. The method does not measure the mass
concentration of particles directly.
