Popis

BS 1747-11:1993


This standard BS 1747-11:1993 Methods for measurement of air pollution is classified in these ICS categories:
  • 13.040.20 Ambient atmospheres

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. It is based on the measurement of reflectance. The method does not measure the mass concentration of particles directly.


Gives a reflectance method for continuous or daily measurement of the black smoke index in the range 6 to 375.
