MEASUREMENT OF THE OPACITY OF DIESEL SMOKE
MESSUNG DER OPAZITAET VON DIESELRAUCH
In EEC regulation no. 24, visual disturbance by diesel smoke was established as a determinative value of nuisance caused by diesel exhaust fumes. On the basis of this, the revised requirements for measuring procedure and measuring equipment led to a basic examination of the measuring procedure at the Battelle Institute and the development of equipment by the firm Robert Bosch Gmbh. The measuring principle is based on the determination of the extinction of visible light during the passing through of a defined area. An assigned comparative measuring area enables measurement of the difference to be undertaken, which represents a direct measure of the absorption coefficients of the test medium given standardization and evaluation of signals. The structure, method of operation and possible applications of the equipment are described. The covering abstract for the conference is IRRD no. 208556. /TRRL/
