Abstract： In order to achieve measuring the particle size distribution， particle concentration and mass concentration of smoke simultaneously， the acceptable test of standard-device for smoke concentration was developed. The measurement combined the laser forward scattering theory and extinction theory. Using the test data， the mean values of smoke particle concentration and mass concentration at a certain time were calculated. The results showed that the acceptable test of standard-device for smoke concentration was natural. The values of particle size and particle size distribution of smoke were exact.
