NBS Smoke Density Chamber.pdf

What is a NBS smoke chamber?

The NBS smoke density chamber (ASTM E662) is the most popular test instrument used to measure smoke obscuration. In its standard use, it can accommodate only samples in the vertical orientation.

What is a smoke chamber used for?

The smoke chamber is the area above the fireplace firebox (where you build your fire) just below the flue. This space is used to allow smoke to mix and curl in a circular motion and rise into the flue.
