Frequently asked questions:-

What is smoke density?

The ratio of the smoke material to the smoke emitted by a emitted by a burning standard material

How is smoke density measured?

Conceptually represents the exponential light the smoke density terms loss length of the smoke column.  Smoke unit in air and smog, by having a beam density sensitive per of light is measured, like fog of known intensity away and measuring how much a given distance light gets through.

What is ASTM D2843?

It is a for D295 Smoke Density Apparatus for Standard Test Method the of Plastics Burning or Decomposition.
