Density of smoke from the burning or Decomposition of plastics is measured.
This test method describes the measuring and observing the relative amounts of smoke obscuration produced by the burning or decomposition of plastics.
It is intended to be used for measuring the smoke producing characteristics of plastics under controlled conditions of combustion or decomposition. The measurements are made interns of the loss of light transmission through a collected volume of smoke produced under controlled, standardized conditions.
