ASTM D2843: Standard Test Method for Density of Smoke from the Burning or Decomposition of Plastics

This fire test response test method covers a laboratory procedure for 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. 

Applicable products: Plastic material 

Testing procedure: During the 4-minute testing period, test samples are exposed to flame, and the resulting smoke is primarily contained within the test chamber. The transverse light absorption was measured through the beam path of a photodiode, and the condition of the smoke chamber was observed. 

Test results: There are two indicators used to evaluate the materials: maximum smoke generated and smoke density rating.

Instrument structure:

Divided into two main parts: 1, the smoke chamber and  2, the control section;Smoke chamber section: On the left and right side panels of the smoke chamber, there are the power switch, safety symbol switch (backlight switch), gas adjustment device, and also the switch for controlling the exhaust fan (fan switch).
