ABSTRACT:
An apparatus and method for determining the propensity of a polymer to emit smoke by measuring the smoke emitted when the polymer is melted and extruded. The polymer is heated to a molten state and extruded under controlled time conditions into a receptacle from which gaseous samples can be collected, then the gaseous samples from the receptacle are analyzed for smoke content to determine the propensity of the polymer to emit smoke.
