Needle-flame test

This method is used to test and assess the fire hazard presented by a plastic material using a needle flame.

It determines the impact of a small flame on the test specimen. In particular, it calculates the severity, in other words the exposure time to the flame after which the material will just about meet the specified requirements

Summary of the test method:
The test specimen is arranged in a vertical position over tissue paper. A propane gas flame is applied to the edge and the flat surface. The burning time, burning behaviour and severity (exposure time) are determined for this flame applications. The test is usually performed on parts or selected areas of these parts.
