Standard Practice for Confirmation of 20-mm (50-W) and 125-mm (500-W) Test Flames for Small-Scale Burning Tests on Plastic Materials

Importancia y uso:

5.1 The flame height and color (indicative of air-to-gas ratio) for a test flame have traditionally been specified in the individual test method. The energy content of the flame has also been addressed by reference to a specific supply gas. It has been determined that the supply-gas back pressure and flow rate can be varied without affecting the height and color of the flame. However, the energy content of the flame is affected. This practice provides the back pressure and flow rate of the supply gas for a 20-mm (50-W) and a 125-mm (500-W) test flame, and a procedure for confirming the heat-evolution profile of the test flame.

5.2 Information is provided for test flames using methane, propane, or butane. Using this information, these supply gases have the capability to be used interchangeably with a standardized burner to produce essentially the same test flame.
