Describes a small-scale laboratory procedure for determining the comparative burning characteristics of tubular polymeric materials. A flame is applied to test specimens held in a vertical position, supported by a wire or mandrel. Upon removal of the test flame, the extinguishing times and the burning characteristics are determined. This test method can be used to compare the burning characteristics of tubular polymeric materials. This test method shall not be used to compare the burning characteristics of any wire or cable products or any cable management systems. This test method can be used to compare the relative performance of materials, to aid in material selection, for quality control purposes and for quality assurance. Has the status of a basic safety publication in accordance with IEC Guide 104.
