Test Preparation and Preheating<\/h3>\n<ul>\n<li>Specimen Preparation: Cut the material into standard dimensions (typically 100mm X 6mm X 3mm for rigid bars) and condition them under specified temperature and humidity.<\/li>\n<li>Equipment Stabilization: Turn on the high-temperature oxygen index flammabilitytester. Set the target preheating temperature and wait until both the incoming gasmixture and the inner chimney wall stabilize within +3\u00b0C.<\/li>\n<\/ul>\n<h3>2. Specimen Mounting and Purging<\/h3>\n<ul>\n<li>Mounting: Clamp the specimen vertically at the center of the quartz glass combustionchimney.<\/li>\n<li>Purging: Purge the system with the preheated oxygen\/nitrogen mixture (Method A) orpreheated air (Method B) at a specified standard volumetric flow rate.<\/li>\n<\/ul>\n<h3>3. Ignition and Observation<\/h3>\n<ul>\n<li>Ignition: Apply the standard propane igniter flame to the top face of the specimen for 10to 30 seconds. Remove the igniter once the entire top surface is burning uniformly.<\/li>\n<li>Timing: Start the timer immediately upon flame removal.<\/li>\n<li>Assessment Criteria: Observe the burning behavior of the specimen. It is considered a&#8221;Period of Burning&#8221; (Failure) if:\n<ul>\n<li>The duration of burning exceeds 180 seconds, OR<\/li>\n<li>The flame propagates down past the 50 mm reference mark.<\/li>\n<li>Otherwise, it is recorded as a &#8220;Non-Burning&#8221; (Success) outcome.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>4.
