UpcomingPlastics—Determination of burning behaviour by oxygen index—Part 4: High gas velocity test
塑料 用氧指数法测定燃烧行为 第4部分：高气体流速试验
Application Summary AI generated
This standard specifies a high gas velocity test method for determining the oxygen index of plastics, simulating combustion behavior under forced airflow conditions. It is applied in the rubber and plastics industry to evaluate the flammability of materials used in applications where high ventilation or air movement is present, such as in aerospace, automotive interiors, or electrical enclosures. The test provides critical data for material selection and quality control in contexts requiring enhanced fire safety assessment beyond standard low-velocity oxygen index tests.
