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.
