  1. Frictional Heating ED36-OWI-035/OCP-800-092 Operating Procedures • These tests determine the ignition characteristics caused by frictional heating in pumps, compressors, and various other oxygen components • The end of a hollow cylinder is rotated against a stationary cylinder on a common axis MAPTIS Presentation

  2. Frictional Heating ASTM-STP-910 Flammability and Sensitivity of Materials in Oxygen Enriched Atmospheres • Typical Specimen • Hollow cylinders 2.5 cm OD and 2.0 cm ID • Ignition Source • Frictional heating • Test Conditions • Max rotation is 30,000 RPM • Max load is 5000 N • Worst-case pressure, temp, and oxygen concentration • Ranking Criteria • The resistance of metals to ignition is measured as the product of the contact pressure and the average linear velocity or Pv product required for ignition MAPTIS Presentation
