Standard Test ASTM G175

Standard Test Method for Evaluating the Ignition Sensitivity and Fault Tolerance of Oxygen Pressure Regulators Used for Medical and Emergency Applications
This test method comprises two phases and is used to evaluate the ignition sensitivity and fault tolerance of oxygen pressure regulators used for medical and emergency applications. Phase 1: Oxygen Pressure Shock Test determines whether the heat or temperature from oxygen pressure shocks will result in burnout or visible heat damage to the internal parts of the pressure regulator. Phase 2: Promoted Ignition Test determines if an ignition event upstream of the pressure regulator inlet filter will result in sustained combustion and burnout of the pressure regulator. This standard provides an evaluation tool for determining the ignition sensitivity and fault tolerance of oxygen pressure regulators and VIPRs used for medical and emergency applications…Learn more
