GB/T 16581-1996
ActiveTest method for the determination of oxygen index of insulating liquids
绝缘液体燃烧性能试验方法 氧指数法
Application Summary AI generated
This standard specifies the oxygen index test method for insulating liquids, determining the minimum concentration of oxygen in a nitrogen-oxygen mixture that will support combustion. It is applied in the electrical engineering industry to evaluate the flammability of transformer oils, capacitor impregnants, and other liquid dielectrics used in high-voltage equipment. The test is critical for assessing fire safety risks in electrical apparatus where insulating liquids are present.
