1.1 This test method covers the determination of the gas content of electrical insulating oils of low and medium viscosities in the general range up to 190 mm 2 /s at 104°F [40°C], such as are used in capacitors and paper-insulated electric cables and cable systems of the oil-filled type. The determination of gas content is desirable for any insulating oil having these properties and intended for use in a degassed state.
N OTE 1—For testing insulating oils with viscosities of 19 mm 2 /s or below at 40°C, see Test Method D2945.
