ASTM D831/D831M-12(2020)

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 mm²/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.
