significance And Use:

scope:

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 cSt 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.

1.2 The values stated in inch-pound units are to be regarded as the standard.

Note 1-For testing insulating oils with viscosities of 19 cSt at 40°C or below, see Test Method D2945.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
