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 […]

1.1 This practice, 3,4 known as the embrittlement-detector method, covers the apparatus and procedure for determining the embrittling or nonembrittling characteristics ofthe water in an operating boiler. The interpretation of the results shall be restricted to the limits set forth in 8.6. N OTE 1—Cracks in a specimen after being subjected to this test indicate

1.1 These test methods cover the test procedures to be applied to whole tall oils or refined tall oils. Previous editions of these test methods have described test procedures that are used to test tall oil fatty acid, rosin, and other tall oil-derived products as well as test crude and refined tall oil. Consequently, these
