|Publication Date:||1 October 2015|
|ICS Code (Insulating oils):||29.040.10|
This test method describes testing of new electrical insulating liquids as well as liquids in service or subsequent to service in cables, transformers, oil circuit breakers, and other electrical apparatus.
This test method provides a procedure for making referee tests at a commercial frequency of between 45 and 65 Hz.
Where it is desired to make routine determinations requiring less accuracy, certain modifications to this test method are permitted as described in Sections 16 to 24.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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 to determine the applicability of regulatory limitations prior to use. Specific warnings are given in 11.3.3.
Mercury has been designated by the EPA and many state
agencies as a hazardous material that can cause nervous system,
kidney and liver damage. Mercury, or its vapor, may be hazardous to
health and corrosive to materials. Caution should be taken when
handling mercury and mercury containing products. See the
applicable product Material Safety Data Sheet (MSDS) for details
