ASTM D3455-02

Standard Test Methods for Compatibility of Construction Material with Electrical Insulating Oil of Petroleum Origin (Withdrawn 2011)

SIGNIFICANCE AND USE
The magnitude of the changes in the electrical properties of the insulating oil are of importance in determining the contamination of the oil by the test specimen.
Physical and chemical changes in the oil such as color, interfacial tension and acidity, also indicate solubility or other adverse effects of the test specimen on the oil.
Physical changes of the test specimen such as hardness, swelling, and discoloration show the effect of the oil on the test specimen and are used to determine the suitability of the material for use in insulating oil.
A material meeting the criteria recommended does not necessarily indicate suitability for use in electrical equipment. Other properties must also be considered. Additionally, certain materials containing additives may meet the requirements of these test methods, yet be unsatisfactory when subjected to longer term evaluations. Examples of such materials are polyvinyl chloride (PVC) based compounds, nylon and elastomeric compounds.
SCOPE
1.1 These test methods cover screening for the compatibility of materials of construction with electrical insulating oil for use in electrical equipment.
1.2 This standard does not purport to address all of the safety problems, 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.
WITHDRAWN RATIONALE
These test methods cover screening for the compatibility of materials of constuction with electrical insulating oil for use in electrical equipment.
Formerly under the jurisdiction of Committee D27 on Electrical Insulating Liquids and Gases and the direct responsibility of Subcommittee D27.06 on Chemical Test, this test method was withdrawn in January 2011 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
