Description of ASTM-D901 1997

ASTM D901-91-Reapproved1997

Withdrawn Standard: Standard Test Methods for Askarels (Withdrawn 2004)




ASTM D901

Scope

1.1 These methods cover procedures for testing askarels that are used in transformers and certain other electrical apparatus as an insulating and cooling medium. These methods are generally suitable for specification acceptance, factory control, reference testing, and research. The procedures appear in the following sections:

Test Method ASTM Designation of Test Method
Chemical Tests:
Neutralization Number D664, D974
Water Content D1533
Scavenger Content D1701
Chrlorine Compounds, Hydrolyzable D1820, D2441
Chlorides, Inorganic D1821
Thermal Stability D1936
Electrical Tests:
Dielectric Breakdown Voltage D877
Dissipation Factor and Relative Permittivity D924
Specific Resistance D1169
Physical Tests:
Viscosity D88, D455
Fire Point D92
Pour Point D97
Sampling D923
Refractive Index D1218
Visual Examination D1702
Specific Gravity D1810
Coefficient of Thermal Expansion D1903
Color D2129
Polychlorinated Biphenyls in Environmental Materials D3304
Polychlorinated Biphenyls in Mineral
Insulating Oils by Gas Chromatography D4059

For askarels having a Saybolt Universal viscosity of over 110 s at 100oF, modifications of certain test procedures are necessary.

1.2 As a precaution, insulating systems incorporating askarels and cellulose or other organic materials should be purged to remove any traces of flammable gases by bubbling dry nitrogen through the askarel and flushing the gas space with dry nitrogen before any work is performed on the apparatus.

1.3 Current governmental regulations prohibit the manufacture and sale of polychlorinated biphenyls (PCBs). This method serves as a reference for all askarels, PCB and non-PCB.

Note 1--Various materials have been used successfully in taking, storing, and testing samples of askarels. Until experience has developed a strong preference, materials referred to in these methods will be understood to be approved but not specified.

Note 2--Methods for handling and disposal of askarels and askarel-impregnated materials are given in a recent ANSI Committee C-107 Guide, Guidelines for Handling and Disposal of Capacitor and Transformer-Grade Askarels Containing Polychlorinated Biphenyls.

Note 3--For specifications for askarels, see Specifications D2233 and D2283.

1.4 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. Specific precautionary statements are given in 1.2.
