ASTM D923-97<\/h3>\n

Historical Standard: Standard Practices for Sampling Electrical Insulating Liquids (Withdrawn 2006)<\/h4>\n
\n

ASTM D923<\/h4>\n

Scope<\/strong><\/p>\n

1.1 These practices cover sampling of new electrical insulating liquids including oils, askarels, silicones, and synthetic liquids as well as such liquids in service or subsequent to service in cables, transformers, circuit breakers, and other electrical apparatus. This test method shall apply to liquids having a viscosity of less than 3000 SUS (Saybolt Universal s) (647.3 cSt) and 100\u00b0F (37.8\u00b0C).<\/p>\n

1.2 The values stated in inch-pound units are to be regarded as the standard.<\/p>\n

1.3 Sampling procedures using syringe-type devices, tin plated steel cans with flexible sides and stainless steel cylinders are described in Methods D3613. This method describes preferred techniques to use when sampling for dissolved gas analysis and water content in insulating fluid.<\/p>\n

1.4 The procedures appear in the following order:<\/p>\n

Procedure Section\/Paragraph Dip-Type Device 6.2, 13, and X1.1 Pressure-Type Device 6.3, 14, and X1.2 Tank Car-Type Device 6.4, 15, and X1.3 Manifold-Type Device 6.5, 20, and X1.4 Electric Equipment Sample Outlet 6.6 and 18 <\/p>\n

1.5 Handle askarels as outlined in ANSI C107.1 to avoid environmental contamination. For methods of testing askarels see Methods D901.<\/p>\n

1.6 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 12.7, 14.2, Section 17, 19.2, and 21.2.3.<\/p>\n
