Description (Translated English): Standard test method for carbon-type composition of insulating oils of petroleum origin
Sector / Industry: Petrochemical Industry Standard (Recommended)
Classification of Chinese Standard: E34
Classification of International Standard: 75.100
Word Count Estimation: 14,151
Date of Issue: 2003-03-18
Date of Implementation: 2003-05-01
Adopted Standard: ASTM D2140-1997, MOD
Summary: This standard specifies the basic physical constants associated with the calculated mineral insulating oil composition of carbon-based method. This standard applies to an average molecular weight of 200 to 600, aromatic carbon atoms between 0 to 50 carbon type composition of the sample. Carbon type composition can be expressed as: aromatic carbon percentage composition, naphthenic carbon percentage composition, percentage composition of paraffinic carbon. If the sample Sticky constant (VGC) and specific refractive index (r (i)) is known, can be obtained from the association of these components in Figure 1. This method only needs to be determined viscosity, density, relative density, refractive index these data. This standard applies to the determination used in transformers, transmission cables on carbon-based electrical insulating oil composition analysis. Mainly for the increase or add new oil inhibitors. This standard does not purport to this all of the safety concerns, if any, the user has the responsibility before use to establish appropriate safety and health practices and determine the applicable regulatory regime.
