relative assessment of byproduct formation, therefore, can be used as an indicator of the aging of the mineral oil.
1. Scope
1.1 This test method characterizes by spectrophotometry the relative level of dissolved decay products in mineral insulating oils of petroleum origin. While new oil is almost transparent to a monochromatic beam of light in the visible spectrum, the increasing concentration of dissolved decay products shift the absorbance curve to longer wavelengths.
1.2 This test method i
