cific elements are listed in Table 1. This test method is similar to Test Method D 5185, but differs in methodology, which results in the greater sensitivity required for insulating oil applications.
1.2 This test method uses oil-soluble metals for calibration and does not purport to quantitatively determine insoluble particulates. Analytical results are particle size dependent, and low results are obtained for particles larger than several micrometers.
1.3 This test method determines the dissol
