    Abstract

    Most aerospace cleaning specifications require particulate analysis as part of the cleanliness verification process. Trichlorotrifluoroethane, CFC-113, is presently the test solvent of choice for cleanliness verification.

    It has been proposed to use water to replace CFC-113 as the test solvent for cleanliness verification; however it has been speculated that the differences in the physical properties between the two fluids will result in significantly different results in the particle analysis.

    A comparison of deionized water versus CFC-113 has been conducted for several types of sampling of components. This paper presents a description of the tests, the test results, observations, and conclusions regarding the subject.
