    ASTM D4350

    Significance and Use

    4.1 This test method provides a means for comparing the corrosive potential of plastics and fillers in humid atmospheres.

    4.2 This test method is intended for use in research and evaluation.

    1. Scope

    1.1 This test method is designed for use in obtaining the specific conductance of a water extract of plastics and fillers. The magnitude of this conductance may be taken as an index of the likelihood that, in a humid atmosphere, metal surfaces in contact with these materials may become corroded due to galvanic action or direct chemical attack; this is called the corrosivity index.

    Note 1There is no known ISO equivalent to this standard.

    1.2 The values stated in SI units are to be regarded as standard.

    1.3 This standard does not purport to address all of the safety concerns, 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 Section 7.
