    ASTM D5256

    Significance and Use

    5.1 This test method is useful because the choice of a solvent system for removing water-formed deposits depends upon the ability of the dynamic solvent system to dissolve both unattached and attached deposits.

    1. Scope

    1.1 This test method covers the determination of the relative efficacy of dynamic solvent systems for dissolving water-formed deposits that have been removed from the underlying material or deposits attached to the underlying material.

    1.2 The nature of this test method is such that statements of precision and bias as determined by round robin tests could mislead users of this test method (see Sections 11 and 12). Therefore, no precision and bias statements are made.

    1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

    1.4 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.
