    Significance and Use

    5.1 The test method results are suitable for use by manufacturers of colorants and bases for quality control purposes on manufactured product.

    5.2 The test method results are suitable for use by purchasers of colorants and bases for incoming quality control or the determination of money value of colorants and bases.

    1. Scope

    1.1 This test method covers the determination of strength of colorant dispersions, colored and white bases, for architectural, marine, maintenance, commercial, and industrial coatings.

    1.2 This test method applies to colorant dispersions and colored and white bases regardless of the methods used to disperse these materials.

    1.3 The resultant test value is in terms of percent strength in which a material stronger than standard is implied by values larger than 100 % and weaker than standard is implied by values less than 100 %. The value of 100 % implies exact strength conformance to the test method.

    1.4 This test method is suitable for the determination of strength when tolerances are set about standards that are prepared either by weight concentration or volume concentration.

    1.5 The test result is empirically determined. The user determines and supplies the standard for strength of the product under test and the test result is relative to that supplied standard.

    1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

    1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
