| Significance and Use | ||||||||||

5.1?This test method is useful for the determination of package and application viscosities of paints and other coatings. It is limited to Newtonian or near-Newtonian liquids. 5.2?This test method may be used similarly to ISO 2431 in conjunction with flashpoint to determine the hazard grouping of viscous liquids in international regulations. |

|
1.1?This test method covers the determination of the flow time (viscosity) of Newtonian and near-Newtonian paints, and related coatings and products using ISO capillary flow cups. Note 1:?If the liquid is non-Newtonian, that is shear-thinning
or thixotropic, Test Methods D2196 should be used.
1.2?The cup-orifice combination (ISO cup with orifice diameter of 3 mm, 4 mm, 5 mm, or 6 mm)1.3?This test method is limited to testing materials for which the breakpoint of the flow from the orifice of the flow cup can be determined with certainty. This point is difficult to determine and reproduce for materials with flow times in excess of 100 s due to slowing-down effects. 1.4?The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. Note 2:?The International Civil Aviation Organization (ICAO)
and the International Maritime Organization (IMO) include in their
regulations a similar test (ISO 2431) to determine the viscosity of
hazardous viscous liquids. The viscosity is then used to place
these liquids in a hazard packaging group depending on their
viscosity/flashpoint relationship. The U. S. Department of
Transportation permits the use of these regulations for
transhipment of hazardous material within the U.S. when bound for
foreign destinations.
1.5?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. 1.6?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. |
