4.1?Several test methods are noted for viscosity determination of Newtonian and near Newtonian flow characteristics. (For adhesives not fitting into this category, Test Method D2556 should be considered.) Four test methods are covered as follows: 4.1.1?Method A?is applicable only to adhesives that will deliver 50 mL in a steady uninterrupted stream from one of the cups described in Section 5. 4.1.2?Method B?is intended for measuring the viscosity of adhesives covering a range from 0.05 Pa ? s to 200 Pa ? s (50 to 200000 cP) and is limited to materials that have or approach Newtonian flow characteristics. 4.1.3?Method C?is intended primarily as a control method for determining the viscosity of adhesives that have or approach Newtonian flow characteristics. 4.1.4?Method D?is intended primarily as a control method for determining the viscosity of materials that have an equivalent viscosity no greater than approximately 3000 mPa ? s (cP) and is limited to materials that have or approach Newtonian flow characteristics. |

1.1?These test methods cover the determination of the viscosity of free-flowing adhesives. 1.1.1?The limitation of this test method to self-leveling adhesives eliminates thixotropic and plastic materials whose viscosity is a function of the rate of stirring and previous history of the adhesive. 1.2?The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?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. |
