Standard Test Method for Determination of Extrudability of Cartridge Adhesives

SIGNIFICANCE AND USE
4.1 Cartridge adhesives are typically used at job sites in a wide variety of temperature ranges. These products may be exposed to cold temperatures, where one of the limiting application factors is whether the product can be extruded from the cartridge.  
4.2 The test method quantitatively measures the force necessary to extrude a cartridge adhesive at a given temperature. This provides the formulator with results that can assist in formulation development and the end user with information for use in selecting a product for general usage.  
4.3 By measuring (the ease of) extrusion from the cartridge, the test method can also be used as a quality control tool to measure the shelf life stability of a product.
SCOPE
1.1 This test method measures the amount of force necessary to extrude an adhesive from a cartridge at a given temperature.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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, 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.
