Designation:D5267–97
Standard Test Method for
Determination of Extrudability of Cartridge Adhesives
This standard is issued under the fixed designation D 5267; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method measures the amount of force neces-
sary 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 the standard. The values given 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 appro-
priate safety and health practices and determine the applica-
bility of regulatory limitations prior to use.

3.1 Definitions—Many terms in this test method are defined
in Terminology D 907.
4. 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 nec-
essary to extrude a cartridge adhesive at a given temperature.
This provides the formulator with results that can assist in
