ASTM D6005 Slump Resistance Testing for Carpet Adhesives
Slump resistance of a trowel-grade carpet adhesive is determined by using a button slump test apparatus in ASTM D6005. This technique can also visually estimate related troweled bead profile and trowel pickup. The standard final values are expressed in inch-pounds.

Frequently Asked Questions
ASTM D6005 evaluates slump resistance of carpet adhesives. It measures ability to maintain position without flowing, helping ensure proper application, bond uniformity, and performance on vertical or inclined surfaces during installation.
Key parameters include adhesive application thickness, substrate orientation, temperature, conditioning time, and measurement method. Controlled conditions ensure accurate assessment of adhesive flow and slump behavior.
The test measures distance or degree of adhesive movement after application. Results indicate resistance to flow and ability to maintain placement during installation.
ASTM D6005 applies to carpet adhesives used in flooring systems where maintaining position during application is critical for proper bonding and performance.
ASTM D6005 results depend on environmental conditions and application method. It may not fully represent field conditions, requiring additional evaluation for temperature variations and real-world installation practices.
