ASTM D2979 Pressure-Sensitive Tack of Adhesives Using an Inverted Probe Test Machine

ASTM D2979-16: Standard Test Method for Pressure-Sensitive Tack of Adhesives Using an Inverted Probe Machine (Withdrawn 2019)

This test method covers measurement of the pressure-sensitive tack of adhesives.

This test method is applicable to those adhesives which form a bond of measurable strength rapidly upon contact with another surface and which can be removed from that surface cleanly, that is, without leaving a residue visible to the eye.

For such adhesives, tack may be measured as the force required to separate an adhesive and the adherend at the interface shortly after they have been brought into contact under a defined load of known duration at a specified temperature.
