Quality Control Tests for Adhesion of Paint on the Panels of Tactical Rigid WallShelters, Phase 2

摘要

At the request of the U.S. Army Natick Research, Development and EngineeringCenter, a practical method was developed for measuring the adhesion of paints applied to shelters. As recommended in the Phase I report, a pull-off test based on the use of a commercially available pneumatic testing device was chosen. The procedure includes ways of controlling the substrate stiffness, a parameter that affects the test results, and a process for obtaining acceptable levels of adhesion for a particular substrate. The estimated precision (standard deviation) of the method is 9 percent. In a pilot study to determine the extent to which small differences in surface preparation would affect differences in pull-off test results, it was found that, at least for aluminum, the procedure was insensitive to small differences in surface preparation.
