If no failure occurs, increase the height (and thus the impact energy) by a set increment (e.g., 2 inch-pounds) and drop the weight onto a fresh area of the panel. If failure occurs, decrease the height for the next drop. This article will explore every aspect of ASTM
The test works by dropping a standard weight from varying heights to deform the coating and its underlying substrate. It identifies the precise point at which the coating fails, establishing an "impact value" measured in inch-pounds (in-lb) or Joule-meters (J). Direct vs. Reverse Impact The standard outlines two distinct types of impact testing: If failure occurs, decrease the height for the next drop
Note: If you are exporting products to Europe, you might need to purchase ISO 6272-1:2017. However, many labs use ASTM D2794 because the equipment is interchangeable with minor adjustments.
