In the past, masonry systems have been the solution of choice for projects requiring added resistance to damage. Now, however, a new generation of high-performance engineered gypsum panels and coating systems has transformed the entire field of abuse resistance.
USG’s abuse resistance portfolio includes enhanced panels that have up to five times the impact resistance of regular wallboard. This is achieved through both higher density and the presence of fiber mesh embedded in the backside of the wallboard. USG offers two types of panels that provide moderate abuse resistance and two types of panels that provide high levels of abuse resistance.
Due to higher demand of these products and systems new testing standards were developed and old ones were revised and updated to reflect the industry’s requirements. The main ASTM standard for abuse classification is ASTM C1629 which specifies the levels of performance. Annex A1 describes test methods for testing products for Hard Body Impact Resistance.
ASTM C1629 makes reference to three other test methods for abuse resistance: ASTM E695 for Soft Body Impact, ASTM D4977 for Abrasion resistance, ASTM D 5420 for Indentation Resistance.
