	Approvals & Engineering Review EZClear's repair compounds and procedure has been approved by the following organizations: U.S. Army Aviation Command – Helicopter Division American Airlines MD-80 Technical Manual General Dynamics/Gulfstream Aerospace Boeing Integrated Defense Systems / Mil Rotorcraft Bombardier Aircraft / Learjet U.S. Army TM EZClear has been incorporated into the U.S. Army TM (Reference 1-1500-204-23-10, C3) Download copy of TM Stress Craze Test Test Overview Three stress craze tests were conducted in partial accordance to Federal Specification PP- 560B at the US Army Research Laboratory, Aberdeen Proving Ground, MD from April 26th through April 29th, 2005. The purpose of these tests was to evaluate the EZClear Polish, a product of Plastek, LLC (Redwood City, CA) for its potential usage on the acrylic windshield and windows of the US Army UH-60 (Blackhawk) helicopters. The primary objective is to prove that the polish does not adversely affect (i.e. chemical attack) the acrylic material while undergoing a tensile stress of 2000 psi. Conclusions Based upon these observations from the three stress craze experiments conducted, the EZClear polish does not deteriorate or cause irreparable damage to the acrylic material. There was no craze forming at the surface even at the fulcrum in which the (tensile) stresses are highest. Through visual inspection, all three samples showed no loss of clarity even after 21+ hours. One can conclude that the EZClear polish does not adversely affect the acrylic material. NVG Test Test Overview Cell-cast acrylic test specimens conforming to MIL-P-5425 were obtained. The material used in this report has the same MIL specifications as the window applications of Blackhawk and Apache helicopters. Baseline measurements of haze and transmittance were recorded for all virgin pieces. Subsequently, the acrylic samples were subjected to a controlled abrasion event to simulate exposure that acrylic windshields experience in dust/sand environments. After exposure to the abrasion event, haze and transmission measurements were again recorded. Specimens were then treated with Plastek’s EZ-Clear™ polish, and haze and transmittance were again recorded. Conclusions Results show that the treatment with EZ-Clear™ polish restored the haze and transmittance to near-virgin levels. Finally, the specimens were evaluated for clarity using night-vision equipment. The EZ-Clear™ polish was found to have no adverse effect on night-vision clarity.
