Safety Standards
ANSI Z87.1 is the baseline safety requirement for all ESS products. The majority of our products are held to the extended ballistic requirement of U.S. MIL SPEC MIL-PRF-32432A - OVER 6 TIMES THE KINETIC ENERGY LEVEL OF ANSI Z87.1.
HIGH VELOCITY IMPACT
ESS protective eyewear surpasses the test for high-velocity impact protection as defined by the American National Standards Institute (ANSI). Per ANSI Z87.1, a quarter-inch steel ball is shot from three different heights, and at seven different angles. To pass the high-velocity test, no contact between the lens and eye is permitted during impact. In addition, no frame parts or lens fragments may be ejected during impact.
HIGH MASS IMPACT
ESS protective eyewear also surpasses the protection requirements for high-mass impact. Within ANSI Z87.1, the high-mass impact test requires that the lens be hit by a 500- gram metal spike (over a pound of weight) dropped from a height of 51.2 inches (over four feet). To pass the test, no frame parts or lens fragments may be ejected during impact.
ANSI Z87.1 HIGH VELOCITY IMPACT TESTING
.25 in diameter steel ball 150 Ft/sec for spectacles
.25 in diameter steel ball 250 Ft/sec for goggles
U.S. MIL SPEC MIL-PRF-32432A
The U.S. military standard requires that ballistic eyewear must be able to withstand up to:
.15 caliber at 700-725 ft/sec for spectacles
.22 caliber at 580-590 ft/sec for goggles.
