the ‘Steel Guard’ set-up. The forklift is traveling at 5 miles/hour or 7.33 feet/second at initial impact with the guardrail. The forklift is driven in reverse so as not to puncture the rails with the forks and to better distribute the impact force between both rails. Test results: The impact stopping time is assumed to be one second.IBHS Articles: Learn more about - Shingle Performance Ratings .

The short answer: markings on the frame and lenses themselves indicate the type of testing that a pair of safety eyewear has undergone and passed per ANSI standards. Z87 = basic impact rating; Z87+ = high-velocity impact rating; However, PRESCRIPTION safety eyewear receives a different set of markings: Z87-2 = basic impact rating The impact test is a method for evaluating the toughness, impact strength and notch sensitivity of engineering materials. Engineers test the ability of a material to withstand impact to predict its behavior under actual conditions. Many materials fail suddenly under impact, at flaws/cracks or notches. The most common impact tests use a swinging .
The Two-Factor Score (speed and memory) provides an additional summary score approach for interpretation of the test data.
