The ANSI Z87+ High-Velocity safety glasses must go through stringent testing. Below you will find the exact testing they must pass to be marketed with the Z87+ ratings.
- High Mass Impact Test: This involves dropping a 500g pointed weight from a height of 127 cm onto the glasses.
- High-Velocity Impact Test: This test shoots a 6.35 mm diameter steel ball at 150 feet/second (approximately 102 mph) at the glasses.
- Durability Test: This test subjects the glasses to exposure to non-ionizing radiation and chemicals.
Safety glasses that pass these tests can bear the "Z87+" marking, which means they offer a higher level of protection than regular safety glasses and are suitable for environments with a risk of high-speed particles striking the wearer's eyes.
For prescription safety glasses to be marked with the ANSI Z87.1+ high velocity, they must meet these criteria.
