'''Z87:''' ANSI certified for regular impact. For safety eyewear to pass the basic Z87 standard, it must pass the ''Drop Ball Impact Test''. This test involves a steel ball (that is one inch in diameter and weighing roughly 2.4oz) dropped from a test height of 50 inches. For eyewear to pass, the lens and frames must remain intact. Eyewear rated at Z87+ are better, having passed the Drop Ball Impact Test as well as a High Mass Impact Test, High Velocity Impact Test, and a Penetration Test. | '''<u>Z87</u>:''' ANSI certified for regular impact.

'''D4:''' ANSI certified for splashes and dust particles. Safety goggles are intended to protect eyes against dust, splash, and droplet hazards. Goggles form a protective seal around the eyes, preventing liquid, chemicals, or dust from entering under or around the goggles. Ventilated goggles allow air circulation while providing protection against airborne particles, dust, liquids, or light. | '''<u>D4</u>:''' ANSI certified for splashes and dust particles.

'''Z87 and D4 rating is the ''minimum'' recommended.''' Even better for NETs are safety eyewear that are ANSI rated Z87+ and D3-5, anti-fog, and include indirect ventilation around the eye area. | '''Z87 and D4 rating is the ''minimum'' recommended.'''
