The older Z87.1-2003 standard tests required 20 hits. For goggles, they are shot with a 6.35mm, 1.05 gram, steel ball at 300 fps (4.39 joules).Įach test is repeated six times under the current Z87.1-2010 standard. For glasses, they are shot with a 6.35mm diameter, 1.05 gram, steel ball at 150 fps (1.09 joules) These may be marked with "W", "U", "L", "V", "H", and "S" (some with numbers) on the frame or lenses.įor the "Z87+" impact standard, the relevant "High Velocity" impact is testing: There are also Z87 ratings for light filters, UV filters, IR filters, tints, etc. Protection marked "Z87" and "Z87-2" (no "+") ARE NOT IMPACT RATED.ĭifferent types of eyewear are required to meet different standards to be Z87+ impact rated (see below). This you be looking for eye protection marked "Z87+" or "Z87-2+" (the "-2" is used in the 2010 standard for RX lenses). The "Impact protector" (Z87.1-2010+) and "High impact" (Z87.1-2003+) sub-standards are the impact part of Z87. The the basic Z87.1-2010 and Z87.1-2003 standards do not REQUIRE impact testing. There's several different versions of the ANSI Z87 standard with the current version being Z87.1-2010. Keep in mind these are minimum standards particular goggles or glasses may exceed these minimums. ![]() ![]() A small-fast projectile can penetrate barriers that a slow-large projectile will fail to penetrate and vice versa, depending on construction of the barriers and shape/density of the projectile. Material penetration is a factor of both projectile velocity and weight, not just pure energy numbers. I thought you guys might be interested.Īll of the fields in my area have a max velocity of 500 fps with 0.2g BBs, though some fields I've been to will allow up to 550 fps at 60 feet. I recently decided to buy some prescription safety goggles, and did a LOT of research before eventually spending $350.
