EDIT: Your volume is still slightly larger...looks like roundoff error. But we're close.
Hard to do it on a adding machine only 4 sig figs no 1/x button or Y^X. I should have gone into engineering instead of finance / accounting.
Where did you find the testing protocol for the 1" sphere dropped 50". That energy level requirement for the z87.1 rating is rather low considering that most field limits are ~1.7j. This makes me VERY leary of shooting glasses that only meet this standard. I found this: http://www.labsafety.com/refinfo/ezfacts/ezf251.htm
Perhaps we should be requiring people to have the high impact z87.1 rated lenses over the basic? If the testing protocols calls for ~0.9j impact to be resisted (and the lenses supposedly tossed after an impact), are standard shooting glasses insufficient?
Do you know what ruins airsoft?
