@ Lurkingknight:

I believe the standards are a 1/4 inch steel bearing shot at 200 FPS towards the centre of the lenses. I don't have an OH&S/CSA standards book with me but I do recall something similar to what I described above. I'll see if I can find a pdf of it.

EDIT: Here, although I do believe the high velocity impact is more pertinent to us than the drop ball test here.

http://www.elvex.com/Facts-What-chan...Z87.1-2010.htm

Below is a summary of the tests and requirements for safety spectacles, goggle and face shields. Please note that the original document is 47 pages long, and it contains a lot of detailed information. This summary is not claimed to be complete.

Quote:
High Velocity Impact

Face shields shall be capable of resisting impact from a 6.35 mm (1/4 in) diameter steel ball traveling at a velocity of 91.44 mps (300 fps).

Goggles shall be capable of resisting impact from a 6.35 mm (1/4 in) diameter steel ball traveling at a velocity of 76.2 mps (250 fps).

Spectacles shall be capable of resisting impact from a 6.35 mm (1/4 in) diameter steel ball traveling at a velocity of 45.7 mps (150 fps).

For sample size of 6, no failure may occur (Z87.1-2003 required 20).
BTW If anyone is wondering, here is the OH&S for Canada Z94.3-07 (Rev 2014) but it's $100 http://www.ccohs.ca/products/csa/27017372007 You might be able to find the big book at your public library.
