There are several ANSI standards that reflect different properties. In this case you want ANSI Z87.1, which is the standard for high velocity impact protection. If it doesn't state that it meets or exceeds this particular rating I would err on the side of caution and assume it doesn't.
As for the CSA standard I can't say for certain as to what it pertains to. It may simply be indicating that the product is not made from harmful materials. Anyone able to provide more info on CSA ratings?
