read somewhere that z87.1 (minimum rating) is only rated for a single 1 J impact.

z87.1+ covers higher J and multiple impacts.

It doesn't outright say it from what I recall, but the test was a ball bearing dropped from a certain height. The rating mentions something about maximum amount the material is allowed to deflect indwards, also the penetration resistance of the object. I think I did a calculation on the weight and height of the object being dropped and it equated to about 1J.

I dont' think I was able to find any literature regarding the drop test on 87.1+ but it mentioned that part of that standard was multiple impact.
I futz with V2s, V3s and V6s. I could be wrong... but probably, most likely not, as far as I know.
