Btw, I always found Australian UVA standard odd, they require a sunscreen to protect from 90% of rays in the 320-360 nm range which means UVA-II only, while EU regulations require same from a bit more - 370 nm, all the critical wavelength equations. Aus standard also says nothing about how good is the UVA protection, kinda like the UVA seal, it just says it conforms to the law, is why PPD I find a slighty more informative system. Anyway is still insufficient given the insidious nature of UVA-I, but still better than nothing.
