A: It is not rated as such.

Q: 2. Are these cards waterproof? I'd like to take them diving.

A: While they are coated for normal wear and tear, these are not made for underwater use. I would instead recommend Amphibico Aluminum White Balance & Color Chart - 7 x 11 (B&H # AMACWB0711) which is specifically made for diving. A low end solution would be a simple piece of duct tap on a fin.
