How to cite this on a certificate

16 CFR 1110.11(a)(2) requires each applicable rule to be stated separately. Listing it like this satisfies the form of the requirement:

16 CFR Part 1241 — Safety Standard for Crib Mattresses

Citing a rule does not make it applicable, and 16 CFR 1110.11(a)(2) asks for every applicable rule. Whether this one applies to your product depends on its materials, construction and intended user age, which is your determination to make.
