Well, darling, ASTM F2413 is the standard specification for performance requirements for protective (safety) toe cap footwear, while ASTM F2412 covers the test methods for foot protection. So, in simpler terms, F2413 tells you what your boots should do, and F2412 tells you how to test if they actually do it. They're like peanut butter and jelly - different, but meant to be together.
