Racing equip. specifications...

[over 40 five oh driver]

Trying to educate myself on this subject for future reference, racing, and nice to know stuff. What I can't seem to track down is, what do the terms "Snell 95 rated", or, "SFI 41.2" mean as it relates to safety equipment? In other words, who certifies equipment for drag racing? How is it certified? Against what standard? Been searching the Web and haven't come up with anything. Any help would be much appreciated.
