[Another dumb question that I feel I will get torn up for if I asked in the main forums]

What does the NJS certification mean?

Is it that all parts with the NJS logo are within a certain tolerance? or built a certain way?


I am only asking because I see it everywhere and tend to pay no attention to it, and was wondering if I should. I tried to search but I couldn't find anything (even on google, mind you computers hate me)
