Contest certification is dependent on the motor being a model rocket motor and it being readily available. It's not automatic at all but it is independent of the certifying group.

To answer your question I used to look at that list regularly, but not lately. It was always substantially more valuable than any list TRA produced and I for one appreciate that.
|
That list is produced in cooperation with TRA and CAR. Each of the three groups posts the certification data (At least what you see on the list. Sometimes more.) to a mailing list that we all get. The S & T volunteered to maintain the list for everyone to use. TRA links to it on their website. I'm not sure about CAR.

BTW there is an error in the list of manufacturers. In the motor tables they list both Kosdon and Kosdon/AT but it is not in the legend.
|
I'll check into that.

That pdf file had some motors highlighted in color but it is not clear from a legend why, unless I just missed it.
|
All the highlighted motors have (HP) in front of them. We were asked to do that to make it more obvious that those are not model rocket motors even though their impulse class might lead you to believe they are.

Since I remember HPR from well before it was called HPR by NAR, I find it quite interesting the sheer number of K, L, M motors, and the fact NAR lists N, O motors. There is a Cesaroni "full O" on that list.
|
The last time I counted there were over 800 certified motors from 1/8A to O!

I think the policy of declaring some motors HPR despite being below the model rocket federal thresholds, and arbitrarily adding a thrust limit and a spark limit is a bad idea. The spark limit could be by age of access instead. Redefining motors (by and in NFPA codes) along weight and thrust is an unwise policy IMHO. It conflicts with actual laws and regulatory positions.
