Wait, how did you get the thrust curve here? I don't see how the test stand is instrumented. I'm interested to hear about the grain geometry and propellant formula, so you should make a post on the research section where this discussion is allowed. I'm sure others are curious too and you could get better advice there.
Getting it certified will be a challange. If you are not a manufacturer, or don't intend to go into manufacturing, I don't think the motor will be considered for certification.
If you are going to become a manufacturer (as in, you have already started your company, have all the paperwork for working with the chems and doing this sort of work in your county etc) then you can submit it for certification.
When you say too hot, NFPA 1127 I think has some requirements on max casing temperature. This includes the after-burn heat soak. It's been a few years since I've read it. Anyway, the Research forum is where you want to be posting.

The cost from the certifying organization is a very minor expense...like $50 per motor type from the NAR, and I’m not sure what TRA charges, possibly a deposit to cover the cost of replacement of a load cell if a motor damages it.Anyone know about how much it costs to certify a motor? Just curious if anyone here has gone through that process and the cost.
There’s this from NFPA 1125:There is a facility requirement for the manufacturing license as well, isn't there? That is what shut me off to the idea. You can't build in your garage these days.
I already build these in a dedicated facility

If I started building motors as well, the neighbors will start to worry....

Whoa, whoa, hold on a minute! You build that Jeepy-looking thing? Ok, "T" the thread, motor discussion to research and let's talk about that truck for a sec!
