It always a good idea to bench test a new prop. Start with a 10 second blast at full throttle. Then stop and test the temperature of the motor, esc and battery by touching them. Warm is OK but if they are so hot you can’t hold on to them, stop, that’s too much prop. If it passes, try a 30 second blast, if it passes. Try a 60 second blast, if it passes you will likely be OK. It’s a good idea to take the temperature of everything right after a flight. Keep in mind a prop that works when it’s 70 may cause overheating when it’s 95+.
