Here is the spec sheet for this motor[http://www.aerotech-rocketry.com/uploads/4e952284-bb4b-4943-8904-9a0719e8ee3a_AT%20H550ST%20SU%20jun%2019.pdf]. Interestingly enough, SSI will be using this motor for its L1 certifications.

Using this motor as an example, we know that this motor is classified in the range of impulse from 160 Ns - 320 Ns. The 550 denotes that the motor's average thrust is 550 N. The ST denotes what type of propellant is in the casing. In this case, ST stands for "Super Thunder". Aerotech has cute names for their different types of propellants. They often only denote the color of the flame. Finally, the 14 denotes that the motor will fire its ejection charge 14 s after burnout unless it is adjusted, as indicated by the A. Motor delay times can be adjusted with a motor delay tool (otherwise known as a proprietary screwdriver, here is a link to buy one[http://www.buyrocketmotors.com/aerotech-universal-delay-drilling-tool-for-dms-motors/].
