Solid rocket motors have a fairly standardized labeling system. On the casing (or reload) itself there is a three-part code which denotes what the total impulse range is, the average thrust, and the delay grain length. All these numbers are in standard metric units.

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].

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.
