How can I tell the shelf life of an edding spray can? How long can I store them and when should I use them by?

Our products have a code on the bottom of the can which looks something like this: EXP-50/23. EXP indicates the minimum shelf life, in this example it's calendar week 50, 2023. When stored correctly (10-25°C, relative air humidity max. 60%), we guarantee a minimum shelf life of 10 years for aerosol sprays containing solvent.
