Techopedia explains Production Grade
To an extent, production grade is actually a marketing buzzword, as there is no formal definition for production grade qualities and characteristics. The IT implication is similar to comparing a commercial grade appliance to one for residential use in that it is implied that production grade IT products can withstand heavier and more frequent use.
