When something is labeled as "professional grade" should we take it to mean there is some classification or ranking system in place? Or might this label simply mean the product is good enough to meet the needs of a pro?
How strict is the definition of "grade" here?
I'm trying to understand whether this a fact-based term or an opinion-based term.

Professional grade (or commercial grade) is a term to distinguish from general use or consumer grade products. It is intended to communicate a more durable product with the expectation that it will work better or longer in an environment where it is used more regularly.
I do not believe the term is legally regulated and it can be used simply as marketing but the meaning is still the same whether it is used appropriately or not.
Primarily, consider the vendor. If you are buying from a general consumer store, it may indicate a slightly more durable product or a marketing ploy. If you are at a trade store or commercial vendor that caters to professionals, the term will likely be more accurately used.
