- The item must be user-serviceable (if applicable).
- You cannot be a large corporation.

It's a bit like how you'll see things advertised as being made of "aircraft grade" aluminum.
I'm an aircraft repairman, there is no such thing as "aircraft grade" at least in the United States; the aviation industry does not maintain its own standards for metallurgy, it uses SAE standards, and a lot of different alloys get used in aircraft for various applications. Sheet metal skin and structures is usually 2024-T3, you'll see 6061 or 6065 in castings, hell they make pure aluminum rivets for fastening placards. So most things that say "aircraft grade" on them usually mean they're 6061-T6 or similar. which is legal for use in aircraft construction if its properties are called for in the design. It's just some wank they can legally get away with putting on retail packaging.
For me aircraft grade aluminum is right up there with space age technology. The space age was 50 years ago.
Ugh I always hated that phrase. Like, space age technology is ball point pens, Tang, and those MPET blankets you find in first aid kits. Oh and freeze dried ice cream.
It really really does not mean shit at this point.
