Talk:Lot number

A VIN number is a sertial number. It is not a lot number. That is an error on this page. The picture is not a projectile. It is a shotgun shell. A projectile leaves the cartridge or shell.

When does a manufacturer change lot numbers?
This article needs information on when a manufacturer would be inclined to increment the lot number on products from a line.

As a hypothetical example with pharmaceuticals, I would assume they change the lot number every time a new "batch" of drugs has to be prepared.

More confusing is when they would change the lot number on a production line that runs nearly 24/7 without stop. Especially with a less regulated product than pharms.

What would constitute a new lot? Is there some ISO standard regarding lot numbers? I'm sure the criteria is very different from one line to the next, one product to the next etc. So I could see there being a lot of information about this. VoidHalo (talk) 20:47, 1 August 2023 (UTC)
