Here's a weird question. When I buy C25, is it 25% CO2 by mass, volume, or what?
I was socially distant when social distancing wasn't cool.

The relevant standards will tell you but, like you, I don't have them.Chips O'Toole wrote: ↑Thu Oct 12, 2023 5:54 pm Here's a weird question. When I buy C25, is it 25% CO2 by mass, volume, or what?
However, BOC states: The designation system shall be based on volumetric percentages.
