I'm not a native English speaker. I'm Italian and I'm doing my thesis in the Netherlands. I have to write technical documents for non-native English speakers, so I didn't receive any advice for choosing which one dialect (British or American) to use, as long as I stay consistent.
My doubt comes from the fact that, while British is the original form, American is more related to my field of interest (electronics) and, I would say, more related to the spread of English as universal language.
Is there any reason because I should use one over the other?
My audience is not well specified because the document is meant to be conserved, but most likely European people, not necessarily Dutch.
