Camper conversion rules in Finland question – where do I find them?

I am trying to compare camper conversion rules in some European countries.

I managed to find the information that there is a government-issued list of specifications, not unlike the British one here: [https://www.gov.uk/government/publications/registering-a-diy-caravan](https://www.gov.uk/government/publications/registering-a-diy-caravan) that can be downloaded from the Finnish government’s websites but in Finnish only.

I was so far unsuccessful to google it, for an obvious linguistic reason, so I thought perhaps someone is familiar with the link, or can be so nice and google them for me quickly… From then I guess machine translation should be sufficient for my needs, but I simply failed to find the link… Any help will be greatly appreciated.
