I don't think any of us here are involved in production scenarios. I thought the EU mandated testing, but I'm not sure. Certainly heard complaints about testing and changing designs as a result.

Last I saw, testing is fairly inexpensive. Less expensive than I would have done it for, that's for sure. It might be worth it to do it locally. But you have to find out the laws in your market.

There was talk about having small builders do testing here in the U.S., but it hasn't been instituted. The insurance company the most small builders use was talking about it. I am guessing they haven't had enough losses to require it.

ETA: I thought I had the European standards, but I can't find them.

I didn't dive too deeply, but the CEN standards apply to all of Europe, but aren't enforced in every country. Most countries allow self-certification, but CEN urges certified labs do the testing. ISO says that Germany is bound to implement the ISO standard. Maybe the ISO standard allows self-certification, I didn't see information about that
