So the conclusion is: Test your eye protection, whatever it is, like the article says.
I have heard those words before but forgot about them and often get confused with the meanings. Thanks for the explanations, good read.
I have seen a lot of auto darkening helmets

I suppose there's also the possibility that the equivalents of ANSI or OSHA or whoever sets the standards for welding lenses in your country, may use a different system or terminology than we do here in the states, which could make most of what I'm saying here largely irrelevant.
Probably. I think we are also a bit careless when it comes to safety measures. Like Ive seen DIY videos on YT that makes me think the maker is being a bit paranoid about safety only to then read the comments telling them all the other safety measures they skipped and all I can think of is "I would have done it worse" lol.
