Only a government-accredited agency can evaluate and certify ("approve") to those safety standards, at least in North America.
No self-declaration is permitted there.
It's a long snakey path to follow safety legislation in any country, who is the "authority having jurisdiction", who makes it law that products have approvals.
The liability for a product failing a safety claim is what keeps most companies from selling gear with fake approvals. I see a few Japanese companies with no formal safety approvals, only claims to meet x standard.
Wow, someone still has an FTP site. Sorry but I can't get to it. It won't answer a ping and FTP will timeout. If you downloaded it and feel it could be of interest, just upload it on this site or put it on Googledocs. You could also just describe the test/s you would like to see ran.
Google shows the title as:
"PRODUCT SAFETY: Expanding Markets Mean ... - National Instruments"
North America. – National standards and laws (OSHA). – NRTL certifications, descriptive reports and N.A. Marks (UL/CSA). – UL/CSA standards similar to IEC
The proof is the product having a Certification Agency's sticker with logo and file number, or that in the owner's manual.
UL Certifications Directory
Intertek Product Directories
These directories list Brymen, Uni-Trend, Fluke, Mastech, Flir, Keithley, Klein, Keysight etc. multimeter safety certifications giving proof the product was tested and passed.
My position is the Sanwa multimeters are high quality builds but unknown as far as safety, misleading in their 61010 claims. I'd want to know there are no blatent design/assembly blunders making a clearance violation allowing unexpected arcing, for example.
And if you think the harbor freight meter is bad , then check this:

Lucky one on the mains
"... a company or a product that is not listed is not necessarily untested and does not necessarily fail to meet the regulation (UL/EN/CSA 61010 in this case).
"... a company or a product that is not listed is not necessarily untested and does not necessarily fail to meet the regulation (UL/EN/CSA 61010 in this case).
Unless I'm misunderstanding you, I don't agree - ma and pa can't test compliance to a safety standard in their garage, write up a report and say it's all good. Too much chance of corruption and mistakes.

Slide 18 for the suggestion of a test...
Slides 21 ~ 23 as good references when you are analyzing or making modifications on a DMM.
Anyhow, I just thought it was nice how they presented the information. Quite clear in my opinion.
I have a question about a clamp meter Unit 204A that has intertek / ETL logo and a S.N. Number

From here it looks good but check this on the manual (see attachment) On the temperature sensor 1K resistor in series. You plug the meter into 230V in this mode and its bye bye...
So they may ommit some functions during the certification?
Looks like True stopped posting.001 as well.
Joe, one interesting meter that you may consider testing in the future is the nice PM300 from Sanwa; it is rated for CATIV 300V / CAT III 600V and is quite well built. It is protected by a GDT and a Varistor on a string of resistors.
Think the SANWA would survive to higher levels than this little Brymen? Did Dave do anything to it electrically in his reviews?Just a hunch but I suspect so, given that Sanwa is a very reputable japanese brand that would not lie about CAT ratings.
Dave did not put it through its paces, though.
I purchased a new unit after my PM55A had failed, only to find a PM55 I gave to a friend also failed. I tested a PM55 I had and it too had failed. The replacement? Well, it tested good (testing 5V in auto mode, and shorting probes, that's it...); after a month when I went to use it to test a low voltage DC circuit again, it showed low battery ... and sure enough it failed too.
Also found another issue with the BM867s. If it’s sitting in series with the PA monitoring current it goes bloody mental when you key down. Fluke, fine. Keysight, fine. Hmm. This is why I haven’t dropped my review yet. I still like it but not for that.
