Q: Does it come with a Certificate of analysis or compliance?

I don’t recall seeing anything like that. I just checked the case to see if it was under the foam, but it doesn’t come apart. Each weight was accurate on several different scales though.

Q: How do you use those to calibrate scale with ounces only?

you can calculate by converting grams to ounces : 1 oz = 28.41 grams.

Q: What is the diameter of the largest weight?

Largest weight ( 100 grams ) is 3 inches in diameter and 3/4 of an inch side to side.

Q: The list indicates they are made of stainless steel, but then says they are made from “solid feeling coated metal”. Are they actually electroplated?

What I can confirm is the larger weights are magnetic the small ones that look like cut sheet metal are not magnetic. Usually stainless is not magnetic however with all the variations of it I can't say for sure if thats still true. I wanted the set basically to make sure the HO race cars track scale was repeating the same weight and so the others could check there own scales to make sure they didn't show up and there car was to light for the class they race in. I wouldn't depend on them if you need certified weight standards for scales used to sell stuff. But if you have a certified scale and the weight of the standard is off you can see if it repeats and gives you the same weight as when it was certified. I found that some of them are spot on and some are off a tiny bit if my scale is correct. They are not super high quality but for what I needed it for they work. I am not sure how else to really test the metal to tell what it is made of other than scraping or sanding them down but then they would be lighter and I still might not know what they are made of if they didn't change color. I hope maybe this little additional information is helpful.
