I am told they taste like drywall and taxes. https://www.nist.gov/news-events/news/2020/02/nist-releases-new-standard-cigarette-testing-flammability-mattresses-and https://www.nist.gov/news-events/news/2020/02/nist-releases-...

- ryancw 2mo ago400 cigarettes actually! Not too bad.
- throwup238 2mo agoThat’s $508 for two cartons for 400 cigarettes total, so $1.27 per cigarette. They’re not characterized like the peanut butter, they’re just manufactured to a specific QC standard. California/New York prices are easily $0.75/cigg so it’s not that much more expensive.

- selimthegrim 2mo agoNow I wonder what the GOST ones were like
- andy99 2mo agoI had seen the cigarette. But but not the meat which costs $2,690 for four tuna-can size cans and is a mix of pork and chicken Thinking of a concept for a restaurant meal along the lines of a calibrated fried spam dinner, that costs ~2k for about a can worth, fried like they do in Hawaii. Come to think of it, would love to see an “iron chef- calibrated foods” edition.

- cyphar 2mo agoFor more context, sample reference materials from the NIST reference catalogue are not meant to be exceptionally high purity examples of the sample -- SRMs are usually commercially-produced products. The real value is that each sample comes with a datasheet with incredibly detailed and accurate measurements that are (as you said) used for calibration of measuring devices in industrial settings. To quote a Veritasium video about the topic from a few years ago[1], "the thing you're paying for is not the peanut butter, it's the knowledge of exactly what is in the peanut butter".

- buildsjets 2mo agoTruth. I once paid nearly $500 for a set of 17 certified, calibrated wooden pencils, with documentation showing that each one met their rated hardness levels of 9H thru 6B. And for $500, they don't even come with erasers, that is an added-cost option. https://www.gardco.com/product/pencil-hardness-test-kit-astm-d3363-jpia/01t5I0000023pqaQAA https://www.gardco.com/product/pencil-hardness-test-kit-astm...
- foobarian 2mo agoCan I ask why :-) Sounds like an interesting project.
- cwillu 2mo agoHis link includes procedures, which suggest he was testing the hardness of some surface coating or similar: > For the pencil hardness test, reference ASTM D3363, pencils of increasing hardness values are moved over the surface in a precisely defined way until one lead damages the surface. Surface Hardness is defined by the hardest pencil grade which just fails to damage the surface. > Observe the pencil track. Sufficient pressure must have been applied either to cut or damage the coating or to crush the lead pencil point. > If neither coating damage or pencil point crushing is observed, repeat the test until a definite observation is made. > If scratching or damage of the surface occurs, proceed with the next softer pencil grade and repeat the testing process until a pencil lead grade is found which crushes and does not damage the coating. > If crushing of the hardest lead should occur, the coating is therefore extremely hard and is beyond the measuring range of this test
- georgeburdell 2mo agoYes, it’s a bit frightening to know what a hidden dependency NIST is on many things. In my industry, all calibrations ultimately derive from physical NIST standards for resistance, frequency, etc.
- masklinn 2mo agoIt’s frightening that… NIST is doing the very thing it was established to do back when it was called the Bureau of Standards?
- GolfPopper 2mo agoI suspect the fear comes from both seeing NIST as a single point of critical failure, and perhaps also that it is a far less resilient and/or far more vulnerable, institution than may have been previously realized.
