    As a cybersecurity engineer, I cannot hype up NIST enough. They maintain this security database that contains all known software vulnerabilities in existence. Every major company, government and military is using this database to check for vulnerabilities in their infrastructure. Thank you NIST.

      @anon you do realize the fact that they sell the references that are required for companies to meet national standards means that NIST is able to be self sustaining, right? If your complaint was for making your peanut butter 2ç more expensive because they have to calibrate their equipment every so often, it would make sense.

      @Ben Hook we use SECP256K1 in blockchains, Bitcoin, Ethereum, which isn’t a NIST curve. It’s Koblitz curve. SECP256R1 on the other hand is a NIST curve. I used to wonder why Satoshi chose non-standard curve. I assume this is one of the reasons why.

      Here in Germany we have DIN (German Institute for Normation / Standardization). The standardize a lot of stuff, from paper sizes (just think of DIN A4) to combustion fuel compositions. I don't know for sure if they have their own SRMs or if they use EN, ISO or NIST SRMs but they standardized a LOT of materials and regulatories.

    The Charpy test is indeed an important standard test for steels. It measures the toughness, or resistance to brittle fracture, using a standard notched specimen. Materials prone to brittle fracture are to be avoided (or mitigated). Ductile fracture does not sound so good either, but if something is going to fail, ductile failure is safer and preferable as it requires exceeding design loads to achieve this. Brittle failure is of concern because it can occur at less than design load conditions.
    The typical units of measure are energy (absorbed) in Ft-Lbs for imperial unit system, Joules for SI units. Metals and most solid materials become more brittle as temperature is decreased. Higher values measure in this test are better than low values. Brittle high strength steel may yield single digit values, whereas low strength austentic stainless steel may yield 300+ Ft-Lbs, meaning it takes a lot more energy to break it in a notched impact specimen, even though it is not nearly as strong.
    Different metal alloys and heat treat conditions will have different temperatures at which they become brittle (Ductile to Brittle Transition Temperature, or DBTT). The temperature at which the test is performed is based on design standards and factors such as the end product's minimum design temperature, and the material's expected DBTT. If the material is produced correctly, it will meet or exceed certain impact energy values at a given temperature. If not, it may produce low values and indicate sub-standard material.
    The notch of the specimen, which is the designed point of failure is machined to precise dimensions for the purpose of consistency. I am a Metallurgical Engineer and thought I should delve into sharing my personal understanding of that part of the video.

    • Steve_11 12
      Steve_11 12 9 days ago

      @Scott Rackley Good point. Toughness is not a required or necessary property in some materials and some applications. It is in structural and pressure containing products, but typically not in tooling. In fact in tool steels, low toughness often times is very acceptable in order to get the high strength or wear resistance that is required. Hence tool steels when they fail, tend to fail in a brittle manner.

      Charpy is just one way to measure one variable in a steel. Many times in tool steel you don't really care too much about that value, and are looking for wear resistance, such as drawing forms.

      @teranyan If a single SRM batch requires hundreds of labor hours and a million dollar lab and tens of thousands of dollars in reagents and supplies to analyze, yeah its justified. Use your brain for once. Consumer peanut butter isn’t $1000 a unit because consumer *factories* have economies of scale and don’t need teams of scientists to test every batch, precisely because standards agencies like NIST produce the standards needed to calibrate the industrial testing equipment in the factory.

    I'm a pharmacist and always ensured my students knew that the temperature monitoring devices (basically a thermometer) for the refrigerator/freezer that holds medications must have a certificate of calibration tracing its accuracy back to NIST, as well as ensuring they knew those devices do in fact "expire" and should be re-calibrated or, more practically, replaced.

    Do those standards include common, almost standard, manufacturing errors?

    • sciencedude
      sciencedude Month ago

      I would hope so. The point of a standard reference material is not to have a perfect material free of defects, but rather to have a material that has been analyzed so extensively that it can be used to calibrate measurement tools. So if I have a sensor that's made to detect a particular set of manufacturing errors, I callibrate it using a reference material with a precisely measured amount of each error. My sensor is accurate and calibrated correctly when it measures the same amount of error measured by a reputable source, such as NIST.

We call them SARMs though, standard analytical reference materials. We use NIST steel spheres to calibrate our density measurement machines. They produce a great product, and are vital to industries like mine. Keep up the good work guys!

      @ben let's say that you know a scale can accurately measure 100 lbs, 150 lbs and 200 lbs because you used only references of those three weights to calibrate it. Does it mean the scale can only measure those 3 weights? No, it means it can measure any weight between 100-200 lbs within a small margin of error.

    • LabGecko

      @ben to expand on what James said, take note that the NIST rep said they take samples. Chemically those apples are very similar, but to account for those small differences that's why they blend them. That's why it's a "standard" instead of "chemical model of Granny Smith" apples. It's a baseline, nothing more, nothing less.

    Working in the lab of a sewage treatment plant, was interesting for a while, but then became insanely boring, but one neat thing was the fact that the more accurate our scales were, and also our ability to dispense the necessary items for testing, the smaller the test sample could be, and therefore the less of those necessary items would be used as well. Our scale was so accurate that we could weight our fingerprints. We would have elementary school kids tour the plant from time to time, and we would pick one to pickup a beaker while we turned our back, then we could correctly tell them how many fingers they used to pick it up with. We did have to instruct them to use the pads of their fingers not the tips to make it fair, but as long as they played fair, we had a 100% correct “guess”, and the kids absolutely loved it. We also typically picked a kid that was somewhat socially awkward, which made them the big shot hoping to help them socially.

    • A Flailing Duck
      A Flailing Duck 2 months ago +5

      @Unified Theory of Life There's a difference between radiant heat dissipation and kinetic energy transmission. It's the principle used in controlled demolitions of structures that were designed to withstand these heavy impacts. While a giant ~205000kg jet slamming into that building at 750km/h would only have generated around 7-8 giganewtons, the explosion of 90000 liters of jet fuel added anywhere between 70 and 150 giganewtons, which brings it to the realm of what is used to bring down even larger buildings. For comparison, the demolition of the significantly taller Mina Plaza only took around 6000kg of explosives, which was of a class that would have generated only around 50 to 80 giganewtons, barely over half the force that plane crash event generated. While the efficacy of force delivery is certainly much higher in controlled demolitions, it's not hard for 30+ floors of falling structure to make up for the rest, especially when structural integrity gets compromised more and more with each impact. Additionally, most demolitions prefer to go over the force requirement if possible and add more explosives / reduce section distance between explosives, not because there isn't going to be enough force, but that it's simply cleaner of a job when there's less structure to take impacts. I'm sure the fires didn't help things stay structurally sound either, but to be honest they may very well have been completely irrelevant at this point.
      The structure doesn't have to be exposed to radiant heat, just vibrate enough to the point that it lowers its structural integrity so that it can no longer support the weight of what's above. Once that gives, impact force from the falling section will create further vibrations that further destabilize the structural integrity of what remains. If you're lucky, or unlucky in the case of demolitions, it stays standing. Most of the time, it does not.
      On a related note, this is the reason why skyscrapers (and increasingly even mid-rise buildings nowadays) built on the pacific ring of fire (Japan, New Zealand, Taiwan) employ technologies which allow for the structures to take reduced vibrations from earthquakes. The main difference is the way the energy is delivered, with earthquakes predominantly consisting of maintained lateral forces, as opposed to one big delivery from an event like 9/11 or a controlled demolition, but earthquakes can easily deliver enough kinetic energy to destabilize a building.

      Hi There Month ago

      Most bigger peanut butter brands do not contain aflatoxins in any major amount and there is no need to fear for liver cancer from eating most peanut butters in developed countries. There's a bit more that can get by with smaller brand natural peanut butters but again, not something to really worry about. On that note, aflatoxin is a toxin found in molds from peanuts, corn, other grains and in less developed countries that make peanut butter in less sanitary conditions, more may slip by. Derek makes purposefully misleading comments like this all the time.
