Simply put to insure quality...
There are many kinds of calibration standards out there. We at, Exaxol, make ICP, AA, Ion Chromatography, EPA, pH, and Conductivity standards among other things. They all have different shelf lives due to there matrix or stabilizers. Many require high purity acids to dissolve in solution and over time CO2 from the air will make carbonic acid in your standardized solution. This will affect pH dependent solutions and add impurities.
Tolerances are a big deal in many industries and even mechanical and digital measuring devices such as scales and electrodes need to be checked annually to maintain accuracy in your work.
I added a link to a more lengthy pH discussion if you were looking for more than a short answer response!

Three commonly followed standards for constructing and installing cabling include the Telecommunications Industry Association (TIA) standards, specifically TIA/EIA-568 for commercial building cabling, the National Electrical Code (NEC) for electrical safety, and the Institute of Electrical and Electronics Engineers (IEEE) standards, such as IEEE 802.3 for Ethernet networking. These standards ensure proper performance, safety, and interoperability of cabling systems. Adhering to these guidelines helps prevent issues like signal interference and ensures compliance with local regulations.

"Every 3 days" refers to a frequency of occurrence where an event happens once every three days. This means that after an initial event, the next occurrence will take place three days later, and subsequently every three days thereafter. This pattern continues consistently, with the event happening regularly at intervals of three days.
The phrase "once every 3 years" can be expressed as "triennial." This term refers to an event or occurrence that happens every three years. Alternatively, you could also say "every three years" for clarity.
A handheld turbidity meter measures turbidity of a water sample. The meter is calibrated using standard samples from the meter manufacturer. The picture with the three glass vials shows turbidity standards of 5, 50, and 500 NTUs. Once the meter is calibrated to correctly read these standards, the turbidity of a water sample can be taken.

THIS IS RIGHT OUT OF THE MANUAL FOR 97 OLDS BRAVADA THAT I OWN....The compass is self-calibrating, so it does not need to be manually set. However, if C (Calibration) is displayed, the compass will need to be calibrated. You may also place the compass in a non-calibrated mode by pressing and holding the MODE and US/MET buttons simultaneously while in the COMP/TEMP mode. After about 10 seconds, the compass will display C and you can release the buttons. Drive the vehicle in a complete 360 degree circle three times at a speed of less than 5 mph, and the compass will function normally. Once the calibration is complete, the compass will return to a compass reading
try getting into calibration mode and driving three tight circles in an empty parking lot(without a cop watching preferably).
vanilline - 81°C to 83°C (range-1.5°) Acetanilide - 164°C to 165.7°C (range-1.0°) Caffeine - 235.6°C to 237.5°C (range-1.0°) All three standards starting & Ending points is within 1.5° only. In our operational way also it covers minimum, middle & Maximum calibration covered.
general industry, construction, and maritime are the 3 main standards of OSHA.
Borax has a high purity level, making it suitable for accurate and reproducible calibration. It has a stable chemical composition, which ensures consistent results over time. Borax is easily accessible, cost-effective, and not as sensitive to air and moisture as some other primary standards.
In Secret Agent Mission 5 once you have the three "elements" you return and G will tell you to put them into the "calibration machine". I had this same problem- not being able to find it. Next to the goggles is a funnel thing that you click when you have one of the elements in your hand- it should go in.

Something that happens every three years is a triennialevent.
