Standards

• Standards Related to Radiation Thermometers and Thermal Imagers
  Infrared Thermometers, Optical Pyrometers and Thermal Imagers all are based on the same physical phenomena of nature but have different standards associated with them.

  Most of the Thermal Imager standards have little to do with temperature measurement (they are mostly about imaging properties) but that situation appears to be due for some changes soon.

• Standards Related to Thermistors
  Most of the Thermistor standards are related to clinical uses of thermistor-based thermometers to measure human temperatures.
• Standards Related to Liquid-In-Glass Thermometers
  Liquid-in Glass thermometers are undergoing some serious changes as the”War on Mercury” heats up (pun intended).

  But seriously, there are many standards for “Glass Thermometers” that are based on the properties of them where mercury is the liquid in the capillary. It will be some time before all the standards are rewritten, but non-mercury devices are on the market already from more than one company.

  Suffice it to say, it appears that there are quite a few tradition-bound standards that cannot accept that more accurate and cost effective temperature measurement devices are already on the market, e.g. RTDs and Thermistors, that have already surpassed fragile glass thermometers.

  Just witness what is available in your local Pharmacy (Chemist) at very competitive prices for use in taking fever temperatures.
