Temperature standards are established benchmarks used to ensure accurate temperature measurements across various fields, including science, industry, and healthcare. These standards help maintain consistency and reliability in temperature readings, which are crucial for processes like manufacturing, food safety, and medical diagnostics. Organizations such as the International Organization for Standardization (ISO) and the National Institute of Standards and Technology (NIST) develop and maintain these standards. They provide guidelines for calibration and testing equipment, ensuring that thermometers and other temperature-measuring devices deliver precise results in different environments and applications.
