Thermostats are critical devices for precise temperature maintenance in laboratory, medical, industrial, and scientific research. Their metrological verification is conducted based on existing regulatory frameworks, such as ISO/IEC 17025:2017 and ISO 10012:2003 standards. However, these standards are not sufficiently refined regarding the assessment of temperature uniformity, stability, and measurement uncertainty in thermostats. In Uzbekistan, the metrology system is based on UzNIM and O‘z DSt standards but is not yet fully aligned with international requirements. According to DKD-R 5-1 and DKD-R 5-6 guidelines, certain uncertainties in evaluating temperature uniformity—such as hysteresis and insulation resistance—have remained unaccounted for. Current metrology trends in 2025, including the AdMet-2025 conference and the growth of the smart thermostat market (7.8%), necessitate new standards. Against the backdrop of increasingly complex technological processes, temperature measurement errors exacerbate safety concerns. Therefore, improving the regulatory framework is essential, as it can enhance accuracy up to 0.1 °C and ensure global competitiveness.
