Temperatuurivahemikku

Temperatuurivahemikku is a term used in Estonian-language technical and scientific texts to denote a temperature interval—the range of temperatures over which a device, material, process, or organism functions as intended or remains stable. The interval is defined by a minimum temperature Tmin and a maximum temperature Tmax, and is commonly reported in degrees Celsius (°C) or kelvin (K). In some contexts, the word refers to an acceptable operating temperature window, while in others it describes the stability range of a phase or property.

Across disciplines, temperatuurivahemikku is used to specify conditions for performance, safety, or validity. In engineering, electronics, and manufacturing, equipment often lists its operating temperature range (e.g., −40°C to 85°C). In chemistry and materials science, the temperature window indicates where reactions occur efficiently or materials stay intact without decomposition. In biology, organisms or enzymes have a viable temperature range for growth or activity, with activity typically increasing with temperature up to an optimum before denaturation occurs.

Representations may include Tmin and Tmax with the inclusive or exclusive interpretation depending on the context. Temperature intervals are fundamental for design, testing, and quality control.
