Lämpötilavälistä

Lämpötilavälistä is a Finnish linguistic form commonly found in technical and scientific Finnish. It derives from the base noun lämpötilaväli, meaning a temperature interval or temperature range. The ending -stä (or -stä) is the elative case, used to indicate origin or source, so lämpötilavälistä translates roughly as “from the temperature range.” In practice it is used inside phrases to refer to a specific subrange of temperatures within a larger window, for example when describing data, conditions, or measurements that are taken from a defined interval of temperatures.

A temperature range is a continuous set of temperatures bounded by a lower limit and an upper limit. The bounds are typically given in degrees Celsius (°C) or kelvin (K), and the interval may be written in formats such as 0–5 °C, 15–25 °C, or 293–298 K. Ranges can be inclusive or exclusive depending on the measurement or specification, and in many contexts the exact treatment of the endpoints is stated in accompanying documentation.

In technical contexts, lämpötilavälistä is used to specify the conditions under which experiments, tests, or measurements are considered valid. It appears in datasheets, method descriptions, quality control procedures, and research reports. Examples include stating that samples were stored lämpötilavälistä 2–8 °C, or that a device operates normally within lämpötilavälistä 20–30 °C.

Related concepts include lämpötilaväli as the general interval, sekä terms such as toiminta-alue (operating range) and lämpötilan vaihtelu (temperature fluctuation). The exact interpretation of lämpötilavälistä depends on context, but it consistently signals conditions drawn from a defined temperature interval.
