repeterbara

Repeterbara is a Swedish adjective meaning capable of being repeated. It describes processes, measurements, or results that can be performed again under the same conditions and are expected to yield the same outcome. The noun form repeterbarhet refers to the property of repeatability. In scientific and engineering contexts, repeterbarhet is a fundamental quality for measurements and tests, indicating that random variation is small enough that repeated trials under identical conditions produce consistent results. Typically, repeterbarhet is assessed by repeated measurements using the same operator, the same instrument, and the same procedure within a short time frame; the spread of results is summarized by statistics such as the standard deviation or the coefficient of variation.

Repeterbarhet is essential for calibration, quality control, and method validation. High repeterbarhet does not guarantee that a result will be the same in different laboratories or under different conditions; that broader reliability falls under reproducibility, where variations in operators, equipment, or environments are allowed. Conversely, low repeterbarhet indicates that even small changes or measurement noise can alter outcomes, undermining trust in the method.

The term is used across fields including physical sciences, engineering, manufacturing, and software testing when consistent results under controlled conditions are important. Etymologically, repeterbara comes from repeter, via Latin repetere, reflecting the idea of repeating an action until the outcome is stable.
