TS ISO 11843-1

TS ISO 11843-1 defines the terms and definitions used for detecting a difference between the actual state and the basic state of a system. This part of the series establishes a common vocabulary for capability of detection in measurement methods and clarifies how the ability of a measurement result to distinguish a change is expressed and discussed.

Where capability of detection fits in measurement work

In general technical terms, capability of detection is about whether a meaningful change in a system can be separated from noise, scatter, and uncertainty. That makes the topic important in metrology, statistical evaluation, and quality-control work, where the issue is not only whether a measurement produces a value, but whether that value can reliably distinguish a change from the normal background. This standard organises that idea at the conceptual level; the content identified here is terminology and definitions.

The terminology framework provided by this part

• Centers the distinction between actual state and basic state.
• Provides common terminology for detection, measurement methods, and related concepts.
• Clarifies the key expressions used when interpreting measurement performance.
• Forms the conceptual basis for more detailed evaluations in later parts of the series.

Accordingly, TS ISO 11843-1 is less about prescribing a specific test procedure or numeric acceptance limit and more about giving measurement practice a structured vocabulary for detectability and change detection.
