TS 5822-3 ISO 5725-3
Accuracy (trueness and precision) of measurement methods and results - Part 3: Intermediate measures of the precision of a standard measurement method
This part of ISO 5725 specifies for intermediate precision measures due to changes in observation conditions (time, calibration, operator and equipment) within a laboratory.

About This Item
TS 5822-3 ISO 5725-3 addresses the intermediate precision behaviour of a standard measurement method within the broader framework of accuracy of measurement methods and results. Its focus is the variation in results that can arise inside one laboratory when observation conditions change, such as time, calibration, operator, and equipment.
What intermediate precision means
In general technical use, precision describes how closely repeated measurements agree with one another. Intermediate precision extends beyond the narrow repeatability condition: the work is still carried out in the same laboratory, but results may be influenced by day-to-day changes, recalibration, different analysts, or different equipment settings. This makes intermediate precision a practical indicator of how stable a measurement method is under routine laboratory variability.
Technical scope reflected in this part
- Determination of intermediate precision measures within one laboratory
- Effects of changes in time-related observation conditions
- Effects of calibration changes
- Effects of operator and equipment variation
The ISO 5725 series separates the concepts of trueness and precision when characterising method performance, and this part is concerned specifically with the intermediate-condition component of precision. In practice, it supports laboratory method evaluation, interpretation of result spread, and comparison of measurements obtained on different days or by different operators. This listing refers to the 2000 TSE adoption of the standard and it has since been withdrawn.
