| 1 | Scope: This Standard gives guidelines for the evaluation of uncertainty in quantitative microbiological analyses based on enumeration of microbial particles by culture. It covers all variants of colony count methods and most probable number estimates. | |
| 2 | Two approaches, the component (also known as bottom‑up or step‑by‑step) and a modified global (top‑down) approach are included. | |
| 3 | The aim is to specify how values of intralaboratory operational variability and combined uncertainty for final test results can be obtained. The procedures are not applicable to methods other than enumeration methods. | |
| 4 | The standard also includes key concepts, microbiological methods, choices of approach, the component approach to the evaluation of operational uncertainty, the global approach to the determination of the operational uncertainty and combined uncertainty of the test result, | |
