Reemplaza a: DD ISO/TS 19036:2006+A1:2009
This document specifies requirements and gives guidance for the
estimation and expression of measurement uncertainty (MU)
associated with quantitative results in microbiology of the food
It is applicable to the quantitative analysis of:
products intended for human consumption or the feeding of
environmental samples in the area of food production and
samples at the stage of primary production.
The quantitative analysis is typically carried out by
enumeration of microorganisms using a colony-count technique. This
document is also generally applicable to other quantitative
most probable number (MPN) techniques;
instrumental methods, such as impediometry, adenosine
triphosphate (ATP) and flow cytometry;
molecular methods, such as methods based on quantitative
polymerase chain reaction (qPCR).
The uncertainty estimated by this document does not include
systematic effects (bias).
