Ce document propose un mode opératoire de détermination de l'intervalle de confiance associé à des résultats de méthodes de mesure en l'absence d'échantillon de référence. Ce mode opératoire s'applique quand la norme NF ISO 5725 (parties 1 à 6) n'est pas utilisable sur site à cause de la combinaison de la variabilité de la méthode de mesure et de celle du procédé à mesurer sans qu'il soit possible de la discriminer.
