Le présent document décrit une méthode pour le dénombrement des micro-organismes revivifiables à 37 °C. Il a été conçu pour servir de référence dans certaines normes françaises pour l'analyse microbiologique de types d'eau particuliers (eaux potables, eaux de piscine). En conséquence, son application directe en dehors de ses usages prévus, implique de vérifier qu'il est adapté au type d'eau analysé et à la précision recherchée, et d'indiquer quelles options ou modifications sont adoptées dans ce but.
