Abstract

The method involves carrying out a sampling on a surface with a white paper or cloth. A state of the dirty surface is compared with gray shades of a support e.g. laminated support, so as to determine a cleanliness level of the sampled surface, where the gray shades are rated from 0 to 9 and are standardized. An independent claim is also included for a device for evaluating a cleanliness level of a surface.

Description

La présente invention concerne un dispositif permettant d'évaluer par comparaison le niveau de propreté d'une surface. Elle est constituée d'un support cartonné ou plastifié sur lequel sont représentés différentes nuances de gris. Ces nuances de gris sont notées de 0 (pour la plus claire) à 9 (pour la 5 plus foncée). Les nuances de gris sont normalisées. Un prélèvement est réalisé sur une surface avec un papier ou un tissu blanc et l'on compare l'état d'une surface souillée avec les nuances de gris du support. La comparaison permet de donner une note allant de 0 à 9 au niveau de salissure d'une surface prélevée. 1 The present invention relates to a device for evaluating by comparison the level of cleanliness of a surface. It consists of a cardboard or plasticized support on which are represented different shades of gray. These shades of gray are rated from 0 (for the lightest) to 9 (for the 5 darkest). Grayscale is normalized. A sample is made on a surface with a white paper or cloth and the state of a soiled surface is compared with the shades of gray of the support. The comparison makes it possible to give a score ranging from 0 to 9 at the level of soiling of a sampled surface. 1
