A process to distinguish plumbing parts, either individually or as combined into a plumbing product, in which one of two types of coatings have been applied to the parts, with the parts being visually indistinguishable by the type of coating. The parts are illuminated with a non-visible light operating at a frequency which will be absorbed by only one type of coating. The parts may be coated with an essentially organic coating or an essentially inorganic coating. Only one of these coatings will absorb the non-visible light and such absorption will be displayed so as to distinguish between parts having the different types of coatings.
Cette invention concerne un procédé de reconnaissance de pièces de plomberie prises individuellement ou faisant partie d'un assemblage, lequel procédé fait appel à l'application de deux types de revêtements non différenciables à l'oeil nu. Les pièces doivent être éclairées par une source de lumière noire ayant une fréquence qui sera absorbée par un seul des deux types de revêtements. Les pièces peuvent être enduites d'un revêtement essentiellement organique ou essentiellement inorganique. Un seul des deux revêtements absorbe la lumière noire, ce qui permet de différencier les pièces d'après leur type de revêtement.
