Dans les secteurs techniques, les termes \u00ab calibrer \u00bb, \u00ab ajuster \u00bb et \u00ab \u00e9talonner \u00bb sont souvent utilis\u00e9s de mani\u00e8re interchangeable. Ils ont pourtant chacun une signification diff\u00e9rente. Nous vous expliquons ici leurs diff\u00e9rences.<\/h4>\n

Calibrage<\/h2>\n

Le calibrage consiste \u00e0 comparer<\/strong> un instrument de mesure \u00e0 un \u00e9talon de r\u00e9f\u00e9rence<\/strong>, sans y apporter aucune modification. On d\u00e9termine ainsi l’\u00e9cart entre l’indication de l’instrument et la valeur r\u00e9elle.<\/p>\n

Le r\u00e9sultat est un certificat ou un rapport de calibrage indiquant les \u00e9carts mesur\u00e9s.<\/p>\n

R\u00e9glage<\/h2>\n

Le r\u00e9glage consiste \u00e0 ajuster ou \u00e0 corriger<\/strong> un appareil de mesure afin qu’il mesure avec la plus grande pr\u00e9cision possible. Cette op\u00e9ration est g\u00e9n\u00e9ralement effectu\u00e9e apr\u00e8s un \u00e9talonnage, lorsqu’il s’av\u00e8re que l’\u00e9cart est trop important. L’appareil est ajust\u00e9 m\u00e9caniquement, \u00e9lectriquement ou via un logiciel.<\/p>\n

La s\u00e9quence logique est donc la suivante :<\/p>\n

    \n
  1. \u00c9talonner pour d\u00e9terminer l’\u00e9cart<\/li>\n
  2. R\u00e9gler si n\u00e9cessaire pour corriger cet \u00e9cart<\/li>\n
  3. R\u00e9\u00e9talonner pour v\u00e9rifier le r\u00e9sultat<\/li>\n<\/ol>\n

    \u00c9talonnage<\/h2>\n

    L’\u00e9talonnage est un processus officiel<\/strong>, r\u00e9glement\u00e9 par la loi, au cours duquel une autorit\u00e9 comp\u00e9tente (en Belgique, le SPF \u00c9conomie \u2013 service M\u00e9trologie) v\u00e9rifie si un instrument de mesure est conforme aux exigences l\u00e9gales. Si l’instrument est approuv\u00e9, il re\u00e7oit une marque d’\u00e9talonnage (cachet ou sceau).<\/p>\n

    La \u00e9talonnage est obligatoire pour les appareils utilis\u00e9s dans le cadre de transactions commerciales ou lorsque la protection du consommateur est requise, tels que :<\/p>\n

      \n
    • les balances dans les magasins<\/li>\n
    • les pompes \u00e0 essence<\/li>\n
    • les taxim\u00e8tres<\/li>\n
    • les compteurs d’eau, de gaz et d’\u00e9lectricit\u00e9<\/li>\n<\/ul>\n

      Quoi?<\/strong><\/td>\nConstater une anomalie<\/td>\nCorriger l’\u00e9cart<\/td>\nAutorisation l\u00e9gale<\/td>\n<\/tr>\n

      En r\u00e9sum\u00e9 : on proc\u00e8de \u00e0 un calibrage pour conna\u00eetre la pr\u00e9cision de mesure d’un appareil, \u00e0 un r\u00e9ajustement pour am\u00e9liorer cette pr\u00e9cision, et \u00e0 une \u00e9talonnage pour prouver l\u00e9galement qu’il est conforme aux normes.<\/p>\n <\/div>\n
