Vitreous and porcelain enamels - Terminology - Part 2: Visual representations and descriptions (ISO 19496-2:2017)

This standard establishes a system for the cataloguing of defects in sheet steel
enamelling. It serves for a consistent language use concerning the designation and
characterization of enamelling defects. This standard is limited to detectable defects and
does not purport to fully take into consideration all occurring types of defects. It does not
evaluate enamelling defects; the classification carried out serves for the conveyance or
practical knowledge.

Email und Emaillierungen - Terminologie - Teil 2: Darstellung und Charakterisierung (ISO 19496-2:2017)

Diese Norm stellt ein System für die Katalogisierung von Fehlern bei der Stahlblech-Emaillierung auf. Sie dient dem einheitlichen Sprachgebrauch bei der Bezeichnung und Charakterisierung von Emailfehlern. Diese Norm ist nur auf erkennbare Fehler beschränkt und erhebt nicht den Anspruch auf vollständige Berücksichtigung aller vorkommenden Fehlerarten. Sie nimmt keine Bewertung von Emailfehlern vor, die vorgenommene Einstufung dient der Erfahrungsübermittlung.

Émaux vitrifiés - Terminologie - Partie 2: Représentations visuelles et descriptions (ISO 19496-2:2017)

ISO 19496-2:2017 établit un système de catalogage des défauts d'émaillage sur tôles d'acier. Il vise à maintenir la cohérence de la terminologie utilisée pour la désignation et la caractérisation des défauts d'émaillage. Le présent document se limite aux défauts détectables et n'a pas pour but de prendre en considération tous les types de défauts pouvant survenir. Il n'évalue pas les défauts d'émaillage; la classification réalisée est un moyen de communication des connaissances pratiques.

Steklasti in keramični emajli - Terminologija - 2. del: Vidni prikaz in opis (ISO 19496-2:2017)

Ta standard vzpostavlja sistem za katalogizacijo napak v emajlih jeklenih plošč. Namenjen je za dosledno jezikovno uporabo glede označevanja in opisa značilnosti napak v emajlih. Ta standard je omejen na napake, ki jih je mogoče zaznati, in ne obravnava vseh vrst napak, ki se pojavljajo. Ne ocenjuje napak v emajlih; izvedena razvrstitev služi za prenos ali praktično znanje.
