Paints and varnishes - Corrosion protection of steel structures by protective paint systems - Part 3: Design considerations (ISO 12944-3:2017)
ISO 12944-3:2017 deals with the basic criteria for the design of steel structures to be coated by protective paint systems in order to avoid premature corrosion and degradation of the coating or the structure. It gives examples of appropriate and inappropriate design, indicating how problems of application, inspection and maintenance of paint systems can be avoided. Design measures which facilitate handling and transport of the steel structures are also considered.
Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Teil 3: Grundregeln zur Gestaltung (ISO 12944-3:2017)
In diesem Dokument werden die Grundregeln zur Gestaltung von mit Beschichtungssystemen zu ver-sehenden Stahlbauten festgelegt, um vorzeitige Korrosion und Schäden der Beschichtung oder des Bauwerks zu vermeiden. In der Norm sind Beispiele für geeignetes und ungeeignetes Gestalten gegeben, und es wird gezeigt, wie Schwierigkeiten beim Auftragen, beim Überwachen und beim Instandsetzen von Beschichtungs¬systemen vermieden werden können. Gestaltungsregeln, welche die Handhabung und den Transport von Stahlbauten erleichtern, sind ebenfalls enthalten
Peintures et vernis - Anticorrosion des structures en acier par systèmes de peinture - Partie 3: Conception et dispositions constructives (ISO 12944-3:2017)
ISO 12944-3:2017 traite des critères fondamentaux de conception des structures en acier qui doivent être revêtues de systèmes de peinture afin d'éviter la corrosion prématurée et la détérioration du revêtement ou de la structure. Il donne des exemples de bonnes et de mauvaises dispositions, en indiquant comment les problèmes d'application, du contrôle et de l'entretien des systèmes de peinture peuvent être évités. Il examine également les dispositions qui facilitent la manutention et le transport des structures en acier.
Barve in laki - Protikorozijska zaščita jeklenih konstrukcij z zaščitnimi premaznimi sistemi - 3. del: Osnovna pravila za načrtovanje konstrukcije (ISO 12944-3:2017)
Ta dokument obravnava osnovna merila glede zasnove jeklenih konstrukcij, ki jih je treba zaščititi z zaščitnimi premaznimi sistemi, da se prepreči prezgodnja korozija in degradacija premaza ali konstrukcije. Podaja primere ustrezne in neustrezne zasnove ter opisuje, kako se je mogoče izogniti težavam pri nanosu, pregledu in vzdrževanju premaznih sistemov. Upoštevani so tudi pogoji zasnove, ki omogočajo lažje upravljanje in prevoz jeklenih konstrukcij.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
