ISO 16773-1 Corrosion Protection by Organic Coatings Laboratory Testing Service: A Comprehensive Guide

Standard-Related Information

ISO 16773-1 is an international standard that specifies the requirements for corrosion protection by organic coatings in various industries. The standard is developed and published by the International Organization for Standardization (ISO) and is widely adopted across the globe.

The standard provides a framework for evaluating the performance of organic coatings on steel, aluminum, and other metals used in construction, transportation, and other industrial applications. It covers aspects such as coating thickness, adhesion, impact resistance, and corrosion resistance.

Standard Numbers and Scope

  • ISO 16773-1:2020 - Corrosion protection by organic coatings - Part 1: General principles

  • ASTM B-117-2018 - Standard Practice for Operating Salt Spray (Fog) Apparatus

  • EN 15926-2:2013 - Paints and varnishes. Coating materials and coating systems for exterior masonry and concrete surfaces. Test methods. Part 2: Determination of resistance to water penetration

  • TSE 1015-2019 - Corrosion protection by organic coatings

    • Standard Development Organizations

    The ISO standard development process involves collaboration between experts from various countries and industries. The process typically takes several years, involving multiple drafts, reviews, and approval stages.

    Some notable standard development organizations involved in the development of ISO 16773-1 include:

  • International Organization for Standardization (ISO)
