BS EN ISO 10111:2019

What is ISO 10111 about?

ISO 10111 is an international standard that specifies guidelines for determining the average surface density over a measured area of anodic oxide or a coating deposited autocatalytically, mechanically, by chemical conversion, by electrodeposition, by hot-dip galvanizing, and by chemical or physical vapour deposition. Using gravimetric and other chemical analysis procedures that have attained some degree of national or international standardization.

A variety of procedures are described and include:

• Gravimetric procedures for chemical or electrochemical dissolution of the coating or the substrate to determine the coating surface density
• Gravimetric procedures for weighing the uncoated substrate and the coated (finished) specimen to determine the coating surface density
• Analytical procedures that utilize dissolution of the coating

Note: With the exception of the gravimetric method as described in ISO 3892, ISO 10111 does not give the measurement uncertainties of the methods cited.

Who is ISO 10111 for?

ISO 10111 on metallic and other inorganic coatings is applicable to:

• Ships and boat manufacturers
• Heavy equipment manufacturers
• Automobiles Industry
• Trains and aircraft manufacturers
• Oil and gas pipelines Industry

Why should you use ISO 10111?

The inorganic coating also called conversion layers are non-metallic, very thin coatings on a metal surface and serve to protect against corrosive attacks. Metal coatings are coatings that are applied to metal in order to protect the metal and reduce wear and tear.

ISO 10111 helps you to determine the average surface density of anodic oxide or a coating deposited autocatalytically, mechanically, chemically, via electrodeposition, hot-dip galvanizing, or chemical or physical vapour deposition across a measured area.

The best industry guidance in ISO 10111 can help you determine the average surface density in the metallic and inorganic coating in order to protect the metal from rust, corrosion, dirt, and debris to achieve the desired surface finish and appearance.

What’s changed since the last update?

BS EN ISO 10111:2019 supersedes BS EN ISO 10111:2002, which is withdrawn. BS EN ISO 10111:2019 includes some technical changes with respect to BS EN ISO 10111:2002. These include:

• A gravimetric method has been added for weighing the uncoated substrate and the finished sample
• The surface area increase caused by surface roughness has been considered to obtain a more realistic estimation of local geometric coating thickness
• Annex A, which gives reagents for etching or stripping solutions, has been changed to informative as other solutions can be applied
• Reagents in Annex A that referred to no longer existing standards or which contain hazardous chemicals have been removed
• Outdated and uncited references in the Bibliography have been removed
