This document specifies a method for non-destructive measurements of the thickness of conductive coatings on non-conductive base materials. This method is based on the principle of the sheet resistivity measurement and is applicable to any conductive coatings and layers of metal and semiconductor materials. In general, the probe has to be adjusted to the conductivity and the thickness of the respective application. However, this document focuses on metallic coatings on non-conductive base materi...view more

This document specifies a field method for the determination of water-soluble chlorides in non-metallic blast-cleaning abrasives. This field method is provided as a kit with all components and premeasured extraction solution. This document differs from ISO 11127-7 in that equal volumes of the sample of abrasive and extraction solution are used for the determination of chloride level in the abrasive. In comparison, ISO 11127-7 uses a weight to volume ratio of abrasive to solvent (deionized water)...view more

This document specifies a method of determining the mass per unit area of hot dip galvanized coatings
on ferrous materials.
Since an exact knowledge of the area of the surface is essential, this document is mainly applicable to
shapes whose areas are easy to determine. If, with heavy samples, the specifications of Clause 7 cannot
be met, then the hot dip galvanized coating mass is determined by another method.

The types of non-metallic abrasive and requirements on each are contained in the ISO 11126 series. The ISO 11126 series and the ISO 11127 series have been drafted as a co...view more

This document specifies a method for measuring the thickness of the individual nickel layers in electroplated multilayer nickel coatings and measuring the potential differences between the individual nickel layers in electroplated multilayer nickel coatings. The measurement of coatings or layer systems other than electroplated multilayer nickel coatings is outside the scope of this document.

This document specifies a method for the determination of the surface abrasion resistance of anodic oxidation coatings produced by sulfuric acid anodizing of aluminium and its alloys. It is mainly intended for the evaluation of external architectural coatings. It is a production control method that relies to a large extent on operator experience and instruction.

This document specifies a field method for the assessment of the surface density of various water-soluble
salts on steel surfaces, before and/or after surface preparation, by conductometric determination. The
individual surface densities of the salt composition like chlorides, sulphates, sodium, etc, cannot be
determined by this method.
This method assesses only contaminants that forms an electrolyte (ions) when in contact with water.
These represent the greater part of the contaminants.

This document specifies the procedure for the determination of coating strength, and hence of cohesive strength in a tubular coating tensile test.
The test is intended to determine the tensile coating strength parallel to the spray layers (normal to the spray direction) and to identify differences in particle bond quality.
The tubular coating tensile test is suitable for sprayed coatings deposited using metallic materials (not carbides and ceramics).
The tubular coating tensile test is not su...view more
