This document specifies a method for the measurement of metal coating thickness by first forming a
step between the surface of the coating and the surface of its substrate and then measuring the step
height using a profile recording instrument. It covers the instrumentation characteristics and the
procedure appropriate to this specific application of profilometric methods.
The method is applicable to the measurement of thicknesses of metal coatings from 0,01 μm to 1 000 μm
on flat surfaces and, if appropriate precautions are taken, on cylindrical surfaces. It is highly suitable
for the measurement of minute thicknesses but, for thicknesses of less than 0,01 μm, surface flatness
and surface smoothness are very critical and, accordingly, the method is not suitable for use down to
the lowest level of measurement usual for electronic stylus instruments. The method is suitable for
measuring coating thicknesses when preparing coating thickness reference standards.

This document specifies protection criteria for determining the AC corrosion risk of cathodically protected pipelines.
It is applicable to buried cathodically protected pipelines that are influenced by AC traction systems and/or AC power lines.
In the presence of AC interference, the protection criteria given in ISO 15589-1 are not sufficient to demonstrate that the steel is being protected against corrosion.
This document provides limits, measurement procedures, mitigation measures, and information to deal with long-term AC interference for AC voltages at frequencies between 16,7 Hz and 60 Hz and the evaluation of AC corrosion likelihood.
This document deals with the possibility of AC corrosion of metallic pipelines due to AC interferences caused by conductive, inductive or capacitive coupling with AC power systems and the maximum tolerable limits of these interference effects. It takes into account the fact that this is a long-term effect, which occurs during normal operating conditions of the AC power system.
This document does not cover the safety issues associated with AC voltages on pipelines. These are covered in national standards and regulations (see, e.g., EN 50443).

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 suitable for fused sprayed coatings deposited using self fluxing alloys.
The test supports quality assurance and is intended to be applied for the purpose of coating optimisation by identifying the influences of coating parameters and spray materials on the coatings's quality. Furthermore, the coating in particular for cold sprayed coatings can be compared with the characteristics of similar solid materials and the coating's quality can be assessed.
This test is not recommended for thin coatings (coating thickness < 500 µm), since massive scattering of results is to be expected here. Due to the size of the specimens, it is particularly suitable to apply the tubular coating tensile test for coating processes that use a concentrated spray jet and a highly focused spray spot, as in the case of cold spraying, high velocity flame spraying (HVOF) or plasma spraying. Applying the tubular coating tensile test for coating processes that use a broad spray jet, such as flame spraying and arc spraying, may require special spraying measures, e.g. the use of a template to ensure a nearly vertical impingement angle.

This document specifies a method for using phase-sensitive eddy-current instruments for non-destructive measurements of the thickness of non-magnetic metallic coatings on metallic and non-metallic basis materials such as: a) zinc, cadmium, copper, tin or chromium on steel; b) copper or silver on composite materials. The phase-sensitive method can be applied without thickness errors to smaller surface areas and to stronger surface curvatures than the amplitude-sensitive eddy-current method specified in ISO 2360, and is less affected by the magnetic properties of the basis material. However, the phase-sensitive method is more affected by the electrical properties of the coating materials. In this document, the term “coating” is used for materials such as, for example, paints and varnishes, electroplated coatings, enamel coatings, plastic coatings, claddings and powder coatings. This method is particularly applicable to measurements of the thickness of metallic coatings. These coatings can be non-magnetic metallic coatings on non-conductive, conductive or magnetic base materials, but also magnetic coatings on non-conductive or conductive base materials. The measurement of metallic coatings on metallic basis material works only when the product of conductivity and permeability (s, μ) of one of the materials is at least a factor of two times the product of conductivity and permeability for the other material. Non-ferromagnetic materials have a relative permeability of one.

This document specifies procedures for designing, preparing and using precracked specimens for
investigating susceptibility to stress corrosion. It gives recommendations for the design, preparation
and use of precracked specimens for investigating susceptibility to stress corrosion. Recommendations
concerning notched specimens are given in Annex A.
The term “metal” as used in this document includes alloys.
Because of the need to confine plasticity at the crack tip, precracked specimens are not suitable for the
evaluation of thin products, such as sheet or wire, and are generally used for thicker products including
plate bar and forgings. They can also be used for parts joined by welding.
Precracked specimens can be loaded with equipment for application of a constant load or can
incorporate a device to produce a constant displacement at the loading points. Tests conducted under
increasing displacement or increasing load are dealt with in ISO 7539-9.
A particular advantage of precracked specimens is that they allow data to be acquired, from which
critical defect sizes, above which stress corrosion cracking can occur, can be estimated for components
of known geometry subjected to known stresses. They also enable rates of stress corrosion crack
propagation to be determined. The latter data can be taken into account when monitoring parts
containing defects during service.

This European standard defines the requirements to be specified in the coating specification for a thermally sprayed coating. It applies to components and workpieces made of metallic or non-metallic materials that are to be partially or completely coated with thermally sprayed coatings. The coating may be made of metals, metal ceramics, oxide ceramics or plastics. Additional requirements for the coating manufacturer that are not coating-specific should be included by defining the technical supply conditions according to EN ISO 12670.
The requirements defined in this standard should be met by a component-related thermal spray procedure specification (TSPS) prepared by the coating manufacturer. The thermal spray procedure specification should be documented and component-related to ensure traceability. For details, see prEN 17002 (project stage).
Proof that the requirements of the coating specification are met by the application of the thermal spray procedure specification can be provided by performing a component-related procedure qualification according to EN 15648.
If specific coating requirements cannot be specified by the customer, they should be agreed with the contractor on the basis of the requirements for the sprayed coating - e.g. against fretting wear at high temperatures - and on the basis of the contractor's past experience.

This document specifies two accelerated corrosion-test procedures, Methods A and B, for the
comparative evaluation of metallic materials with or without permanent corrosion protection or
temporary corrosion protection in outdoor salt and/or acid rain environments. It also specifies the
apparatus used. The two tests involve cyclic exposure of the specimens to acidified salt spray, “dry” and

The particular advantages of the two tests over conventional accelerated tests, such as the neutral salt
spray (NSS) test as specified in ISO 9227 lie in their better ability to reproduce the corrosion that occurs
in outdoor salt and/or acid rain environments. They are also useful for evaluating cosmetic corrosion.
Method A is applicable to
— metals and their alloys,

tests for production parts. Some of these quantitative tests can, however, be useful in research and
development work.

This document describes a test method for the determination of the resistance of vitreous and porcelain
enamelled articles to attack by alkaline liquids at temperatures between 25 °C and 95 °C. The apparatus
used is a hexagonal vessel in which six enamelled specimens or a tetragonal glass bottle in which four
enamelled specimens are simultaneously tested.
NOTE 1 The resistance to any alkaline liquid can be determined. However, the test method was originally used
for the determination of the resistance to hot detergent solutions, within the neutral and alkaline range, used for
washing textiles.
NOTE 2 Since detergents are continually subject to alterations in their composition, a standard test solution
is specified which, in respect to its alkalinity, wetting properties and complexing behaviour, can be considered
as a typical composition for the detergents present on the market. The pH value and alkalinity of the standard
test solution depend on the proportions of sodium tripolyphosphate, sodium carbonate and sodium perborate
present; sodium tripolyphosphate acts simultaneously as a complexing agent. The wetting properties of the
standard test solution are obtained by the addition of alkylsulfonate. A higher sodium perborate content is not
considered necessary since the effect of oxygen on enamel is unimportant and an increase in the perborate
content does not cause any significant alteration in the alkalinity of the standard test solution. The testing of
different enamels using this standard test solution and other test solutions (including 5 % sodium pyrophosphate
solution) has justified the use of this standard test solution for determining the resistance of enamels to hot
detergent solutions.

This standard applies to electrodeposited zinc and zinc-alloy coatings on iron and steel with Cr(VI)-free passivation. The
zinc-alloy coatings contain nickel or iron as alloying agents (referred to as zinc/nickel and zinc/iron coatings, respectively).
The main purpose of the coatings or coating systems is protecting iron and steel components against corrosion.
The standard prescribes the designations to be used for the above coating systems and specifies minimum corrosion
resistances to be achieved in specified test procedures and the minimum coating thicknesses required to achieve them.
