IPKZ - Protection of metals against corrosion

This document specifies a method for the measurement of the local thickness of metallic coatings, oxide
layers, and porcelain or vitreous enamel coatings, by the microscopical examination of cross-sections
using an optical microscope.

This document specifies general principles for carrying out corrosion tests under conditions of constant immersion. Some of these general principles are applicable to other types of corrosion testing.
This document does not cover important procedures for stress corrosion testing, such as those given in ISO 7539 (all parts).

ISO 28706-2:2017 specifies a test method for the determination of the resistance of flat surfaces of vitreous and porcelain enamels to boiling acids, boiling neutral liquids, alkaline liquids and/or their vapours.
This method allows the determination of the resistance of vitreous and porcelain enamels to the liquid and vapour phases of the corrosive medium simultaneously.

This document gives guidelines for the selection of procedures that can be used in the identification and examination of corrosion pits and in the evaluation of pitting corrosion and pit growth rate.

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 methods for the determination of
— the presence of colourless chromate conversion coatings,
— the presence of hexavalent chromium in colourless and coloured coatings on zinc or cadmium or
aluminium-zinc (mass fraction of aluminium: 55 %, within a range of 54 % to 56 % mass fraction)
and zinc-aluminium (mass fraction of aluminium: 5 %) alloys,
— the total chromium content per unit area on zinc and cadmium,
— the mass per unit area of both colourless and coloured coatings,
— the satisfactory adhesion of chromate conversion coatings, and
— the quality of chromate coatings.
These methods are applicable to
— colourless and coloured chromate conversion coatings containing trivalent and hexavalent
chromium in varying proportions and produced by either chemical or electrochemical processes,
and
— chromate coatings that are free from any supplementary coatings, such as oil, water or solventbased
polymers or wax.

This document specifies how the symbolic representation of thermally sprayed coatings is indicated on
drawings.

This document specifies procedures for the removal of corrosion products formed on metal and alloy corrosion test specimens during their exposure in corrosive environments. For the purpose of this document, the term “metals” refers to pure metals and alloys.
The specified procedures are designed to remove all corrosion products without significant removal of base metal. This allows an accurate determination of the mass loss of the metal, which occurred during exposure to the corrosive environment.
In some cases, these procedures are also applicable to metal coatings, providing the possible effects from the substrate are considered.

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 a procedure for carrying out impressed current electrochemical chloride extraction from chloride bearing concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement and/or post-tensioned tendon ducts embedded in concrete. In the latter case, it is essential to verify that there is no risk of hydrogen embrittlement, if necessary by conducting trials and installing monitoring during the treatment.
This document does not apply to concrete containing pre-stressing steel which can suffer hydrogen embrittlement during chloride extraction, or to concrete containing epoxy-coated or galvanized reinforcement.
In case of post-tensioned, pre-stressing concrete, the endangered tendon strands may be shielded by the tendon ducts from unwanted and/ or exceeded polarization into the cathodic range and respective water reduction.

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.

This document gives guidelines for the selection of procedures that can be used in the identification
and examination of corrosion pits and in the evaluation of pitting corrosion and pit growth rate.

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.

indoor corrosivity.
The selection of a method for the determination of corrosion attack, description of standard specimens,
exposure conditions and evaluation are given in ISO 11844-2. The measurement of environmental
parameters affecting indoor corrosivity is given in ISO 11844-3.

This document specifies methods for determining corrosion rates with standard specimens of metals
in indoor atmospheres with low corrosivity. For this direct method of evaluation corrosivity, different
sensitive methods can be applied using standard specimens of the following metals: copper, silver, zinc,
steel and lead. The values obtained from the measurements are used as classification criteria for the
determination of indoor atmospheric corrosivity.

This document specifies procedures for designing, preparing and using reversed U-bend (RUB) test
specimens for investigating the susceptibility of the metal to stress corrosion cracking. The term
“metal” as used in this document includes alloys.

This document specifies the requirements and recommendations for cathodic protection systems applied to the internal surfaces of metallic tanks, structures, equipment, and piping containing raw or treated seawater or brackish waters, to provide an efficient protection from corrosion.
Cathodic protection inside fresh water systems is excluded from this document. This is covered by EN 12499.
NOTE   EN 12499 covers internal cathodic protection for any kind of waters, including general aspects for seawater; but excluding industrial cooling water systems. This document specifically details applications in seawater and brackish waters.

EN-ISO 8289-1 specifies two low voltage tests for detecting and locating defects that extend to the basis metal in vitreous and porcelain enamel coatings.Method A (electrical) is applicable to the rapid detection and determination of the general location of defects. Method B (optical), based on colour effects, is applicable to the more precise detection of defects and their exact locations. Both methods are commonly applied to flat surfaces. For more intricate shapes, such as undulated and/or corrugated surfaces, ISO 8289-2 is applicable.

This document specifies the quality requirements for apparatus, components, appliances and accessories of glass-lined steel (including semi-crystallized enamel coatings) and glass-lined steel castings used for process plants. It specifies the quality requirements and the tests to be carried out by the manufacturer as well as the actions to be taken to repair defects. It is also applicable to glass-lined pumps, pump components and fittings. It does not apply to glass-lined flanged steel pipes or glass-lined flanged steel fittings. The test methods specified cover checking the enamel, the dimensional accuracy and the performance of apparatus and components.

It does not contain requirements regarding the chemical or physical properties of vitreous and porcelain enamels.

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 the minimum requirements and the functional characteristics of enamel coatings applied by any process, such as wet dipping, wet flow-coating, wet spraying, wet electrostatic spraying, wet electrodeposition or dry-powder electrostatic spraying, to profiled steel heat exchanger panels in regenerative heat exchangers, before and after packing in baskets. For very severe service conditions, or to obtain extended operational life, more stringent limits can be agreed between customer and supplier.

This document specifies the requirements for product quality and product testing of enamelled valves
and pressure pipe fittings for untreated and potable water supply.

This document specifies requirements for the protection of iron and steel surfaces against corrosion by
applying thermal-sprayed metallic coatings of zinc, aluminium or their alloys.
In this document, requirements for the planning of the corrosion protection system and for the
constructive design of the component to be protected are specified, where thermal spraying is intended
to be the process for the deposition of the metallic corrosion protection.
Some field-related basic terms are defined and instructions for corrosion behaviour of the zinc and
aluminium materials under different environment conditions are provided.
Characteristic properties of the coating, e.g. coating thickness, minimum adhesive strength and surface
appearance, are specified and test procedures for thermal-sprayed corrosion protection coatings of
zinc, aluminium or their alloys are determined.
This document is valid for applying thermal-sprayed zinc and aluminium protection coatings against
corrosion in the temperature range between −50 °C to +200 °C, taking into consideration the service
conditions of any sealants used. Heat-resistant protective coatings of aluminium are covered by
ISO 17834 and are not in the scope of this document.
Other corrosion protection processes, e.g. hot-dip galvanizing (galvanic coating), sherardizing,
electroplating or selection and deposition of organic coatings/paints are not in the scope of this
document.
Requirements for the manufacturing of thermal-sprayed coatings are specified in ISO 2063-2.

This document gives guidelines for determining the average surface density over a measured area
of anodic oxide or of 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 for determination of the coating surface
density by instrumental chemical analysis methods.
With the exception of the gravimetric method as described in ISO 3892, this document does not give the
measurement uncertainties of the methods cited.

This document specifies requirements for electroplated coatings of metallic chromium, with or without
undercoats, on ferrous and non-ferrous metals for engineering purposes. The coating designation
provides a means of specifying the thickness of chromium appropriate for typical engineering
applications.

This European Standard specifies a quantitative method for the measurement of adhesion of metallic and related inorganic coatings applied to metallic surfaces.  Typical coatings for which this European Standard applies are copper, nickel, nickel plus chromium, silver, tin, tin-nickel alloys, zinc, gold.  This European Standard does not apply to certain hot dip and spray coatings.

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 international Standard specifies a method for the determination of resistance to stress corrosion cracking (SCC) of magnesium alloys. This International Standard covers the method of sampling, the types of specimens, the loading procedure, the type of environment and the Interpretation of results.
This International Standard is aimed at the determination of the resistance to SCC as a function of the chemical composition, the method of manufacture and heat treatment of magnesium alloys. This International Standard applies to cast and wrought magnesium alloys in the form of castings, semi-finished products, parts and weldments.
Since most natural and many artificial environments contain chlorides, this International Standard can be used to compare the performance of products employed in environments containing chlorides providing that the failure mechanism is not changed. However, the results of this test should not be considered as an absolute criterion for the quality of alloys.

Important principles indicated in this European Standard should be taken into consideration when surfaces of metallic parts are to be prepared for thermal spraying. This European Standard applies for production of new parts as well as for the repair of worn parts.
This European Standard does not apply for thermal spraying in the case of protection against atmospheric corrosion by coatings of zinc and/or aluminium and their alloys, for which prEN ISO 2063 1:2014 and prEN ISO 2063 2:2014 apply.

This European Standard specifies requirements for the acceptance inspection of thermal spraying equipment, in this case the pressurized part only for low pressure and controlled atmosphere plasma spraying, used in spray jobs to produce thermally sprayed coatings of reproducible quality.
This part should be used in conjunction with EN 1395-1, which includes general requirements and explanations of procedures.
The plasma spraying system itself should be acceptance inspected according to EN 1395-4.

The thermal spray procedure specification (TSPS) is a critically important quality assurance document in the production workflow when producing a thermally sprayed coating.
This European standard defines the minimum requirements that should be followed for the content of a thermal spray procedure specification. When applying the thermal spray procedure specification, the requirements of the coating specification should be met. To ensure traceability, the thermal spray procedure specification should be documented and component-related.
Tests and test scopes should be defined by the manufacturer of the coating in a separate test plan according to the requirements of the coating specification.

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
“wet” conditions.
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,
— metallic coatings (cathodic),
— anodic oxide coatings, and
— organic coatings on metallic materials.
Method B is applicable to
— steel coated with anodic coatings, and
— steel coated with anodic coatings covered with conversion coatings.

This document specifies procedural instructions for qualification testing of thermal sprayers. It defines
requirements, ranges of qualification, test conditions, acceptance requirements and certification for

— to sheet, strip or wire in the non-fabricated form,
— to close-coiled springs, or
— for purposes other than protective or decorative.
This document does not specify requirements for the surface condition of the basis metal prior to
electroplating with zinc. However, defects in the surface of the basis metal can adversely affect the
appearance and performance of the coating.
The coating thickness that can be applied to threaded components can be limited by dimensional
requirements, including class or fit.

This document specifies a method for assessing the corrosion resistance of metals by an alternate
immersion test in salt solution, with or without applied stress.
The test is particularly suitable for quality control during the manufacture of metals including
aluminium alloys and ferrous materials, and also for assessment purposes during alloy development.
Depending upon the chemical composition of the test solution, the test can be used to simulate the
corrosive effects of marine splash zones, de-icing fluids and acid salt environments.
The term “metal” as used in this document includes metallic materials with or without corrosion
protection.
This document is applicable to
— metals and their alloys,
— certain metallic coatings (anodic and cathodic with respect to the substrate),
— certain conversion coatings,
— certain anodic oxide coating, and
— organic coatings on metals.

This document specifies methods of checking the adhesion of electrodeposited and chemically
deposited coatings. It is limited to tests of a qualitative nature.
This document does not describe certain tests that have been developed at various times to give a
quantitative measure of adhesion of metallic coating to a substrate, since such tests require special
apparatus and considerable skill in their performance which renders them unsuitable as quality control
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.
