CEN/TC 262/WG 2 - Hot dip galvanized coatings

This document specifies spectroscopic ellipsometry for the determination of optical properties (refractive index n and extinction coefficient k) and the optical classification of different types of amorphous carbon films within the n-k plane.
It is applicable to amorphous carbon films deposited by ionized evaporation, sputtering, arc deposition, plasma-assisted chemical vapour deposition, hot filament techniques and others.
It does not apply to carbon films modified with metals or silicon, amorphous carbon films that have a gradient of composition/property in the thickness, paints and varnishes.

ISO 14708-3:2017 provides guidelines and recommendations regarding the general principles of design that are appropriate for articles to be sherardized for corrosion protection.
The protection afforded by the sherardized coating to the article will depend upon the method of application of the coating, the design of the article and the specific environment to which the article is exposed. The sherardized article can be further protected by application of additional coatings (outside the scope of this document), such as organic coatings (wet paints or powder coatings). When applied to sherardized articles, this combination of coatings is often known as a "duplex system".
General guidance on this subject can be found in ISO 12944‑5 and EN 13438.
The maintenance of corrosion protection in service for steel with sherardized coatings is outside the scope of this document.
Specific product-related requirements (e.g. for sherardized coatings on fasteners or tubes, etc.) will take precedence over these general recommendations.

ISO 6509-1:2014 specifies a method for the determination of dezincification depth of copper alloys with zinc exposed to fresh, saline waters or drinking water. The method is intended for copper alloys with a mass fraction of zinc more than 15 %.
ISO 6509-1:2014 describes only the test methodology and does not set out criteria for acceptability of materials for a specific application. Acceptance criteria are described in ISO 6509‑2.

ISO 7539-1:2012 describes the general considerations that apply when designing and conducting tests to assess susceptibility of metals to stress corrosion.
ISO 7539-1:2012 also gives some general guidance on the selection of test methods.

Includes four methods: iron(III) sulfate - sulfuric acid test, copper - copper-sulfate - sulfuric acid test, hydrochloric acid test and nitric acid test. ISO 9400 defines the term nickel-based alloy. Specifies apparatus, test specimens, procedure and evaluation.

Covers procedures for designing, preparing and using uniaxially loaded tension specimens. These specimens may be used to test a variety of product forms (for example sheet, plate, tubes, wire or rod as well as parts joined by welding, riveting, or other methods). Uniaxially loaded tensile specimens may be stressed quantitatively with equipment for application of either a constant load, a constant strain or an increasing load or strain.

Covers procedures for designing, preparing, stressing, exposing and inspecting C-ring specimens. These versatile, economical specimens may be used to test a variety of product forms including parts joined by welding. C-ring specimens may be stressed to predeterminded levels, using simple equipment for application of either constant load or constant strain.

Covers procedures for designing, preparing and using bent-beam test specimens. These specimens may be used to test a variety of product forms (i. e. sheet, plate, flat extruded material, wire or rod). They are espesially suitable for multiple testing and for atmospheric stress corrosion tests; they are usually tested under nominally constant strain conditions. Bent-beam specimens made from high strength materials may fracture rapidly and can be dangerous.

Covers procedures for designing, preparing and using U-bend test specimens. These specimens may be used to test a variety of product forms (for example sheet, plate, flat extruded material, wire or rod). The principal acvantages of the U-bend test are its simplicity and its adaptability for use in plants. A disadvantage is that stesses cannot be quantified with accuracy. U-bend specimens made from high strength materials may fracture rapidly and can be dangerous.

Specifies specimens, apparatus and procedure of corrosion tests. Applies to metals and alloys with and without permanent corrosion protection or temporary corrosion protection. The requirements specified in ISO 7384 are intended for application in other International Standards dealing with corrosion tests in artificial atmospheres as well as in accelerated methods of test and the construction of new chambers.

Der vorliegende Teil von ISO 6509 legt die Akzeptanzkriterien für die Wahl von entzinkungsbeständigen Kupfer-Legierungen mit einem Massenanteil an Zink von mehr als 15 % fest, die Frischwasser, chloridhaltigen Wässern oder Trinkwasser ausgesetzt werden. Die Akzeptanzkriterien basieren auf den Auslagerungsprüfungen in ISO 6509-1.
Die geprüften und akzeptierten Werkstoffe können in Form eines Halbzeuges oder in Form eines fertigen Produkts (Armatur, Ventil usw.) vorliegen.
Diese Norm gilt nicht für komplexe Produkte, wie z. B. Durchflussmesser oder Pumpenteile. Weiterhin können weitere Eigenschaften des Werkstoffs für die vorgesehene Anwendung zu berücksichtigen sein. Diese Norm ist nicht für die Bewertung der Entzinkung im Fall von Schadensfällen in der Anwendung vorgesehen.

TC - Missed to inform CCMC that also Part 3 supersedes EN ISO 14713:1999 and not only Parts 1 and 2 (E and F versions)

ISO 14713-3:2009 provides guidelines and recommendations regarding the general principles of design that are appropriate for articles to be sherardized for corrosion protection.
The protection afforded by the sherardized coating to the article will depend upon the method of application of the coating, the design of the article and the specific environment to which the article is exposed. The sherardized article can be further protected by application of additional coatings (outside the scope of ISO 14713-3:2009), such as organic coatings (wet paints or powder coatings). When applied to sherardized articles, this combination of coatings is often known as a “duplex system”.
General guidance on this subject can be found in ISO 12944-5 and EN 13438.
The maintenance of corrosion protection in service for steel with sherardized coatings is outside the scope of ISO 14713-3:2009.
Specific product-related requirements (e.g. for sherardized coatings on fasteners or tubes, etc.) will take precedence over these general recommendations.

Applies to metals and alloys, and metals and alloys with metallic and non-metallic non-organic coatings. The methods are intended for the determination of the amount and type of corrosion effect, arising in natural atmospheres, caused by contact with different metals (coated metals), and for the evaluation of the effectiveness of bimetallic corrosion protection treatments.

The method applies to brass exposed to frech or saline waters. May be used for control or research purposes, but the field of application is not specified. The method consists of exposure of test pieces to copper(II) chloride solution followed by microscopic examination.

Descsribes the general considerations which apply when designing and conducting tests to assess susceptibility of metals to stress corrosion. Particular methods of test are not treated in detail in this document. These are specified in the additional parts of ISO 7539.

Describes requirements for test specimens, test sites and their characterization, operating conditions, test procedures and the test report.

This European Standard constitutes guidelines containing general recommendations on the corrosion protection of iron and steel structures, including connections, by zinc or aluminium coatings. Particular reference is made to hot dip coating and thermal spraying on hot-rolled steel or cold-formed steel but these recommendations also apply to other zinc coatings (electroplating, mechanical coating, sherardizing, etc.).

This standard specifies the general properties of and methods of test for coatings applied by hot dipping in zinc (containing not more than 2 % of other metals) on fabricated iron and steel articles. It does not apply to: a) sheet and wire that are continuously hot dip galvanized; b) tube and pipe that is hot dip galvanized in automatic plants; c) hot dip galvanized products for which specific standards exist and which may include additional requirements or requirements different from those of this European Standard.
