ISO/FDIS 2361

Electrodeposited nickel coatings on magnetic and non-magnetic substrates — Measurement of coating thickness — Magnetic method

This second edition cancels and replaces the first edition (i. e. ISO 2361:1972). Specifies the method of using coating thickness instruments of the magnetic type ror non-destructive measurements of the thickness. The method may nkot be applicable to autocatalytic (electroless) nickel coatings. For the purpose of this Standasd, two types of nickel coating are disringuished: coatings on magnetic substrates and on non-magnetic substrates.

Revêtements électrolytiques de nickel sur substrat magnétique et non magnétique — Mesurage de l’épaisseur du revêtement — Méthode magnétique

La présente Norme internationale spécifie une méthode magnétique de mesurage non destructif de l'épaisseur des revêtements électrolytiques de nickel sur métal de base magnétique ou non magnétique. Cette méthode ne s'applique pas aux revêtements autocatalytiques de nickel (nickel chimique), du fait de leur composition chimique. La présente Norme internationale concerne deux types de dépôts de nickel, à savoir : a) revêtements de nickel sur métal de base magnétique (revêtements de type A); b) revêtements de nickel sur métal de base non-magnétique (revêtements de type B). Tous les instruments peuvent être utilisés sur les deux types de revêtements. Les instruments basés sur le principe de l'attraction magnétique ont une plage de mesurage efficace allant jusqu'à 50 µm dans le cas de revêtements de type A, et allant jusqu'à 25 µm pour les revêtements de type B. Les instruments de mesurage par réluctance ont une plage de mesurage bien supérieure, permettant des mesurages jusqu’à 1 mm et plus sur les deux types de revêtements.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings, in
collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 262,
Metallic and other inorganic coatings, including for corrosion protection and corrosion testing of metals and
alloys, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 2361:1982), which has been technically
revised.
The main changes are as follows:
— the nickel measuring methods were split into Type A, Type B and Type A and B;
— common measurement ranges were added for every method;
— subclauses on the factors that influence the measurement uncertainty were added;
— restructured and split into clauses and subclauses;
— Clause 9 on the test report was added;
— editorial changes were made.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
