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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

INTERNATIONAL STANDARD ISO 15549:2008(E)
Non-destructive testing — Eddy current testing — General
principles
1Scope
This International Standard defines the general principles to be applied to non-destructive eddy current
examination of products and materials in order to ensure defined and repeatable performance.
It includes guidelines for the preparation of application documents which describe the specific requirements for
the application of the eddy current method to a particular type of product.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.
ISO 9712, Non-destructive testing — Qualification and certification of personnel
ISO 12718, Non-destructive testing — Eddy current testing — Terminology
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 12718 apply.
4 General principles
The eddy current examination is based upon the induction of an electric current in a conducting material. The
quantity measured and analysed is related to the distribution of the induced currents. For alternating excitation,
it is represented by a vector in the complex plane.
The distribution of eddy currents in a material according to depth is governed by physical laws, the density of the
currents decreasing drastically with increasing depth. For high-frequency excitation, this decrease is an
exponential function of depth.
The following properties, alone or in combination, of the product to be tested influence the measured quantity:
— the conductivity of the material;
— the magnetic permeability of the material;
— the size and geometry of the product to be tested;
— the geometrical relationship between the eddy current probe and the product to be tested.
More detailed information is obtained when the measured quantity is displayed in the complex plane.

ISO 15549:2008(E)
The following characteristics of the method represent advantages:
— the method does not involve any physical contact with the product;
— it does not need a coupling medium such as water;
— high throughput speeds can be used.
5 Qualification of personnel
It is assumed that the eddy current testing will be performed by qualified and capable personnel. In order to
ensure that this is the case, it is recommended that personnel be certified in accordance with ISO 9712 or
equivalent.
6 Purpose of examination and products to be tested
The purpose of the examination can be one or more of the following:
— to reveal discontinuities in the product which could affect its fitness for purpose;
— to measure the thickness of coatings or layers;
— to measure other geometric characteristics;
— to measure metallurgical or mechanical properties of the product;
— to measure the conductivity and/or permeability of the product;
— to sort products on the basis of any of the above-mentioned properties.
Examples of products to be tested are conducting materials such as:
— tubes, profiles, bars or wire rods;
— components in the automotive and machining industries;
— forged or cast products;
— multi-layer components in the aircraft industry.
Examples of the application of the method include:
— on-line testing in rolling mills, finishing lines or drawing lines;
— in-service inspection of heat-exchanger tubing;
— verification of the properties of mass-produced articles and semi-finished products;
— maintenance inspection of aircraft;
— inspection of the surfaces of cylindrical holes formed in products.
7 Measurement techniques
Measurements can be static or dynamic, the latter requiring relative movement between the probe and the
product to be tested.
Scanning of the product to be tested can be performed manually or by the use of mechanized equipment which
precisely controls the scan path.
Commonly used measurement techniques are:
a) Absolute measurement.
The measurement of the deviation from a fixed reference point. The reference point is defined by a
calibration procedure and can be generated by a reference voltage or coil. This technique can be used for

ISO 15549:2008(E)
sorting a product into classes based on physical properties (such as hardness), dimensions or chemical
composition. It can also be used for the identification of continuous or gradually changing discontinuities.
b) Comparative measurement.
The subtraction of two measurements, one of which
