А Префаце
ИСО (international organization for standardization) is the national standards bodies (ISO member) of the alliance. Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака институција чланица заинтересована за предмет за који је основан технички комитет има право да буде заступљена у комитету. У овај посао су укључене и владине и невладине међународне организације које су у вези са организацијама за стандардизацију. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електричне стандардизације.

ИСО 2360-2017 “Non-conductive coatings on non-magnetic conductive substrates – Measurement of coating thickness – Amplitude sensitive eddy current method”

1 Обим
This document specifies a sensitive eddy current instrument using amplitude of nonmagnetic conductive non conductive coating thickness on the base metal nondestructive measurement method.

In this document, the term “coating” is used for materials such as paints and varnishing, electroplating coatings, enamel coatings, plastic coatings, overlays and powder coatings. The method is particularly suitable for thickness measurements of most oxide coatings produced by anodic oxidation, but not for all transformed coatings, some of which are too thin to be measured by this method (see article 6).

The method also can be used to measure the conductive nonmagnetic metal coating on the substrate. Међутим, the phase-sensitive eddy current method specified in ISO 21968 is particularly suitable for this application and can provide higher accuracy thickness results (see Annex A).

The method is not suitable for measuring non-magnetic metal coatings on conductive base metals. In accordance with the ISO 21968 phase-sensitive eddy current method is particularly useful for this application. Међутим, in the special case of very thin coatings with very small electrical conductivity, the amplitude sensitive eddy current method can also be used for this application (see Appendix A).

Although this method can be used to measure coating thickness on magnetic base metals, it is not recommended for this application. In this case, the magnetic method specified in ISO 2178 can be used. Only about 1 mm above the very thick coating, the amplitude of sensitive eddy current method can also be used for this application (see appendix A).

3.1 the adjustment of the measuring system

A set of operations performed on a measuring system so that it provides a prescribed indication corresponding to a given value of the quantity to be measured

Белешка 1: the adjustment of the measuring system can include a zero point adjustment, migration and range adjustment (sometimes called gain adjustment).

Белешка 2: Adjustment of a measurement system should not be confused with calibration, which is a prerequisite for adjustment.

Белешка 3: after adjustment measurement system, usually need to recalibrate measurement system.

Белешка 4: in popular culture, the term “calibration” is often mistakenly used, rather than the term “adjust”. Similarly, the terms “verification” и “инспекција” are often used in place of the correct term “calibration”.

3.2 Калибрација

Under the specified conditions, the first step in the measurement uncertainty in measurement standards provide the number of values and the related measurement uncertainty of the corresponding relationships between instructions operation, and in the second step USES this information, so that measurement results from instructions

ИСО 2360-2017 “Non-conductive coatings on non-magnetic conductive substrates – Measurement of coating thickness – Amplitude sensitive eddy current method”

Белешка 1: Calibration can be expressed in terms of sentences, calibration functions, calibration graphs, calibration curves or calibration tables. In some cases, it may include an additive or multiplicative correction for an indication with associated measurement uncertainty.

Белешка 2: Calibration should not be confused with the adjustment of the measurement system (often erroneously referred to as “self-calibration”), nor with calibration verification.

Remark 3: Typically, the first step in the above definition is itself considered calibration.
