Acceptance criteria: ISO 19840 and coating system

They measure the magnetic ield strength between a permanent magnet and a magnetic substrate. Norsok standard Frde, Edition 6, Surface preparation and protective coating Page 6 of 9 7.

NOTE 2 For deviating surface proiles or in the case of particular agreements between the interested parties, a method for determining the correction value to be used is given in Annex D. They produce a coating thickness measurement by measuring the change in magnetic ield strength within their probes due to the proximity of the magnetic substrate.

Safety of work As many paints especially diluted with solvent contain unhealthy substances, it is necessary to observe the established norms and safety rules.

These instruments are mainly used to measure the thickness of coatings on non-magnetic i. If speciied or agreed, the standard can also be used for other applications. fres

Execution and supervision of paint work ISOPaints and varnishes — Corrosion protection of steel structures by protective paint systems — Part 8: Calibration is carried out by the gauge manufacturer using traceable thickness standards in most cases. ISOPaints and varnishes — Determination of ilm thickness ISOPreparation of steel substrates before application of paints and related products — Surface roughness characteristics of blast-cleaned steel substrates — Part 1: Instruments using the eddy current principle can be used but their use is normally on non-ferrous metal surfaces.

Environment conditions Whenever possible, blasting and application of anticorrosive coatings should be executed in the adapted for such works facilities workshops. Since such adjustment is more representative of the isk, the reading variations will diminish.

They measure the force required to overcome the magnetic attraction between a magnet and a magnetic substrate. Number of measurements to be taken in accordance with ISO isl They can only be adjusted at one particular point on the scale, and this adjustment will have a limited effect on calibration over the full range.

In case of paints are stored in a cold premise, it is necessary to place them before usage for a while in warm that they were adequately warmed. The methods in Annexes A and B are intended to be used only if speciied or agreed. Degree of the surface preparatory treatment of products should correspond to requirements of specification Sa3 — blast cleaning to pure metall. Connecting data records on quality 1. This enables the minimum, maximum, mean and standard deviation to be calculated.

The dry-ilm thickness is obtained by using the appropriate correction value applied to readings based on adjustment on a smooth, lat steel surface.

The thickness of the dry ilm above the peaks of the proile is deined as the instrument reading minus an appropriate iao value. ISO shall not be held responsible for identifying any or all such patent rights.

Check an intermediate-value shim to ensure that the adjustment is correct. Click here to sign up.

This new measurement will then be the individual dry-ilm thickness. Science Chemistry Materials Science Acceptance criteria: Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

Content of procedure 3. The effect of surface roughness on the measurement result increases with proile depth, but the result will also depend on the design uso the measurement probe and the thickness of the coating.

Acceptance criteria: ISO and coating system

ftee If a correction value is used, it shall be subtracted from the individual reading to give the individual dry-ilm thickness in micrometres. At a substrate thickness of above approximately 5 mm, the effect is generally insigniicant. Waste should be collected and utilized according to the valid legislation and the established rules.

For the measurement, a sampling plan is laid down as well as an appropriate correction value. The main task of technical committees is to prepare International Standards. Annex B describes a method for multiple isl. In this case, the arithmetic mean value of the four readings is used in place of an individual reading. Soiling of the painted surfaces between layers is inadmissible.
