Connecting data records on quality Content of procedure 3. Appendix Coating system no. If the acceptance criteria above are not met, the inspection area shall be rejected see also ISO series.
The mean value of the four readings taken should kso determined and represents the dry-ilm thickness at the particular spot. The dry-ilm thickness is obtained by using the appropriate correction value applied to readings based on adjustment on a smooth, lat steel surface.

Rotary Wheel Heat Exchangers. Repair of defects 3. Help Center Find new research papers in: Before application dree each coat layer a strip painting with brash or roller of all the welded seams, internal and external corners, edges, and areas which cannot be completely covered by airless spraying method should be executed.
Annex A, which is informative, is a method based on adjusting the instrument to known thicknesses on a rough surface. Jso an intermediate-value shim to ensure that the adjustment is correct.
Acceptance criteria: ISO 19840 and coating system
Since such adjustment is more representative of the surface, the reading variations will diminish. Calibration is carried out by the gauge manufacturer using traceable thickness rree in most cases. The instrument is ixo ready for use. If this is not possible, a special adjustment sample can be provided which is, in its material properties that can affect the ilm thickness measurement, similar to the steel structure and has been cleaned and pre-treated in the same way.
The methods in Annexes A and B are intended to be used only if speciied or agreed. When, during a series of measurements, an individual dry-ilm ieo value does not meet a criterion [see 9 b and d ], a repeated measurement not more than 10 mm from fdee point of the irst measurement shall be carried out.
Page 3 of 9 Acceptance criteria: ISO and coating system advertisement. The criteria deined above include all measurement uncertainties for example instrument accuracy, operator skillprovided that the requirements of this International Standard have been met.
Number of measurements to be taken in accordance with ISO 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: Calibration certificates should be accessible for review. They measure the magnetic ield strength between a permanent magnet and a magnetic substrate. The informative appendix to the part 1: The magnetic ield strength is related to the coating thickness.

Environment conditions Whenever possible, blasting and application of anticorrosive coatings should be executed in the adapted for such works facilities workshops. A4 Paint manufacturer s: Log In Sign Up. 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.
Preparation and lso in premises provide optimum conditions for the achievement of best result.
Particular attention should be paid to the following: Inspection test for visual examination of coating shall be done after curing 19480 on coated parts for every coat.
The measurement instruments used are adjusted. This equipment isl incorporate a statistical capability. If a sample showing the surface proile is available and the proile is not in accordance with ISOthe correction value shall be determined in accordance with Annex D. During application of anticorrosive coatings only accepted by painting system 7 paints and solvents should be applied.
In this case, the correction value shall be determined in accordance with Annex D. For more details, see Annex C. Norsok standard M, Edition 6, Surface preparation and protective coating Page 6 of 9 7. In frwe case, the arithmetic mean value of the four readings is used in place of an individual reading.
Documents connected with procedure ISO Preparation of steel substrates before application of paints and related products — Visual assessment of surface cleanliness — Part 1: Readings taken in this way should be rree separately, together with the test results. Nominal specified dry-film thickness: When using this method, the following details of this International Standard do not apply:
