The dry-ilm thickness is obtained by using the appropriate correction value applied to readings based on adjustment on a smooth, lat steel surface.
Acceptance criteria: ISO 19840 and coating system
Protective paint systems ISOPaints and varnishes — Corrosion protection of steel structures by protective paint systems — Part 6: ISO and coating system data sheet. Pre-coated test plates 5. Schedule of clearing works shall be made in such a way to make possible to start painting as soon as possible while surface has not become soiled again.
Appendix Coating system no. On blast- cleaned surfaces such a procedure will introduce errors. The procedures for areas requiring special consideration, such as welds, edges, corners, ixtures, areas with observed defects, shall be agreed by the interested parties.
In this method, no correction value is used. A2 Name of owner: The objective of this International Standard is to achieve uniformity of practice for measuring the dry-ilm thickness of a coating on a roughened surface. 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. They measure the magnetic ield strength produced by eddy currents caused by the probe in a conductive substrate. ISO and coating system advertisement.
During application of anticorrosive coatings only accepted by painting system 7 paints and solvents should be applied. This example is also applicable when using the methods described in Annexes A and B. Instruments using the eddy current principle can be used but their use is normally on non-ferrous metal surfaces. A4 Paint manufacturer s: Preparation grades of welds, edges and other areas with surface imperfections  ISOPreparation of steel substrates before application of paints and related products — Visual assessment of surface cleanliness — Part 4: If the acceptance criteria above are not met, the inspection area shall ftee rejected see also ISO series.

In this case, the correction value shall be determined in accordance with Annex D. Manufacturers of gauges will quote parameters such as minimum substrate thickness and minimum sample diameter. Rust grades and preparation grades of uncoated steel substrates and of steel substrates after overall removal of previous frre.
Science Chemistry Materials Science Acceptance criteria: Log In Sign Up. Adjust the scale reading to the value of the shim.
This equipment may incorporate a statistical capability. Number of measurements to be taken in accordance with ISO gree The informative appendix to the part 1: It is good practice to identify critical areas of the structure that are affected by welding, cutting, bending and other processes which change the shape, thickness, magnetic properties due to work hardening, heat treatment, etc.
Extreme temperatures can affect instrument performance. If a coating is applied to a roughened steel substrate, the measurement of its dry-ilm thickness is more complicated than for smooth surfaces.
Acceptance criteria: ISO and coating system
This International Standard also speciies criteria which are used with regard to acceptance or non-acceptance of ilm thickness values. Development of speciications for new work and maintenance 3 Terms and deinitions For the purposes of this document, the following terms and deinitions apply.
Documents connected with procedure ISO Preparation of steel substrates before application of paints and related products — Visual assessment of surface cleanliness — Part 1: For the measurement, a sampling plan is laid down as well as an appropriate correction value.
Representative photographic examples of the change of appearance imparted to steel when blast-cleaned with different abrasives ISO NOTE Other methods using a similar principle are available.
Inspection test for visual examination of coating shall be done after curing and on coated parts for every coat. Calibration, on the other hand, is the process of setting and recording the thickness values displayed on a dry-ilm thickness gauge to known values of thickness across the range of the gauge.
