Bolts, nuts, caps, sticky tape, fabric, tarpaulin, rubber can be suitable protection. The procedures for areas requiring special consideration, such as welds, edges, corners, ixtures, areas with observed defects, shall be agreed by the interested parties. Blasting Blast clearing to free executed in specially equipped chamber.

Repairadditional coats or recoating as appropriate. In this method, no correction value is used. Passes, curtaining, overflows and drops should fref avoided. Pre qualification Page 8 of 9 2. One shim should be thinner and one thicker than the NDFT of the coat s on the measurement object.
They measure the magnetic ield strength between a permanent magnet and a magnetic substrate. Place the thinner shim on the unpainted surface and the probe on the shim. 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.
Individual reading Correction value used Resulting individual Individual dry-film see Table 2 of dry-film thickness thicknesses outside of ISO This equipment may incorporate a statistical capability. In many instances, the effect of these changes will be small compared to the effect of the blast-cleaned surface inish which is dealt with in the main body of this International Standard.
Acceptance criteria: ISO and coating system
ISO Preparation of steel substrates before application of paints and related products — Surface roughness characteristics of blast-cleaned steel izo ISO Preparation of steel substrates before application of paints and related products – Surface preparation methods — Part 2: This operation is necessary for reception of a design thickness of a covering on all sites of a design.
Design considerations ISOPaints and varnishes — Corrosion protection of steel structures by protective paint systems — Part 4: For guidance, test areas within 15 mm of edges, welds, holes, etc. ISO and coating system advertisement. Instruments as described in 5. A2 Name of owner: Workplaces should be accessible for 119840 of safety data sheets of applied paints by personnel.
The mean value of the four readings taken should be determined and represents the dry-ilm thickness at the particular spot. For some instruments, setting to zero is required with the probe on the prepared but uncoated 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: Roughened steel substrates include those prepared by abrasive blast- cleaning or abrading. ISOPaints and varnishes — Determination of ilm thickness ISOPreparation of steel substrates before application of paints and related products isp Surface roughness characteristics of blast-cleaned steel substrates — Part 1: They measure the force required to overcome the magnetic attraction between a magnet and a magnetic substrate.
Care needs to be taken on weld material, on areas at or close to the edges of the substrate, oso at or close to bends as, depending on the speciic design of the coating thickness gauge, the effect will be most noticeable in these frde.
Prior to start painting works responsible for these works person should check and consider all the possible ambiguities. Work conforms to the requirements? International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
is Science Chemistry Materials Science Acceptance criteria: Number of measurements to be taken in accordance with ISO Condition of the cleared surface is expressed by degree of preparatory treatment and regulated by standard ISO This International Standard also speciies criteria which are used with regard to acceptance or non-acceptance of ilm thickness values.
A4 Paint manufacturer s: 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.
Each coat layer shall be applied uniformly over the whole surface.
