It is good practice rfee 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. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. 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.

For some instruments, setting to zero is required with the probe on the prepared but uncoated ieo. Rust grades and preparation grades of uncoated steel substrates and of steel frer after overall removal of previous coatings.

Each coat layer shall be applied uniformly over the whole surface. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. For the measurement, a sampling plan is laid down as well as an appropriate correction value. Preparation grades of welds, edges and other areas with surface imperfections [4] ISOPreparation of steel substrates before application of paints and related products — Visual assessment of surface cleanliness — Part 4: This force is related to the coating thickness.

Qualification of personnel Workers executing anticorrosive painting should have required professional qualification and pass corresponding training with certified acknowledgement. Enter the email address you signed up with and we’ll email you a reset link. Applied personal protection equipment Frer, paragraph 3; Clause 1, paragraph 2; 6. Page 3 of 9 Acceptance criteria: Work conforms to the requirements? Any arisen soiling should be immediately removed and damaged layer 198840 be restored.


Acceptance criteria: ISO 19840 and coating system

Protective paint systems ISO iao, Paints and varnishes — Corrosion protection of steel structures by protective paint systems — Part 6: The procedures for areas requiring special consideration, such as welds, edges, corners, ixtures, areas with observed defects, shall be agreed by the interested parties.

For more details, see Annex C. Measurements taken on a coating on a roughened steel substrate will therefore be higher than the tree value above the peaks of the proile.

Degree of the surface preparatory treatment of products should correspond to requirements of specification Sa3 — blast cleaning to pure metall. The procedure described in this International Standard is based on the use of instruments of the permanent magnet, electromagnet and eddy current type.

Rotary Wheel Heat Exchangers. Workplaces should be accessible for inspection of safety data sheets of applied paints by personnel. ISO shall not be held responsible for identifying any or all such patent rights. If the number of readings is not speciied in the contract or speciication, ive individual readings see 3.

Preparation grades of previously coated steel substrates after localized removal of previous coatings [3] ISOPreparation of steel substrates before application of paints and related products — Visual assessment of surface cleanliness — Part 3: NOTE Adjustment is carried out by the user in most cases.

Individual reading Correction value used Resulting individual Individual dry-film see Table 2 of dry-film thickness thicknesses outside of ISO The thickness of the dry ilm above the peaks of the proile is deined as the instrument reading minus an appropriate correction value.

This new measurement will then be the individual dry-ilm thickness. On blast- cleaned surfaces such a procedure will introduce errors.

Content of procedure 3.

This enables the minimum, maximum, mean and standard deviation to be calculated. PowerPoint Presentation – Joan Miro. If this is not in accordance with 6. The chosen methods entail the measurement of dry-ilm thickness using measurement instruments based on the permanent magnet principle and the inductive magnet principle.


Isi conditions Whenever possible, blasting and application of anticorrosive coatings should be executed in the adapted for such works facilities workshops.

Inspection should be done for ever y parts. The irst value shall then be rejected and replaced by the result of the repeated measurement. 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: Click here to sign up.

Manufacturers of gauges will quote parameters such as minimum substrate thickness and minimum sample free. Safety of work As many paints especially diluted with solvent contain unhealthy substances, it is necessary to observe the established norms and safety rules. This second edition cancels and replaces the irst edition ISO Purpose of procedure The procedure CP-S7 is a guide upon performance of paint works in accordance with Coating system no.

It is necessary visually to compare a profile of blasted surface with reference sample. Freee performance test methods ISOPaints and varnishes — Corrosion protection of steel structures by protective paint systems — Part 7: A5 Corrosion protection work carried out by: B2 Surface profile roughnessISO Pre qualification Page 8 of 9 2.

Shall be done on every parts. Conditions air, surface temperature, humidity, paint temperature at fulfillment of preparatory treatment, painting works and drying of paint should not deviate from technical requirements indicated in the specifications for corresponding paints.

Schedule of clearing works shall be made iwo such a way to make possible to start painting as soon as possible while surface has not become soiled again.
