5.3 Documents 5.3.1 Information for the coater Specific information on the coating materials will be given in the manufacturer’s product data sheets. An indication of the minimum amount of information required for a product data sheet is indicated in the chapter on the different coating materials. 5.3.2 Test certificate for the coating In case inspection operations are carried out as agreed by the purchaser and the coater at the time of enquiry and order, the inspection documents shall be according to EN 10204. 6 Application of the coating and general requirements 6.1 Preparation of the surface before coating 6.1.1 General Surface preparation shall be carried out in accordance with the recommendations of the manufacturer. SIST EN 10329:2006
EN 10329:2006 (E) 9 6.1.2 Preparation of the steel surface 6.1.2.1 General At the time of application, the surface to be coated shall be dry and free from any contamination (such as earlier coatings, non-adherent particles, grease, oil, salt etc.) that could be detrimental to surface preparation or the adhesion of the coating to the steel. The surface shall be cleaned to remove any greasy substances and salt. Filing or grinding shall be used to remove any weld spots, slag or burrs that could pierce the coating. The preparation of the surface can be made either by brush cleaning or abrasive blast cleaning. 6.1.2.2 Brush cleaning Rust and scale shall be removed, manually or mechanically, using wire brushes or any other suitable method that does not affect the quality of the surface to be coated; all dust and debris produced shall be removed correctly. After brush cleaning, the steel surface shall correspond to grade St 3 as defined in EN ISO 8501-1 or better. The roughness of the cleaned surface shall be specified by the manufacturer and shall be measured using a method given in the coating application and repair procedure. Oxidation and rust are removed by hand or mechanically using rotary steel brushes or any other appropriate means, which do not affect the quality of the part to be coated. The dust created by this operation shall be removed correctly. 6.1.2.3 Abrasive blast cleaning Rust and scale shall be removed by blast cleaning with a suitable abrasive to produce a surface that corresponds to Grade Sa 2½ as defined in EN ISO 8501-1 or better. The roughness of the cleaned surface, and the choice of abrasive, shall be specified by the manufacturer and shall be measured using a method given in the coating application and repair procedure. After abrasive blast cleaning, the steel surface shall be inspected. By agreement with the customer, all slivers, laminations, weld spots or other imperfections exposed by the cleaning that may be detrimental to the quality of the coating shall be removed. After these imperfections have been removed, the residual thickness of the steel shall meet the minimum tolerance requirements of the tube standard. 6.1.2.4 Reconditioning If the joint to be coated becomes contaminated or rusted after surface preparation, this area shall be subjected to further cleaning according to the requirements of this European Standard to give a suitable surface for the application of the coating. 6.1.3 Preparation of the adjoining factory applied coating The factory coating adjacent to the joint area shall also be prepared to provide a suitable surface for the joint coating to adhere to. The methods for preparing this area are given in the clause covering the different joint coating materials. 6.2 Conditions before application The temperature of the joint shall be at least 3 °C above the dew point. Before the coating is applied, all residual abrasive dust and debris shall be removed from the surface of the joint by a method given in the coating application and repair procedure. By agreement with the purchaser, chemical pre-treatment may be used to supplement the surface preparation. SIST EN 10329:2006
EN 10329:2006 (E) 10 Qualified personnel shall apply the coating according to the specified procedure that may have been qualified by the purchaser. The joint shall not be exposed to conditions, such as high temperature, that would cause oxidation of the surface sufficient to be detrimental to the quality and adhesion of the coating. At the time of application, the surface temperature of the joint shall be within the temperature range specified by the manufacturer. The temperature of the joint shall be monitored, using a suitable technique, to ensure that the application conditions on the steel substrate and factory applied coating are being met fully. During bad weather, such as wind and rain, cleaning operations may only be carried out if suitable protective awnings, possibly heated depending on the type of the applied coating are installed. 6.3 Appearance of the coating During the visual inspection, the appearance of the coating applied shall be homogenous across the entire surface, in particular no surface defects detrimental to the quality of the coating (grit, foreign particles, pitting, blisters.) shall be observed. 6.4 Testing During production, there should be regular inspections of surface preparation and coating application; procedures are given in Annex I. 6.5 Additional mechanical protection Additional mechanical protection (e.g. rockshield) is not covered in this European Standard. 6.6 Repair The acceptability of coating repair and the repair procedure is subject to agreement between the purchaser and the coater. 6.7 Qualification of the application procedure and the coater Details of the application procedure and the coating material shall be supplied to the purchaser upon request.
If requested, qualification testing to demonstrate the characteristics of the coating shall be carried out. This test shall use the coating materials, the procedure, equipment and personnel that will be used on site and will take into account specific application conditions found on site; recommendations for the procedure are given in Annex I. 6.8 Preliminary quality inspection The coater shall ensure that: the products comply with the specification; the storage instructions are followed. 7 Coatings 7.1 Bituminous tapes, petrolatum tapes, plastic tapes or heat shrinkable materials 7.1.1 General All coatings made by tapes or heat shrinkable materials shall meet the requirements of EN 12068.

The heat shrinkable materials come in the form of the following: tubular sleeve; wrap around sleeve; pre-formed material (assembly for complex configuration parts). Heat shrinkable materials may be applied with or without primer, depending on the nature of adhesive. 7.1.3 Information for the coater The manufacturer shall supply data sheets giving information on the coating material that meets EN 12068. 7.1.4 Surface preparation Surface preparation shall be carried out according to the provisions of this European Standard and the recommendations of the manufacturer (see the information required from the manufacturer according to
EN 12068). 7.1.5 Application of the coating 7.1.5.1 General Application of the coating shall be carried out in accordance with the recommendations of the manufacturer (see manufacturer’s information, as required in EN 12068). 7.1.5.2 Application of the primer Where applicable application of the primer shall be carried out in accordance with the recommendations of the manufacturer (see manufacturer’s information, as required in EN 12068). For petrolatum tapes normally there is no primer necessary. 7.1.5.3 Application of the tape or the heat shrinkable material Application of the material shall be carried out in accordance with the recommendations of the manufacturer (see manufacturer’s information, as required in EN 12068).
