Introduction

PETROBRAS Technical Standards are prepared by Working Groups - WG

(consisting specialized of Technical Collaborators from Company and its Subsidiaries), are

commented by Company Units and its Subsidiaries, are approved by the Authoring Subcommittees -

SCs (consisting of technicians from the same specialty, representing the various Company Units and

its Subsidiaries), and ratified by the Executive Nucleus (consisting of representatives of the Company

Units and its Subsidiaries). A PETROBRAS Technical Standard is subject to revision at any time by its

Authoring Subcommittee and shall be reviewed every 5 years to be revalidated, revised or cancelled.PETROBRAS Technical Standards are prepared in accordance with PETROBRAS Technical

StandardN-1. For complete information about PETROBRAS Technical Standards see PETROBRAS

Foreword

This Standard is the English version (issued in 11/2012) of PETROBRAS N-13 REV. K 11/2012. In case ofdoubt, the Portuguese version, which is the valid document for all intents and purposes, shall be used.

1 Scope

1.1 This Standard settles the conditions required for application and quality control of paint systemsfor industrial equipment (see PETROBRAS N-2), piping and pipeline systems (see PETROBRASN-442 and N-2843), painting of galvanized surfaces, ferrous and nonferrous alloys, composite andpolymeric materials (see PETROBRAS N-1021), offshore exploration and production units (seePETROBRAS N-1374) steel structures (see PETROBRAS N-1550), vessels (see PETROBRASN-1192), machinery, electrical equipment, and instruments (see PETROBRAS N-1735), painting ofequipment submerged in seawater (see PETROBRAS N-2037), galvanized tower (see PETROBRASN-2441), tanks, spheres and cylinders (see PETROBRAS N-2913).

1.2 This Standard also covers conditions for storage and receiving of paints, thinners and safetyrequirements.

1.3 It is forbidden the use of chromate, sulfates and molybdates based pigments, as well as, thesulfochromate lead and any other substances containing lead and chromate (chromium VI).

1.4 This Standard is to be applied to procedures started from its issue date.

4.8.2 Homogenization shall occur in the original container, and the paint shall not be removed from itbefore all the settled pigment has been incorporated into the vehicle. However, part of the paint notsedimented may be temporarily removed to facilitate the homogenizing process. Should difficultiesarise in the dispersion of the settled pigment, the paint shall not be used. [Recommended Practice]

4.8.3 Mixing and homogenizing shall be carried out by a mechanical mixer, with hand mixing beingallowed for containers with a capacity of up to 3,6 L. Paints pigmented with aluminum shall be

manually mixed. For zinc-rich paints (PETROBRAS N-1277, N-1661, N-1841 and N-2231), mixingshall always be by mechanical means.

6.6.1.5 For the other items covered by this Standard, a number of tests corresponding, in absolutevalue, to 1 % of the total painted area shall be performed. For example:

a) for a painted area of 25 m2

(1 % of 25 is equal to 0,25) at least one adhesion tests shall

be performed;b) for a 300 m2

area (1 % of 300 is equal to 3), at least 3 tests shall be performed, distributeduniformly throughout the entire painted area.

NOTE 1 The referenced criteria is valid when the area is painted using the same batch of paint andthe painting is made at the same day, not being allowed to add the areas in order to quantifythe number of tests.

NOTE 2 When the painting is made using different batches of the same paint and it does not bemade at the same day, the painted areas shall be identified, mapped and inspectionedseparately in accordance with the criterion established in 6.6.1.5.

NOTE 3 The adhesion test shall be made priorately in areas which are considered as critical in thepainted structure, such as the Heat Affected Zone (HAZ), by and also in areas where theaccess is hard, which may have faults in the painting.

6.6.2 Description of Tests

6.6.2.2 Pull-Off Test

6.6.2.2.1 The test shall be performed after total application of the coating and curing time andwhenever the procedure standard of painting system or contractual requirements determine the test.

6.6.2.2.2 The test and results record shall be done based on ASTM D 4541:2009, Method D -Equipment Type IV or ABNT NBR 15877:2010,Annex A.2.

7.5 Adhesion

7.5.1 X Adhesion Test

7.5.1.1 The results of the adhesion test shall be compared with the visual standards ofABNT NBR 11003, in accordance with the criteria described in 7.5.1.2 and 7.5.1.3.

7.5.1.2 For the adhesion test performed by method A (cross-section in X), the qualitative technicalcriteria for acceptance shall be as follows:

7.5.1.2.1 Assessments along the incisions: X1 (maximum) when the primer is rich-zinc, the maximumvalue is X2.

7.5.1.2.2 Assessment on intersection of cross-sections: Y2 (maximum), for any type of paint.

NOTE The result X2 (maximum) is also valid for subsequent coats to rich-zinc primer coat(PETROBRAS N-1277, N-1661, N-1841andN-2231).

7.5.1.3 If a test is rejected it shall be repeated at 2 points located 1 m from the previous test. These 2tests shall not be computed in the criteria set out in 6.6.1.4 e 6.6.1.5.

7.5.1.3.1 If both tests do not show signs of lack of adhesion, repair the paint film on the tested regionsand the test is considered approved.

7.5.1.3.2 If one of the tests shows signs of lack of adhesion, the entire painting corresponding to thatinspection shall be rejected.

7.5.2 Pull-off Test

7.5.2.1 The acceptance criteria for the test are set out in Annex A of this Standard.

Figure 1 - Types of Adhesion Failure

7.5.2.3 If any test is failed, it shall be repeated at 4 diametrically opposite points, spaced 300 mmfrom the local of the failure of the previous test. These 4 tests should not be included on the criteria

described in 6.6.1.4 and 6.6.1.5.

7.5.2.4 If the 4 tests are approved the regions tested shall be repaired and the test is consideredapproved.

NOTE The repair shall be performed in a circular area with a radius of 200 mm, considering eachfailure as the geometric center.

7.5.2.5 If at least one of the four tests is failed, all the painting that corresponds to this inspection shallbe rejected.

7.6 Wet Film Thickness (WFT)

The minimum wet film thickness (WFT) is obtained by dividing the specified dry film thickness (DFT)by the value of the percentage of solids by volume (SV), multiplied by 100 (WFT = (DFT / SV) x 100).Any measurement found below this value shall be immediately corrected.

7.7 Dry Film Thickness (DFT)

7.7.1 No thickness measurement, made according to 6.8.1, shall present a value below the minimumdry film thickness specified in the paint system. Whenever the minimum thickness is found to be

smaller than that specified, the area shall be mapped by means of new measurements and anadditional coat shall then be applied, or a compensation on the next coat, since the paints are of thesame chemical nature and mechanism of corrosion protection. For silicate based zinc-rich paints(PETROBRAS N-1661, N-1841,N-2231), it shall be totally removed for new application.

7.7.2 Areas with an increase of up to 40 % in the thickness per coat specified in the paint system areaccepted. For increases above 40 %, the manufacturer shall be contacted about the possibility ofacceptance. For ethyl silicate-based zinc-rich paints (PETROBRASN-1661 andN-2231), an increaseof up to 20 % in the minimum thickness per coat specified in the paint system is accepted.

7.8 Holidays

7.8.1 The surface examined according to 6.9 shall not present holidays and the region presentingflaws shall be touched up.

7.8.2 The test for determining holidays shall be done with a report showing the mapping of porosities.These porosities shall be touched up and re-test shall be done to verify if the touch-ups weresatisfactory.

8 Safety

8.1 Paint storage areas shall be provided with a fire-fighting system and may not be used to storeanother type of material.
