J-11/N1 2007: Substrate Steelpanels, blast-cleaned to Sa 2½ Resist 86 1 x 75 µm Jotacote Universal Al 1 x 150 µm Hardtop PS5 1 x 60 µm Application details as exact DFT values are given in appendix 4. The ageing test was performed from July 11 th 2007 to December 3 rd The paint system is in full accordance with the requirements in NORSOK M-501, rev. 5, system no Reference documents The National Institute of Technology, Materials Technology has tested the following product: Client: Jotun Coatings Product type: Paint system according to NORSOK system no. 1 Paint system: Jotun-11/N Substrate Steelpanels, blast-cleaned to Sa 2½ Resist 86 1 x 75 µm Part A Batch no: F Part B Batch no: 2361 Jotacote Universal Al 1 x 150 µm Part A Batch no: Lab Part B Batch no: EE A Hardtop PS5 1 x 60 µm Part A Batch no: F Part B Batch no: F Comments to the measured DFT: The roughness of the panels is µm. The laboratory interprets that the requirement in the NORSOK standard for the dry film thickness to be within ± 25 % of the NDFT is referring to the total system. The total system: The measured DFT of the total system was OK for all the exposed panels.

All test standards are either ISO- or ASTM-standards and the testing has been executed in full accordance with the requirements given in these standards and with the quality system of the laboratory. 3.1 Test regime, Ageing procedures acc. to ISO Salt Spray ISO h Low-temperature exposure at -20±2ºC 24 h UV-A ISO h One cycle, total time 168 h Total time, 25 cycles à 168 h 4200 h Acceptance Criteria 1. Corrosion creep from scribe: less than 3 mm (average of 9 point measured across the scribe) 2. Blistering ISO Rating 0 3. Rusting ISO Rating 0 4. Cracking ISO Rating 0 5. Adhesion ISO 4624 Min 5,0 MPa, max 50% reduction from original value 6. Overcoatable without mechanical treatment obtain minimum adhesion of 5 MPa. 3 parallel panels shall be tested. Two of three panels shall fulfil the requirements. Panels dried for minimum 14 days after exposure tests before adhesion tests were executed. For the exposure test 3 parallel panels were used. The pull off testing in acc. with ISO 4624 was executed with 6 parallels. Dollies 1,57 cm 2 were used. The uncertainty of the methods (the pull off test) is 10% for adhesion values less then 20 MPa and 15% for adhesion value more than 20 MPa. The scratches were made mechanically with a machine Sajo VRF 52 M. The ageing test was performed from July 11 th 2007 to December 3 rd Results All test results are given in appendix 1 and 2. Corrosion creep is calculated from the average of 9 measurements of the maximum width of the corrosion across the scribe. The maximum width is measured in the middle of the scribe, and in four points on each side of the middle, 5mm between each point. Corrosion creep (M = (C-W)/2, where C is the average of the 9 maximum widths of corrosion across the scribe, and W is the original width of scribe. Application details are given in appendix 3 and 4. Photograph of the tested panels are given in appendix 5. The results from fingerprinting will be given in a separate report.

4 Side Page 4 av of 4 5. Comments and conclusion The ageing resistance (cyclic salt spray/low-temperature exposure/uv resistance) was in accordance with the requirements. The overcoatability after the cyclic test was in accordance with the requirements. Adhesion test results on all exposed panels were in accordance with the requirements. Adhesion test results on unexposed panels were in accordance with the requirements. The paint system is in full accordance with the requirements in NORSOK M-501, rev. 5, system no 1.
