1. May, 2007 TurboCare Sp. z o.o. NDT TESTS

2. Privileged & Confidential – Page 2 scope of tests On usual basis we perform : Material tests Strength tests Visual examination PT, HD, MT and UT tests RT tests – in cooperation We use highest quality materials from companies such as : MR Chemie Gmbh and TIEDE We use highest quality machines made by companies such as: TIEDE, Krautkramer, Equotip and DEUTSCH

3. Privileged & Confidential – Page 3 material tests Material tests; All material tests are done on basis of proper EN standards; In preparation of samples process we use abrasive papers and diamond pastes or aluminum oxide suspensions; We use only materials from known companies (e.g. STRUERS); Preparation of replicas consist in vacuum evaporating and grading of tested materials – we use aluminum, gold or coal; Microstructure observation showed in replicas is done by ZEISS NEOPHOT 32`microscope. Photographic recording is done by CCD-Insight Spot digital camera interfaced with photo processing computer system; If necessary, for microstructure (samples or replicas) observation we use – in cooperation with Wroclaw Technical University – scanning or emission electron microscopes.

4. Privileged & Confidential – Page 4 non destructive material tests Negative of triafol replicas are made on live object, removed and fixed by adhesive tape on sample glass; Sample replicas are prepare by gold, aluminum or coal for further tests;

5. Privileged & Confidential – Page 5 destructive material tests Example samples after impact resistance tests; Special system for strength tests in 700°C;

6. Privileged & Confidential – Page 6 endoscopy and visual examinations Whole scope of endoscope and visual examinations are done with careful photographic and descriptive documentation; Welch Allyn Videoprobe 2000 videoscope test – Ø 9mm 3m probe; Olympus endoscope – Ø 9mm 1,5m probe; Pipelines endoscopy with industrial television from pipes with Ø 40mm diameter to 15m length;

7. Privileged & Confidential – Page 7 ultrasonic tests Tests are done according to EN standards and SIEMENS specific instructions of elements (parts) and specific materials tests; For tests we use Krautkramer and Starmans equipment;

8. Privileged & Confidential – Page 8 ultrasonic tests Bearings tests; Bolts tests; Casings tests; Journal and shaft tests; Rivets and blades tests; Welds tests;

9. Privileged & Confidential – Page 9 wall thickness measurements We perform thickness measurements using modern ultrasonic equipment; Wall thickness: Casings; Pipelines; Heat exchangers surfaces; Hard to reach elements and elements available only from one side;

10. Privileged & Confidential – Page 10 magnetic powder tests Tests are performed according to EN standards and SIEMENS specific instructions of elements (parts) and specific materials tests; For tests we use TIEDE and DEUTSCH equipment;

11. Privileged & Confidential – Page 11 magnetic powder tests All found defects are carefully documented and finally shown in protocol, with exact localization and photography;

12. Privileged & Confidential – Page 12 magnetic powder tests During testing of high importance elements we use high sensitivity agents and we perform observation in UV light;

13. Privileged & Confidential – Page 13 long blades tests Magnetic powder test in white and UV light; Blade root dye penetrant test; Blade root and rivets ultrasonic test; Blade hardness test;

14. Privileged & Confidential – Page 14 dye penetrant tests All elements made from non ferromagnetic materials are tested with dye penetrant method – observation is performed as well in white light as in UV light;

15. Privileged & Confidential – Page 15 hardness tests We perform all kinds of hardness tests of materials and machine elements; Vicers method hardness test with ultrasonic hardness tester (in Vickers, Brinell or Rockwell scale); Energy method hardness test with EQUOTIP-2 hardness tester (in Vickers, Brinell or Rockwell scale);

16. Privileged & Confidential – Page 16 defect analysis Using our knowledge acquired during many years of experience we could indicate probable causes of defects, formed during production as well as during operation;

17. Privileged & Confidential – Page 17 certificates Tests leading personnel has all required certificates; Training scope meets requirements of EN473 standard
