2 TZ/MSO/BBJ The Danish Technological Institute, Centre for Materials Testing has tested a sample type according to our food safety test procedure. Sample received Product name Production/serial no. Size/diameter Danish Technological Institute, DTI sample no. Frying pan Serial number Diameter Sample number PICTURE OF TEST SAMPLE Photo 1. Frying pan, serial no.: serial number, size in diameter. The foot safety test also covers the following product(s): Product name Size/diameter Frying pan Purpose of the food safety test The purpose of the test programme is to validate the food-safety of the cookware according to given international standards and guidelines. The food-safety test insures that the cookware is: manufactured in accordance with good manufacturing practise not transfer its constituents to foodstuff in quantities which could endanger human life and change the quality, taste or colour of the food-stuff offering highest hygiene of foodstuffs Page 1 of 7

3 TZ/MSO/BBJ Food safety test procedure The procedure of the food safety test contains the following analysis and investigations: 1. Analysis of the metal body of the cookware 1.1 Optical Emission Spectroscopy (OES) analysis according to ASTM E 415 and ASTM E 305 to determine the chemical composition of the metal body of the cookware. 1.2 Comparison of the chemical composition with the international accepted standard DS/EN 601 "Aluminium and aluminium alloys - castings - chemical composition of castings for use in contact with food", recommended in the Technical Document Guidelines on Metals and Alloys used as Food Contact Materials of the European Council, 9 th March Metallographic investigation and validation of the homogeneity made on a cross section of the body metal of the cookware according to ASTM E 3-80 (1995) using a large incident-light camera microscope at 200x magnification. 2. Investigation and analysis of the indirect food additives: Internal surface coating components 2.1 Materialographic investigation, comparison and validation of the interior of the cookware according to the statements of the manufacturer and good manufacturing practice. A materialographic cross section from the pan bottom of the cookware is made according to ASTM E 3-80 in order to make the surface coating structure visible. The cross section is examined in a large incident-light camera microscope at magnifications ranging from 400x to 800x. Analytical Equipment: Microscope: Neophot 32 Analysis Software: AnalySiS Areas and spots in the interface, ceramic- and coating layers on the sample are analysed in a scanning electron microscopy (SEM), equipped with facilities for micro x-ray analysis of inorganic constituents (EDX). The validation of constitutes determined is carried out according to the statements in the Guidelines on Metals and Alloys used as Food Contact Materials of the Council of Europe.

4 TZ/MSO/BBJ SEM-Type: Leo440 EDX-System: Oxford, Link Isis 300, revision 3.35 Analyser: Oxford, Sili-detector, res. 133eV 3. Validation of the indirect food additives: Internal organic coating components 3.1 Test of migration according to BfR LI, BgesundhBl. 37, 366 (1994) "Heat resistant polymer coatings for grill-, cook- and bakeware" - Systems for manufacture of coatings for frying and cooking utensils. Alternatively the test is carried out according to FDA CFR Validation of the coating components according to the BfR LI and the Code of Regulations, Title 21, Part 175/C and 177, U.S. Food and Drug Administration (FDA). 4. Documentation 4.1 A written report with DTI logo containing the test results, photos and conclusion in English 4.2 A certificate with DTI logo which states that the cookware is food safety tested and approved Page 3 of 7

5 TZ/MSO/BBJ Results 1. Analysis of the metal body of the cookware 1.1. The chemical composition of the cast metal body is analysed (see appendix 2) and found to be % aluminium (Al) % silicon (Si) % iron (Fe) % manganese (Mn) % magnesium (Mg) % titanium (Ti) % copper (Cu) % zinc (Zn) % lead (Pb) The remaining alloying elements are below 0,05% 1.2. Compared with the international standard DS/EN 601, none of the analysed alloying elements are found to exceed the maximum values stated in the above mentioned standard The metallographic cross section of the metal body shows a aluminium cast structure with different size dendrites and few small pores. 2. Investigation and analysis of the indirect food additives: Internal surface coating components 2.1. The Analysis of the surface components and metal body of the cookware shows that the cast casserole, serial no.: serial number has four layers on top of the metal body (see appendix 1): Non-stick topcoat with thin plate-or needle-like particles Mid coat Base coat with large particles Ceramic (plasma sprayed) Page 4 of 7

6 TZ/MSO/BBJ 2.2. The SEM and EDX analysis of the internal surface components from the center of the cast frying pan, serial no.: serial number (se appendix 3 to 8) shows that only components that can be expected from this type of cookware are detected The investigation shows that no components are found that can endanger human life or change the quality, taste or colour of the foodstuff. Only components, phases and alloying elements that can be expected from this type of cookware are determined. 3. The validation of the indirect food additives: Internal organic coating components The organic coating material applied by the customer is : 1. Base coat 2. Midcoat 3. Topcoat Manufactured by Company name According to our food safety test procedure the company has the possibility to deliver actual test certificates of another accredited third party. The report confirms that the coating system system name is in compliance with the FDA CFR /BfR LI. Based on this we are able to confirm that the coating system system name meets the requirements in the food safety test procedure section 3. Page 5 of 7

7 TZ/MSO/BBJ Conclusion The Danish Technological Institute, Centre for Materials Testing has approved sample type, serial no.: serial number, size according to the food safety procedure stated above.
