ANNEX VIIBASIC RULES FOR DEMONSTRATING COMPLIANCE WTH THE OML1. Heavy DutyMigration studies with heavy duty coatingsMethods applied- Samples were evaluated using directive 97/48/EC and 90/128/EEC, Annex 1,paragraph 2 and 5o The curing of the coatings involved has been made according to the numberof days and conditions as specified in the Technical Data sheet, 7 – 14 days,at 23°C, 50% relative humidity, alternative Hot-Cure, 5 days at 40 or 60°C.o Cured panels have been washed immediately after curing with steam during1 houro Ratio test area : volume simulant – 100 sq cm : 100 mlMethods applied:The investigation comprised the following determinations:Determination of the overall migration into 10% ethanol, after a contact period of10 days at 40°C.Determination of the overall migration into olive oil, after a contact period of 10days at 70°C.As an alternative to olive oil isooctane (2 days at 20°C) has been used in onecase.Determination of the specific migration of solvents (xylene, benzylalcohol,ethylbenzene, butanol/iso-butanol) into 10% ethanol.To determine the overall and specific migration into aqueous simulants from thesamples, the test specimens were immersed in the food simulant, 3% acetic acid and10% ethanol, and stored for 10 days at 40°C. After the contact period, the testspecimens were emptied and the procedure was repeated twice, using the samepanel and taking fresh simulant each time. After each storage period, the overallmigration was determined following similar methods as CEN method ENV 1186-3(version May 1994) (aqueous simulant) as closely as possible.50Europäische Vereinigung der Lack-, Druckfarben- und KünstlerfarbenindustrieEuropean Council of Paint, Printing Inks and Artists' Colours IndustryAvenue E.
