ANNEX VIIIBASIC RULES FOR DEMONSTRATING COMPLIANCE WITH SMLs1. Heavy DutyHeavy duty coatings are evaluated using methods described in Directives 97/48/EC,85/572/EEC and 82/711/EEC.Simulants:Acetic acid:Acetic Acid is not suitable as food simulant for Heavy Duty Coatings due to severeeffect on the coating film (blistering and corrosion products) or in the case of lightmetal packaging due to corrosion of the metallic substrate. It is proposed to use 10%ethanol v/v as an alternative to 3% acetic acid.Olive Oil:For heavy duty coatings, the determination of specific migration of organic solvents inolive oil is rather difficult and in case for xylene the specific migration value givesvariable results. It is therefore recommended to use Isooctane (2 days at 20 deg C)as simulant. See conclusions in report migration studies from 12.02.1999ANNEX I to Directive 90/12/EEC of 23 February 1990 relating to plastic materialsand articles intended to come into contact with foodstuffsParagraph 2:Where the migration tests are carried out on samples taken from the material orarticle or on samples manufactured for the purpose, and the quantities of foodstuff orsimulant placed in contact with the sample differ from those employed in the actualconditions under which the material or article is used, the results obtained should becorrected by applying the following formula:1.2.3 // M = // m . a2 a1 . q // . 1 000Where:1.2 // M // is the migration in mg/kg; // m // is the mass in mg of substance releasedby the sample as determined by the migration test; // a1 // is the surface area in dm2of the sample in contact with the foodstuff or simulant during the migration test; // a2// is the surface area in dm2 of the material or article in real conditions of use; // q // isthe quantity in grams of foodstuff in contact with the material or article in realconditions of use.52Europäische Vereinigung der Lack-, Druckfarben- und KünstlerfarbenindustrieEuropean Council of Paint, Printing Inks and Artists' Colours IndustryAvenue E.
