10 x DIN A4 per simulant (please label the food-contact side) or 20 containers, packed in aluminium foil
OM1: 10 days at 20°C Any food contact at frozen and refrigerated conditions.
OM2: 10 days at 40°C Any long term storage at room temperature or below, including when packaged under hot-fill conditions, and/or heating up to a temperature T where 70 °C ≤ T ≤ 100 °C for a maximum of t = 120/2^((T-70)/10) minutes. Test OM 2 covers also food contact conditions described for OM1 and OM3.
OM3: 2 h at 70°C Any food contact conditions that include hot-fill and/or heating up to a temperature T where 70 °C ≤ T ≤ 100 °C for maximum of t = 120/2^((T-70)/10) minutes, which are not followed by long term room temperature or refrigerated storage.
OM4: 1 h at 100°C High temperature applications for all food simulants at temperature up to 100 °C.
OM5: 2 h at 100 °C (or 1 h at 121°C) High temperature applications up to 121 °C. Test OM 5 covers also food contact conditions described for OM1, OM2, OM3, OM4. It represents the worst case conditions for all food simulants in contact with polyolefins. When testing materials with a polyolefin food contact layer, OM5 allows to clear the material for any use condition even exceeding 121°C (within the limits of technical suitability and SML compliance).
OM6: 4 h at 100°C Any food contact conditions at a temperature exceeding 40 °C, and with foods for which point 4 of Annex III assigns simulants A, B, C or D1. It represents worst case conditions for food simulants A, B, C and D1 in contact with non-polyolefins.
OM7: 2 h at 175°C High temperature applications with fatty foods exceeding the conditions of OM5.Test OM 7 covers also food contact conditions described for OM1, OM2, OM3, OM4, OM5. It represents the worst case conditions for fatty food simulants in contact with non-polyolefins. In case it is technically not feasible to perform OM7 with food simulant D2 the test can be replaced by either test OM8 or test OM9 as appropriate given the intended or foreseeable use. Both tests involve testing at two test conditions for which a new test sample shall be used for each test.
