Before using a particular substance in production, it is important to check the manufacturer's list.Without restriction if a product contains only substances to be tested, only the characteristics of global migration should be. In such cases, the food moves a laboratory test to detect the amount of product. This is purely a health measure intended to show that the substance will migrate, but limits the total amount you are traveling.
In fact, all food contact materials should be disabled are possible, 60 mg / kg or mg/dm2 10 no more than a general migration to the popular perception that these two figures that show the results for the 6 dm2 ratio of 1 kg food.The wrap up packing a large number of substances lists, there are specific migration limits. These limits are determined by individual characteristics of these substances. Some items have a bad taste in food is dealt, in large measure on the packaging, while other hazardous substances to the human body, the packaging of the large food to go. Therefore, there are many reasons why there may be restrictions on certain substances.
If a product which food, specific migration limits come into contact with the subject, the migration and migrating substances are to be tested this product. However, the calculation does not require proof that a product should be tested at the border and testinWhen observed.Application to justify, in view of the product to use. A plastic mixture, for example, a plastic jar of jam, as will be tested under conditions of equality, because the exposure time and temperature of the test is taken, the system, stay for shorter periods of exposure to dress requirements in the high temperature, while a pot, for example, must drink at lower temperatures can be stored for a longer period.
In mediating the appropriate test conditions, we rely on Council Directive 82/711/EC and following amendments. Instructions specify that the table contains different lengths of contact time trial. If you dress warm for 45 minutes is expected to be in contact with food, one hour test period. For jar in contact with food have come to expect during a long time, and therefore the item will be tested over a period of 10 days.
Director also provides tables to ensure the contact temperature, maximum temperature has tested the product can be suspended. Consequently, an article expected to use the test as realistic as possible is judged in the construction of programs - and the "worst case" will be elected. If a product can be used, for example, both in the refrigerator at room temperature, the test is always kept at higher temperatures. Therefore, the results also apply to the case of low temperatures.
