Foreword
This standard is identical with EN1186-2.2002 "Test methods for plastic food contact materials and articles the overall migration in olive oil
Total immersion "(in English).
In order to meet China's national conditions and ease of use, this standard does the following editorial changes, the main differences are as follows.
a) Remove the BSEN1186-2.2002 in the previous page, directory, foreword, introduction, appendix ZA, references and after page;
b) In the "standard" instead of EN1186-2. in 2002, "This part of this standard";
c) Adjustment of Chapter 4 Reagents number and order to adapt to China's national standards for the preparation requirements;
d) instead of as a decimal by decimal comma ",". ",";
e) "ml" changed to "mL" representation;
f) Chapter 3 of the Articles respectively BSEN1186-2.2002 paragraphs of Chapter 3;
g) 6.1,6.2,6.3,6.4,7.1,7.3,7.5 and 8.1 respectively in Articles BSEN1186-2.2002 Section 6.1,6 .2,
The 6.3,6.4,7.1,7.3,7.5 8.1 and paragraphs;
The h) 7.6.1 Articles correspond BSEN1186-2.2002 paragraphs of Section 7.6.1;
i) in 7.6.2.2 and 7.6.2.3 respectively Articles BSEN1186-2. paragraphs 7.6.2.2 and 7.6.2.3 of the 2002 first article;
j) in accordance with the referenced EN1186-1. provision of content-2002 No references to the provisions to be adjusted accordingly;
k) in accordance with the provisions of the note number of national standards for the preparation of the requirements to be adjusted.
The Standard Appendix A, Appendix B, Appendix C, Appendix D is a normative appendix, Appendix E, Appendix F for the informative appendix.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.

Food contact materials - Polymer
Test methods for overall migration into olive oil by total immersion method
1 Scope
This standard specifies the food contact material at the selected time in more than 20 ℃ and less than 100 ℃ temperature conditions of the polymer material ---
Material or article in fatty food simulants olive oil in the overall migration by total immersion measurement method.
This standard is most suitable for use in food contact materials --- polymer material films or sheets, but also for the majority of the appropriate size can be cut again
Member of the container or article.
NOTE. The standard for the use of olive oil and fat mimetic that is prepared, after appropriate changes may be other fatty food simulants Food simulant D for call
Material such as synthetic mixture of triglycerides, sunflower oil and corn oil. These other fatty food simulants will produce the olive oil methyl ester is not
Mimetics with methyl esters chromatogram. Select the appropriate other fatty food simulants methyl ester peaks for the sample extracted from the mimetic
It was measured.
This standard is applicable to most types of food contact materials --- polymer materials.

Principle 3
3.1 Determination of food contact materials intended for food contact --- mass loss per unit area of a sample of polymer materials, food contact material obtained
The total amount of material --- Migration polymer material samples.
3.2 According to the conditions of use determines whether the selected test conditions, see EN1186-1.2002 in Chapters 5 and 6.
In the more than 3.3 and less than 20 ℃ 100 ℃ temperature range, the known weight of the sample is exposed to a time immersed in olive oil, the olive from
Olive oil removed, olive oil to remove adhering surface, re-weighed.
3.4 specimens usually leave olive oil adsorption. Olive oil extraction adsorbed, and converted to methyl esters by gas chromatography after quantitated using
set. By boron trifluoride/methanol mixture with a fatty acid (produced by the hydrolysis of potassium hydroxide oil) methylation reaction process. It is sucked and extracted
Prior to attachment of olive oil, add internal standard heptadecanoic acid triglyceride, to ensure that any active substance or extractable food contact materials --- scores
Sub-component material can also be obtained with the extraction of olive oil as the internal standard response. The same will happen in the standard hydrolysis and methylation reactions, which can be corrected
Positive hydrolysis and methylation process invalid response.
3.5 Sample subtracted from the initial mass of the sample in the quality of olive oil through the net after soaking, to obtain overall migration after (sample was soaked in olive oil
Net mass. mass of the sample was removed from the olive oil by subtracting the mass of olive oil adsorbed on the sample).
The total mass loss of 3.6 milligrams per square decimeter sample surface area (mg/dm2) said the overall migration of at least three separate measurement sample knot
Reports the average fruit.
3.7 Taking into account the testing process will produce an error and this error is difficult to detect, such as sample loss or contamination of the oil phase, it is estimated to
