Survey and health assessment of chemical substances in jewelleries
Appendix H: Samples where double tests varied
In the table below the results from the migrations analyses of the 25 jewellery parts are presented. Values with < ahead indicate samples where migration did not take place in a concentration which exceeded the detection limit. In cases where two values are presented (e.g. 93/540), the two values represent results belonging to the two double tests. The reason why both are presented is that the value varied with more than 50%. Other values represent an average of the two double tests.
