The nickel drop test is mainly aimed at earrings, necklaces, bracelets, anklets, rings, watchcases, bracelets and handles.
Buttons, fastening devices, rivets, zippers and metal signs on clothes. Nickel-nickel release test nickel is an easy cause.
Limit requirements for exposure to nickel oxide: European standards stipulate that the release of nickel in clothing, jewelry and other products shall not exceed.
0.2 μ g/cm2/week.
Test process: Put the test object released by nickel into artificial sweat test solution for 7 days. Using atomic absorption spectroscopy, electricity
Inductively coupled plasma spectroscopy or other suitable analytical methods are used to measure the concentration of dissolved nickel in the solution. The amount of nickel released was measured by microscopy.
G/cm2/week (ug/cm2/ week).
General test method:1997 On July 20th, the European Union issued two new harmonized standards according to the requirements of 94/27/EC, namely
1811and EN 12472 have determined the quantitative analysis method of standard nickel release.
The sensitive meta-detection method is as follows: nickel release from products in direct long-term contact with skin (en1811:1999
Products suitable for electroless plating); And a test for measuring nickel release from electroplated coated articles after abrasion.
(EN 12472: 1999, suitable for electroplating products)
Sue. For metal testing only, the release of nickel should not exceed 0.5μg/cm2/ week.
