Three hundred and ninety-five new frames were tested for evidence of nickel release using dimethylglyoxime and ammonia. For areas of CE-marked frames in direct contact with the skin a considerable improvement was found over the previous such survey by the authors, carried out before the widespread introduction of CE marking. However, free nickel was found in 6.5% of CE-marked metal frames (excluding titanium and titanium alloy) in such areas and a majority of half joints. Some titanium alloy frames also tested positive for nickel in areas in contact with the skin.
使用丁二酮肟和氨水对395个新镜架进行了镍释放检测。对于直接接触皮肤的带有CE标志的镜架区域，与作者此前在CE标志广泛采用之前进行的此类调查相比，有了显著改善。然而，在此类区域以及大多数半关节处，6.5%带有CE标志的金属镜架（不包括钛及钛合金镜架）中发现了游离镍。一些钛合金镜架在与皮肤接触的区域镍检测也呈阳性。
