The EU Toy Safety Directive which came into force in 2013 has substaintially increased requirements on chemical substances.Restricted migration elements have been increased from 8 to 19 elements,which include trivalent chromium,hexavalent chromium and organotin.Restricted migration amount of N-nitrosamines and restriction of allergenic fragrances have been added.The limited amounts of lead,cadmium,hexavalent chromium,organotin have been decreased to 3.4,0.5,0.005,0.2 mg/kg respectively,and traditional toy testing methods such as inductively coupled plasma-optical emission spectrometry and gas chromatography-mass spectrometry cannot satisfy the testing requirements of hexavalent chromium,organotin,N nitrosamines and fragrances.This paper has briefly described the chemical requirements of TSD and corresponding testing methods,highlighted the technical progress and difficulties of testing methods of hexavalent chromium and organotin.
