A.1.2 Scope and conditions of the restriction
Based on the justifications summarised in section A.2 and discussed in the report, the followingrestriction is suggested for chromium (VI) (hexaval
ent chromium) in leather:
•Articles of leather, coming into direct and prolonged or repetitive contact with the skin,shall not be placed on the market if the leather contains chromium (VI) in concentrationsequal to or higher than 3 mg/kg. Hexavalent chromium is not intentionally used in the preparation of leather from skins and hides and in the manufacturing of articles of leather, but may be formed during the processing. Under controlled conditions chromium tanned leather and articles of chromium tanned leather have be found without hexavalent chromium. Some studies have shown that already sensitised individuals may react at a concentration of 3 ppm
of hexavalent chromium, but for practical reason to determine compliance with the restriction the limit has been chosen. The limit represent the quantitative limit of detection of the analytical method used to determine the content of hexavalent
chromium is in leather in its current state. The method is the international standard EN ISO 17075:2007.
