2.1 Classification of the substance or mixture

1272/2008 The only substances important for hazard classification of Ni-alloys in the solid form are Ni and potentially Co. In accordance with (EC) Regulations 1272/2008 (CLP) and 790/2009 (CLP-ATP1), nickel is classified as a carcinogen category 2, Specific Target Organ Toxicity Repeated Exposure 1 and skin sensitizer 1. The CPL Regulation has introduced changes in the classification of nickel when compared with the Dangerous Substance and Dangerous Preparations Directives, which it superseded for mixtures starting 2015 june 1st. As a result, Ni-alloys, all containing above 10%Ni, if considered as mixtures are classified as carcinogen category 2. According to EC Regulation 1272/2008, alloys containing nickel are classified for skin sensitisation when the release rate of 0,5μg Ni/cm2/week, as measured by the European Standard reference test method EN 1811, is exceeded. Description According to EC Regulation 1272/2008, alloys containing Cobalt are classified for skin of hazards sensitisation and as respiratory sensitiser when the Co content is above 1,0% and for labelling when the Co content is above 0.1% to protect already sensitised individuals. Dust and fume may be generated during processing e.g. in welding, cutting and grinding. If airborne concentrations of dust and fume are excessive, inhalation over long periods may affect workers´ health, primarily of the lungs. Dust and fume quantity as well as composition depend on specific practice, on parent and welding material. Different alloying elements (including Cr for Cr-containing Ni-alloys) may be found under various oxidized forms in welding fumes. Welding or allied processes should only be performed by trained workers. Guidance such as American National Standard Z49.1 and German BGR-220 give valuable information on Safety in Welding and Cutting. 2. Composition - Information on substances in the Ni-alloys articles
