| Notes |
B (Some substances (acids, bases, etc.) are placed on the market in aqueous solutions at various concentrations and, therefore, these solutions require different classification and labelling since the hazards vary at different concentrations.Entries with Note B have a general designation of the following type: ‘nitric acid … %’.In this case the supplier should state the percentage concentration of the solution on the label. Unless otherwise stated, it is assumed that the percentage concentration is calculated on a weight/weight basis.) D (Certain substances which are susceptible to spontaneous polymerisation or decomposition are generally placed on the market in a stabilised form. It is in this form that they are listed in this spreadsheet.However, such substances are sometimes placed on the market in a non-stabilised form. In this case, the supplier should state on the label the name of the substance followed by the words ‘non-stabilised’.) |
