Note 4 of 2.2.3.1.1 in ADR refers to "highly toxic", "toxic", or "slightly toxic". However, there is no explanation of these in the chapter 1.2 definitions. Where can I find the criteria for these allocations?
Additionally, if there can be three different types of “toxics”, why does Class 3 not set down criteria for “highly flammable”, “flammable”, or “slightly flammable”?
