----------------------------------------------------------------------------------------------------------------
Note: Gases concentration are expressed in parts per million per volume (ppmV).
Notes to Table A.1.1:
(a) The acute toxicity estimate (ATE) for the classification of a substance is derived using the LD50/LC50 where
  available ;
(b) The acute toxicity estimate (ATE) for the classification of a substance or ingredient in a mixture is
  derived using:
 (i) the LD50/LC50 where available. Otherwise,
 (ii) the appropriate conversion value from Table 1.2 that relates to the results of a range test, or
 (iii) the appropriate conversion value from Table 1.2 that relates to a classification category;
(c) Inhalation cut-off values in the table are based on 4 hour testing exposures. Conversion of existing
  inhalation toxicity data which has been generated according to 1 hour exposure is achieved by dividing by a
  factor of 2 for gases and vapors and 4 for dusts and mists;
(d) For some chemicals the test atmosphere may consist of a vapor which is near the gaseous phase. In these
  cases, classification is based on ppmV as follows: Category 1 (100 ppmV), Category 2 (500 ppmV), Category 3
  (2500 ppmV), Category 4 (20000 ppmV).
The terms ``dust,'' ``mist,'' and ``vapor'' are defined as follows:
(i) Dust: solid particles of a substance or mixture suspended in a gas (usually air);
(ii) Mist: liquid droplets of a substance or mixture suspended in a gas (usually air);
(iii) Vapor: the gaseous form of a substance or mixture released from its liquid or solid state.

    6. In Appendix A on page 50447, correct Table A.1.2: Conversion 
from experimentally obtained acute toxicity range values (or acute 
toxicity hazard categories) to acute toxicity point estimates for use 
in the formulas for the classification of mixtures, to read as follows:
