Aspiration
Additivity approach
The generic cut-off value for Aspiration is 1 % (CLP, Annex I, Table 1.1). This means that if mixture consists of substances with Aspiration hazard each present at a concentration below 1 % and even if the sum of their concentrations is above 1 % the mixture will not be classified for Aspiration.
A mixture is classified as Category 1 (Asp. Tox. 1) when:
| ● |
the sum of the concentrations of Category 1 (Asp. Tox. 1) ingredients is ≥ 10 % , and |
| ● |
the mixture has a kinematic viscosity ≤ 20.5 mm2/s, measured at 40 ºC (CLP, Annex I, 3.10.3.3.1.2). |
In the case of a mixture which separates into two or more distinct layers, the entire mixture is classified as Category 1 (Asp. Tox. 1) if:
| ● |
in any distinct layer the sum of the concentrations of Category 1 (Asp. Tox. 1) ingredients is ≥ 10 % , and |
| ● |
it has a kinematic viscosity ≤ 20.5 mm2/s, measured at 40 ºC (CLP, Annex I, 3.10.3.3.1.3). |
Generic concentration limit is 10 %.
The below formula provides the conversion between dynamic and kinematic viscosity (CLP, Annex I, 3.10.1.6.2).
Dynamic viscosity (mPa s)
Density (g/cm3)
=
Kinematic viscosity (mm2/s)

The mixture has a kinematic viscosity ≤ 20.5 mm2/s, measured at 40ºC.
Cut-off limits
| − |
Concentrations of substances A, B and C are above the generic cut-off limit 1 % (CLP, Annex I, Table 1.1), therefore, their concentrations are taken into account. |
| − |
Concentration of substance D is below the generic cut-off limit 1 % (CLP, Annex I, Table 1.1), therefore, its concentration is not taken into account. |
Specific and Generic concentration limits
| − |
Because no specific concentration limits are applied for A, B and C their concentrations must be compared to generic concentration limit. |
Calculation of 'Asp. Tox. 1'
| − |
Concentrations of substances A, B and C must be summed.
conc. A + conc. B + conc. C = 1.1 + 5.0 + 4.0 = 10.1 %
The obtained value is above the generic concentration limit 10 %. This leads to classification Asp. Tox. 1 . |
Selection of hazard category
| − |
The mixture is classified as 'Asp. Tox. 1'. |
Selection of hazard statements
| − |
H304 corresponds to 'Asp. Tox. 1'. |
Selection of pictogram and signal word
| − |
Pictogram GHS08 and signal word 'Danger' correspond to 'Asp. Tox. 1'. |
Selection of precautionary statements
| − |
For H304 following precautionary statements are applied: P301+P310, P331, P405, P501. |

The mixture has no a kinematic viscosity ≤ 20.5 mm2/s, measured at 40ºC.
Calculation of 'Asp. Tox. 1'
| − |
Despite the sum of substances A, B, C and D is above a generic concentration limit 10 %, the mixture is not classified 'Asp. Tox. 1' because the criterium of kinematic viscosity is not fulfilled. |
Classification of the mixture
The mixture is not classified.
