答案（中文）
如果混合物的吸入毒性基于其成分，则需要满足两个条件。首先，混合物中一种或多种被归类为吸入毒性第1类的物质的含量必须总计达到或超过10%。其次，混合物的运动粘度必须在40°C下测量时等于或低于20.5 mm²/s（CLP附件I第3.10.3.3.1.1点）。当同时满足这两个条件时，混合物必须被归类为吸入毒性第1类。
Answer (EN)
Where the aspiration toxicity of a mixture is based on its components, two conditions need to be met.
Firstly, a mixture must contain a total of 10 % or more of a substance or substances classified in Aspiration Toxicity Category 1.
Secondly, the kinematic viscosity of the mixture must be at or below 20.5 mm2/s, measured at 40°C (point 3.10.3.3.1.1 of Annex I to CLP).
When these conditions are both met, the mixture must be classified in Aspiration Toxicity Category 1.
