3.9.2 Biological Conditions
The severity of these requirements is in conformity with: IEC 721-3-4 class
/4B1/ and ETS 300 019-1-4 Class 4.1.
3.9.3 Chemically Active Substances
The severity of these requirements is in conformity with: IEC 721-3-4 classes
/4C2(4C1)/ and ETS 300 019-1-4 Class 4.1.
Note: The values are average yearly levels of airborne contaminants that can
be accepted. It is assumed that one of the contaminants is dominant at
each site, and that the other is present in insignificant amounts.
3.9.4 Mechanically Active Substances
The severity of these requirements is in conformity with: IEC 721-3-4 class
/4S2/ and ETS 300 019-1-4 Class 4.1.
3.9.5 Mechanical Conditions
The severity of these requirements is in conformity with: IEC 721-3-4 class
