Corrosive substances

The classification rules for corrosive substances will change and will be based on the generic and specific concentration limits for each of the substances in the mixture.

The assignment of the corrosive mixtures to the packing groups presented in 2.2.8.1.3 is carried out in accordance with 2.2.8.1.6 on the basis of the whole thickness skin destruction test by measuring the duration of application and the observation period with two alternative methods:

  • 2.2.8.1.6.2 the principle of extrapolation where data for similar mixtures are available to assess skin corrosion,
  • 2.2.8.1.6.3 the calculation method where data for all components are available on skin corrosion.
