5. Types of changes and evaluation timeframes

Changes to a biocidal product or biocidal product family authorisation fall into 3 categories:

  • administrative – changes that do not result in changes to the risk assessment, efficacy or the physical or chemical properties of the product
  • minor – changes that result in limited changes to the risk assessment, efficacy or the physical or chemical properties of the product
  • major – changes that cannot be categorised as administrative or minor changes

These are examples of the different categories of change and the approximate timeframes for evaluation:
