Assessment framework and manuals

Ctgb makes assessments based on a set of criteria: the assessment framework. This framework is established in European legislation (regulations and directives). This legislation applies to all EU Member States, but country-specific regulations and requirements can also apply.

European harmonisation

The European Union considers the correct use of biocidal products to be very important. To manage this properly, the EU has adopted binding legislation that applies to all Member States: the "European Regulation for the placing on the market and use of biocidal product", otherwise known as the Biocidal Products Regulation (EU) 528/2012. The aim of this legislation is to promote European harmonisation. Individual differences in assessments between Member States will be reduced, so an application in one country can also be recognised in another country, by means of mutual recognition.


To support the implementation of legislation guidance documents are developed under the auspices of the European Chemicals Agency (ECHA). The guidance documents describ the best way to deal with these obligations within specific frameworks. These guidance documents can be legal, procedural or scientific in nature. During the development of such documents, Ctgb sometimes takes the role of developer or commentator.


To increase transparency on active substance approval and authorization of biocidal products in the Netherlands, Ctgb developed two manuals (only in Englsih) that cover successively the technical and procedural framework for biocide authorisation:

  • Registration Manual: this manual informs you about the application processes (including application and assessment process).
  • Evaluation Manual: technical instructions and information on assessment standards, assessment framework, and calculation models that are used to conduct the assessments.

The manuals of Ctgb refer to the underlying guidance documents.
