Kadar se izvajajo raziskave aktivne snovi, proizvedene v laboratoriju ali v poskusni proizvodnji, jih je treba ponoviti s tehnično aktivno snovjo, razen če je mogoče utemeljiti, da je uporabljena testirana snov s stališča ekotoksikološkega preskusa in ocene, enaka.
Where studies are conducted using active substance produced in the laboratory or in a pilot plant production system, the studies must be repeated using active substance as manufactured, unless it can be justified that the test material used is essentially the same, for the purposes of ecotoxicological testing and assessment.
