According to the Biocidal Products Regulation (EU 528/2012), the in-situ generation of active chlorine from sodium chloride by electrolysis has to be authorised either by the user of the in-situ generated active substance or by other interested parties like the supplier of the sodium chloride or the producer of the device used for the in-situ generation. Moreover, the use of devices without corresponding authorisation is prohibited, although transitional provisions might still apply.

The main purpose of ISA Consortium is to achieve suitable authorisations of a biocidal product and a biocidal product family for applications in water treatment in particular with respect to the product types 2, 4 and 5 according to the BPR. This milestone was achieved prior to the deadline of 1 July 2022.
Therefore, all members of ISA Consortium can ensure vis-à-vis customers that corresponding devices are considered in the application for product authorisation and the user is not obliged to apply for product authorisation.

ISA Consortium also contributes to the development of the outstanding technical guidance by the responsible authorities on European level for the product authorisation of in-situ cases under the BPR and to the development of technical standards relating to the in-situ generation of active chlorine as the in-situ generated active substance.
