Description

The purpose of this document is to specify requirements for marking, identification, leaktightness, electrical and operational safety and mechanical resistance for sanitary tapware with opening and closing controlled electronically. The conditions of use for the supply system type are specified in Table 2: [Table 2] Annex B lists possible consequences of using a product outside its recommended operating range.
