Question
The KNX standard is internationally standardised under the reference ISO/IEC 14543-3.
Answer
True
KNX is standardised by ISO/IEC 14543-3 (Information technology — Home Electronic System (HES) Architecture). It is also covered at European level by the EN 50090 series and at Chinese level by GB/Z 20965. This multi-level recognition is one reason KNX is positioned as a vendor-neutral open standard.
