It includes the following changes: - addition of Clause 3 - Terms and definitions; - addition of Clause 4 - Identification of conductors; - addition of subclauses 5.3.4 to 5.3.6 - Use of bi-colour combinations; - addition of subclause 6.2 - Identification of certain designated conductors; - addition of a new Annex A (informative) "Identification of certain designated conductors by means of colour code and alphanumeric"; - deletion of the old Annex A (informative) "Methods of marking PEN conductors in different countries". This bilingual version (2014-04) corresponds to the monolingual English version, published in 2007-05. It has the status of a basic safety publication in accordance with IEC Guide 104.
