Certain Cetie documents are developed with the intention that these be subsequently proposed through the appropriate channels as a basis for developing a standard in CEN and/or ISO. In this case, they can be considered pre-standards. It is underlined that reference documents developed by Cetie do not have the status of standards, a term which is reserved for standards published by official national and international standards organisations such as Afnor, DIN, BSI, UNI, AENOR, ISO, etc., after a public enquiry. When a standard thus developed from a proposal from Cetie is published, Cetie systematically withdraws the corresponding Cetie data sheet from available downloadable publications and redirects all requests to the standard. The document remains accessible on request as a bibliographic reference, which may be cited in particular in the developed standard, and also to the members of the working group which prepared it. In all cases it is made clear that only the publishes standard must henceforth be used as a reference.
