Ηλεκτρικά και ινοοπτικά καλώδια - Μέθοδοι δοκιμής μη μεταλλικών υλικών - Μέρος 301: Ηλεκτρικές δοκιμές - Μέτρηση της διηλεκτρικής σταθεράς στους 23 °C μειγμάτων πλήρωσης

IEC 60811-301:2012 gives the procedure to determine the permittivity at 23 °C which typically applies to filling compounds used for optical cables, communication cables and optical fibre cables. IEC 60811-301:2012 cancels and replaces Clause 9 of IEC 60811-5-1:1990, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100:2012. This publication is to be read in conjunction with <a href='http://webstore.iec.ch/webstore/webstore.nsf/ArtNum_PK/46164'>IEC 60811-100:2012</a>.
