This article introduces the advancement of four novel diagnostic testing methodologies for evaluating the mechanical and chemical properties of cable insulation: Indenter Modulus (IM), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric analysis (TGA) and X-Ray Fluorescence Spectral Analysis (XRF). Experiments were performed on diverse samples of widely used nuclear-qualified cable polymer materials, including Ethylene Propylene Rubber (EPR) and Crosslinked Polyethylene (XLPE), all with a Chlorosulphonated Polyethylene (CSPE) jacket. Samples from various vintages were subjected to additional temperature ageing in many stages, to establish field testing acceptability requirements and assess the remaining lifespan of the polymer insulation. Diagnostic tests were performed and some preliminary results are reported"},{"@xml:lang":"sl","#text":"Prispevek predstavlja ugotovitve o izvajanju različnih mehanskih in kemijskih diagnostičnih postopkov za izboljšanje spremljanja stanja izolacije kablov v Nuklearni elektrarni Krško (NEK). Članek predstavlja uvajanje in razvoj štirih novih metod diagnostičnega testiranja za ocenjevanje mehanskih in kemijskih lastnosti izolacije kablov: indenter modul (IM), diferenčna dinamična kalorimetrija (DSC), Fourierjeva transformacijska infrardeča spektroskopija (FTIR), termogravimetrična analiza (TGA) in rentgenska fluorescenčna spektralna analiza (XRF).Eksperimenti so bili izvedeni na različnih vzorcih široko uporabljanih jedrsko kvalificiranih polimernih materialov kablov, vključno z etilen-propilen gumo (EPR) in zamreženim polietilenom (XLPE), vsi s plaščem iz klorosulfoniranega polietilena (CSPE). Vzorci iz različnih obdobij so bili dodatno termično starani v več stopnjah, da bi določili zahteve za kriterije sprejemljivosti terenskih testiranj in ocenili preostalo življenjsko dobo polimerne izolacije.
