IEC 60811-508:2012 gives the procedure for a pressure test at high temperature, which typically applies to thermoplastic compounds used for insulating and sheathing materials. IEC 60811-508:2012 cancels and replaces Clause 8 of IEC 60811-3-1:1985, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. Significant technical changes with respect to the previous edition are as follows: - re-statement of oven characteristics, especially relating to anti-vibration and to temperature control; - enhanced detail as to the preparations and testing of flat cables; - enhanced detail as to thickness and dimensional measurements. See also the Foreword to IEC 60811-100:2012. This publication is to be read in conjunction with IEC 60811-100:2012. La CEI 60811-508:2012 decrit la procedure a suivre pour realiser lessai de pression a temperature elevee, generalement applicable aux melanges thermoplastiques utilises pour les materiaux disolation et de gainage. La CEI 60811-508:2012 annule et remplace lArticle 8 de la CEI 60811-3-1:1985, qui est supprimee. Lensemble des details relatifs aux remplacements figure dans lAnnexe A de la CEI 60811-100:2012. Des modifications techniques importantes ont ete effectuees par rapport a ledition precedente, comme suit: - redefinition des caracteristiques relatives a letuve, en particulier les caracteristiques antivibratoires et le controle de la temperature; - des details supplementaires relatifs aux preparations et aux essais de cables meplats; - des details supplementaires relatifs aux mesures depaisseur et de dimensions.
