Title Electric cables - Fire resistance test for unprotected electric cables (P classification)
Project Number 23694
Abstract/Scope This European Standard specifies a test method to evaluate the maintenance of circuit integrity of electric cables which have intrinsic resistance to fire under fire conditions, in order to classify the electric cable according to EN 13501-3 [2]. The test determines the survival time for circuit integrity of the electric cable when exposed to fire under the conditions of the EN 1363-1 standard time/temperature curve. This European Standard is used in conjunction with EN 1363-1. This European Standard applies to electric power and control cables with rated voltage up to and including 600/1 000 V. The cable is tested in a standardized representative installation condition. The test does not assess the performance of the cable management system. NOTE Optical and data cables could be tested using this method but do not form part of this European Standard as the verification procedures for such cables are still under development. This European Standard includes (Annex A) field of direct application and rules for extended application of test results (EXAP).

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn


(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
