Method of test for resistance to fire of unprotected small cables for use in emergency circuits

This European Standard specifies the test method for cables designed to have intrinsic resistance to fire and intended for use as emergency circuits for alarm, lighting and communication purposes. This European Standard is applicable to cables for emergency circuits of rated voltage not exceeding 600 V/1 000 V, including those of rated voltage below 80 V and optical fibre cables. This European Standard includes details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to electric power and control cables with rated voltage up to and including 600 V/1 000 V. Details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to copper data and telecom cables and optical cables are given in the relevant standards of CLC/TC 46X and CLC/TC 86A. The test method is limited to cables with an overall diameter not exceeding 20 mm. The test method is based on the direct impingement of flame from a propane burner giving a constant temperature attack of a notional 842 °C. It is intended to be used for cables for emergency circuits suitable for alarm, emergency lighting and communication. NOTE When the test method is used in support of EN 13501-3, it only applies to cables of less than 20 mm diameter, and, for metallic conductor cables, to those with conductor sizes up to and including 2,5 mm². For optical cables, only the less than 20 mm diameter limit applies. This European Standard includes (Annex B) the field of direct application and rules for extended application of test results (EXAP). Details regarding classification using data from this test are given in EN 13501-3 . Information regarding classification is given in Annex D. This European Standard also includes informative guidance (Annex E) on a means of applying a water spray to the cable during the test. Such a requirement may be a feature of particular product standards.

Metoda preskušanja požarne odpornosti nezaščitenih malih kablov v zasilnih tokokrogih

Ta evropski standard določa preskusne metode za kable, ki so sami po sebi odporni proti požarom in namenjeni za uporabo kot zasilni tokokrogi za namene zvočnih opozoril, razsvetljave in komunikacije.
Ta evropski standard velja za kable zasilnih tokokrogov, katerih nazivna napetost ne presega 600 V/1 000 V, vključno s tistimi z nazivno napetostjo pod 80 V, in kable z optičnimi vlakni. Ta evropski standard vključuje podrobnosti o določeni točki odpovedi, napravi za preverjanje neprekinjenosti, preskusnem vzorcu, preskusnem postopku in poročilu o preskusu v zvezi z električnimi napajalnimi in krmilnimi kabli z nazivno napetostjo do in vključno z 600 V/1 000 V. Podrobnosti o določeni točki odpovedi, napravi za preverjanje neprekinjenosti, preskusnem
vzorcu, preskusnem postopku in poročilu o preskusu v zvezi z bakrenimi podatkovnimi in telekomunikacijskimi kabli so
podane v ustreznih standardih odborov CLC/TC 46X in CLC/TC 86A. Preskusna metoda je omejena na kable, katerih skupni premer ne presega 20 mm. Preskusna metoda temelji na neposrednem stiku s plamenom iz propanskega gorilnika, s katerim se predmet preskusa izpostavi ocenjeni konstantni temperaturi 842 °C. Namenjena je uporabi za kable v zasilnih tokokrogih za namene zvočnih opozoril, razsvetljave in komunikacije.
OPOMBA: Če se preskusna metoda uporablja kot podpora standardu EN 13501–3, se uporablja samo za kable s premerom, manjšim od 20 mm, in za kable s kovinskimi vodniki z velikostjo vodnikov do in vključno z 2,5 mm2. Preskusna metoda se uporablja tudi za optične kable s premerom, manjšim od 20 mm.
Ta evropski standard vključuje (dodatek B) neposredno uporabo in pravila za razširjeno uporabo rezultatov preskusa (EXAP). Podrobnosti glede razvrščanja v razrede na podlagi podatkov preskusa so podane v standardu EN 13501-3 1). Informacije o razvrščanju v razrede so podane v dodatku D.
Ta evropski standard vsebuje tudi informativne smernice (dodatek E) glede pršenja kabla z vodo med preskusom. Ta zahteva je lahko del standardov za določene proizvode.
