Common test methods for cables under fire conditions - Heat release and smoke production measurement on cables during flame spread test - Test apparatus, procedures, results

EN 50399 specifies the apparatus and methods of test for the assessment of vertical flame spread, heat release, smoke production and occurrence of flaming droplets/particles of vertically-mounted bunched wires or cables, electrical or optical, under defined conditions. NOTE For the purpose of this standard the term "electric wire or cable" covers all insulated metallic conductor cables used for the conveyance of energy or signals. EN 50399 details the apparatus and the arrangement and calibration of the instrumentation to be installed in order to measure the heat release and the smoke production during the test. The combustion gases are collected in a hood above the test chamber and conveyed through an exhaust system, which allows the measurement of heat release rate and smoke production. Test procedures to be used for type approval testing for classification of cables in Euroclasses B1ca, B2ca, Cca and Dca are given. Cable installation on the test ladder and the volume of air passing through the chamber are in accordance with the Commission Decision 2006/751/EC [2] which is reflected in the requirements of this standard. The apparatus described in this standard shall be used in conjunction with that described in EN 60332 3 10.

Skupne preskusne metode za ognjevzdržnost kablov - Meritve oddajanja toplote in nastajanja dima na kablih med preskusom z razpršenim plamenom - Preskusna naprava, postopki, rezultati

EN 50399 določa naprave in preskusne metode za ocenjevanje navpičnega širjenja ognja, oddajanja toplote, nastajanja dima in pojava gorečih kapljic/delcev pri navpično pritrjenih snopih žic ali kablov, električnih ali optičnih, in pod določenimi pogoji.
OPOMBA: Za namene tega standarda izraz »električna žica ali kabel« zajema vse izolirane kovinske prevodniške kable, ki se uporabljajo za prenos energije ali signalov.
EN 50399 podrobno opisuje naprave in postavitev ter kalibracijo instrumentov, ki bodo vgrajeni zaradi merjenja oddajanja toplote in nastajanje dima med preskusom. Zgorevalni plini so zbrani v okrovu nad preskusno komoro in odvedeni skozi izpušni sistem, ki dopušča merjenje ravni oddajane toplote in nastanka dima. Podani so preskusni postopki, ki bodo uporabljeni za homologacijsko preskušanje za klasifikacijo kablov v evrorazrede B1ca, B2ca, Cca in Dca. Postavitev kablov na preskusni lestvi in volumen zraka, ki kroži skozi komoro, sta v skladu z Odločbo Komisije 2006/751/ES [2], ki se odraža v zahtevah tega standarda. Aparati, opisani v tem standardu, se uporabljajo skupaj s tistimi, opisanimi v EN 60332-10.
