Electric cables - Extended application of test results for reaction to fire
TThis Technical Specification gives the procedure and rules for extended application of results of tests carried out according to the test methods described in EN 50399, EN 60332 1 2 and EN 61034 2. The EXAP rules described apply to EN 50399 test results used for classification in classes B2ca,Cca and Dca, additional smoke production classes s1, s2 and s3 and flaming droplets/particles, to EN 60332 1 2 test results used for classification in classes B2ca,Cca, Dca and Eca and to EN 61034 2 test results used for classification in classes s1a and s1b. Cables of diameter 5,0 mm and less should be tested as bundles according to EN 50399 and are excluded from these rules. Bundled cables are not included in the EXAP rules applying to EN 50399 test results. The rules apply to circular and non-circular cables provided that they fall within the scope of the relevant test method. A specific EXAP rule has been developed for the most common generic power cable families and optical fibre cables. A general EXAP rule has been developed for any power cable families. The general EXAP rule is not applicable to communication or optical fibre cables. NOTE 1 Multicore power cables with more than 5 cores are sometimes referred to as control cables with a rated voltage but for the purposes of this standard are considered as power cables. The general EXAP rule may be applied in the case of hybrid cables provided that the conditions of 6.1 are fulfilled. The use of the specific EXAP rule gives benefit in the lower number of cables to be tested for a range of cable constructions (product family). An EXAP is only possible when cables belong to a defined family as defined in this Technical Specification. NOTE 2 No EXAP procedure and rules have been developed in respect of the results of tests carried out according to the test method described in EN 60754–2. As the parameters (pH and conductivity) for each cable in a family are determined based upon calculation using material test results, this is considered as a matter of direct application. Material test results taken from any one sample of finished cable from a family are sufficient to calculate the parameters for each cable in the family.
Erweiterte Anwendung von Prüfergebnissen bezüglich Brandverhalten
Diese Technische Spezifikation gibt die Verfahren und Regeln wieder für die erweiterte Anwendung von Ergebnissen aus Prüfungen, die nach den in EN 50399, EN 60332 1 2 und/oder EN 61034-2 beschriebenen Prüfverfahren durchgeführt wurden. Die hierin beschriebenen EXAP-Regeln gelten für nach EN 50399 erhaltene Prüfergebnisse für die Einstufung in die Klassen B2ca, Cca und Dca sowie die zusätzlichen für die Rauchentwicklung geltenden Klassen s1, s2 und s3 und bren¬nendes Abtropfen/Abfallen, für nach EN 60332-1-2 erhaltene Prüfergebnisse für die Einstufung in die Klassen B2ca, Cca, Dca und Eca und für nach EN 61034-2 erhaltene Prüfergebnisse für die Einstufung in die Klassen s1a und s1b. Kabel und Leitungen mit einem Durchmesser von bis zu 5,0 mm sollten als Bündel nach EN 50399 geprüft werden und sind von diesen Regeln ausgenommen. Kabel- und Leitungsbündel nach Anwendung der EN 50399 Prüfergebnisse fallen nicht unter die EXAP-Regeln. Die Regeln gelten für runde und nichtrunde Kabel und Leitungen vorausgesetzt sie fallen in den Anwendungsbreich der jeweiligen Prüfmethode. Für die gebräuchlichsten Familien von Starkstromkabeln und -leitungen und Glasfaserkabeln wurde eine spezielle EXAP-Regel erarbeitet. Darüber hinaus wurde eine allgemeine EXAP-Regel entwickelt, die sich auf alle Familien von Starkstromkabel- und -leitungen anwenden lässt. Die allgemeine EXAP-Regel gilt nicht für Kommunikationskabel oder Glasfaserkabel. ANMERKUNG 1 Mehradrige Starkstromkabel und -leitungen mit mehr als 5 Adern werden manchmal auch als Steuerkabel mit einer Nennspannung bezeichnet, werden aber für die Anwendung dieser Norm als Starkstromkabel und –leitungen angesehen. Die allgemeine EXAP-Regel kann auf Hybridkabel angewendet werden vorausgesetzt, dass die Bedingungen aus 6.1 erfüllt sind. Für Kommunikationskabel und Glasfaserkabel wurde bis zum Zeitpunkt der Veröffentlichung dieser TS keine EXAP-Regeln entwickelt. Die Anwendung der speziellen EXAP-Regel hat den Vorteil, dass für eine bestimmte Gruppe von Kabel¬- und Leitungsbauarten (Produktfamilie) jeweils eine geringere Anzahl an Kabeln geprüft werden muss. Eine Anwendung der EXAP-Regeln ist nur dann möglich, wenn die betreffenden Kabel zu einer bestimmten Familie nach der Definition in der vorliegenden Technischen Spezifikation gehören. ANMERKUNG 2 Es wurden kein EXAP-Verfahren und Regeln in Bezug auf die Ergebnisse aus Prüfungen entwickelt, die nach der in EN 60754-2 beschriebenen Prüfmethode durchgeführt werden. Da die Parameter (pH-Wert und Leitfähigkeit) jedes Kabels oder jeder Leitung einer Familie auf der Grundlage von Berechnungen mittels Ergebnissen aus Materialprüfungen, ermittelt werden, können diese Ergebnisse prinzipiell direkt angewendet werden. Für die Berechnung der Parameter von Kabeln in einer Familie sind die Ergebnisse aus Materialprüfungen eines Musters eines fertig produzierten Kabels aus der Familie ausreichend.
Câbles électriques - Application étendue des résultats d'essai pour la réaction au feu
La présente Spécification technique donne les procédures et règles relatives à l'application étendue des résultats d'essais réalisés selon les méthodes d'essai décrites dans l'EN 50399, l'EN 60332 1 2 et l'EN 61034 2. Les règles d’EXAP décrites s'appliquent aux résultats d'essai de l'EN 50399 utilisés pour le classement en classes B2ca, Cca et Dca, en classes supplémentaires d'émission de fumée s1, s2 et s3 et de particules/gouttelettes enflammées, de l'EN 60332 1 2 utilisés pour le classement en classes B2ca,Cca, Dca et Eca et de l'EN 61034 2 utilisés pour le classement en classes s1a et s1b. Il convient que les câbles de diamètre inférieur ou égal à 5,0 mm soient soumis à essai assemblés en faisceau, conformément à l'EN 50399. Les câbles en faisceau ne sont pas inclus dans les règles d’EXAP s'appliquant aux résultats d'essai de l'EN 50399. Les règles s'appliquent aux câbles circulaires et non circulaires, sous réserve qu'ils entrent dans le domaine d'application de la méthode d'essai correspondante. Une règle d’EXAP spécifique a été développée pour les familles génériques de câbles d'énergie les plus courantes et les câbles à fibres optiques. Une règle d’EXAP générale a été développée pour toutes les familles de câbles d'énergie. La règle d’EXAP générale ne s'applique pas aux câbles de communication ou aux câbles à fibres optiques. NOTE 1 Les câbles d'énergie multiconducteurs possédant plus de 5 conducteurs sont parfois appelés câbles de commande à tension assignée, mais pour les besoins de la présente Spécification technique, ils sont considérés comme des câbles d'énergie. La règle d’EXAP générale peut être appliquée dans le cas des câbles hybrides, sous réserve que les conditions de 6.1 soient satisfaites. L'utilisation de la règle d’EXAP spécifique présente un avantage pour un faible nombre de câbles à soumettre à essai faisant partie d'une gamme de câbles de différentes constructions (famille de produits). Une EXAP n'est possible que lorsque les câbles appartiennent à une famille définie, comme cela est précisé dans la présente Spécification technique. NOTE 2 Aucune procédure ni règle d’EXAP n'a été développée en fonction des résultats des essais réalisés conformément à la méthode d'essai décrite dans l'EN 60754-2. Les paramètres (pH et conductivité) de chaque câble d'une famille étant déterminés en fonction des calculs reposant sur les résultats des essais de matériau, ils sont considérés comme une application directe. Les résultats des essais de matériau provenant d'un échantillon de câble d'une famille sont suffisants pour calculer les paramètres pour chaque câble de la famille.
Električni kabli - Razširjena uporaba rezultatov preskusov odziva na ogenj
Ta tehnična specifikacija določa postopek in pravila za razširjeno uporabo rezultatov preskusov, izvedenih v skladu s preskusnimi metodami iz standardov EN 50399, EN 60332 1 2 in EN 61034 2.
Opisana pravila razširjene uporabe se uporabljajo za rezultate preskusov iz standarda EN 50399, ki se uporabljajo za klasifikacijo v razredih B2ca, Cca in Dca, dodatnih razredih nastajanja dima s1, s2 in s3 ter gorečih kapljic/delcev, za rezultate preskusov iz standarda EN 60332 1 2, ki se uporabljajo za klasifikacijo v razredih B2ca, Cca, Dca in Eca, ter za rezultate preskusov iz standarda EN 61034 2, ki se uporabljajo za klasifikacijo v razredih s1a in s1b.
Kabli premera 5,0 mm in manj morajo biti preskušeni v snopih v skladu s standardom EN 50399 in so izvzeti iz teh pravil. Kabli v snopu niso zajeti v pravilih razširjene uporabe, ki se uporabljajo za rezultate preskusov iz standarda EN 50399.
Pravila se uporabljajo za krožne in nekrožne kable pod pogojem, da ti spadajo na področje uporabe ustrezne preskusne metode.
Za najpogostejše splošne družine napajalnih kablov in optične kable je bilo pripravljeno posebno pravilo razširjene uporabe. Za vse družine napajalnih kablov je bilo pripravljeno splošno pravilo razširjene uporabe. Splošno pravilo razširjene uporabe se ne uporablja za komunikacijske ali optične kable.
OPOMBA 1: Večjedrni napajalni kabli z več kot 5 jedri se včasih imenujejo krmilni kabli z nazivno napetostjo, vendar se za namene tega standarda obravnavajo kot napajalni kabli.
Splošno pravilo razširjene uporabe se lahko uporablja v primeru hibridnih kablov, če so izpolnjeni pogoji iz točke 6.1.
Uporaba posebnega pravila razširjene uporabe omogoča manjše število kablov, ki jih je treba preskusiti, za več konstrukcij kablov (družina proizvodov).
Razširjena uporaba je mogoče le, kadar kabli pripadajo določeni družini, kot je opredeljeno v tej tehnični specifikaciji.
OPOMBA 2: V zvezi z rezultati preskusov, izvedenih v skladu s preskusnimi metodami, opisanimi v standardu EN 60754–2, niso bili izdelani nobeni postopki ali pravila razširjene uporabe. Ker se parametri (pH in prevodnost) za vsak kabel v družini določajo na podlagi izračuna z rezultati preskusov materialov, se to obravnava kot predmet neposredne uporabe. Za izračun parametrov za posamezen kabel v družini zadoščajo rezultati preskusov materialov, izvedenih na katerem koli vzorcu dokončanega kabla iz družine.

This document (CLC/TS 50576:2016) has been prepared by CLC/TC 20 “Electric cables”.
The following date is proposed:
· latest date by which the existence of (doa) [2017-04-10]
this document has to be announced
at national level
This document supersedes CLC/TS 50576:2014.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association.
This document is meant to be used in conjunction with EN 50575 in order to evaluate the reaction to
fire performance of power, control and communication cables.
NOTE For the purposes of this Technical Specification, the term 'electric cables' also covers optical fibre
cables.
Introduction
The original project “CEMAC – CE marking of cables” was carried out over a three year period. It
brought together cable manufacturers, research and testing laboratories, and research establishments
in creating the technical background and developing rules and procedures for extended application of
test results (EXAP). More than 200 tests to EN 50399 on more than 100 cables were carried out as
part of the project. The final report [1] was published in 2010 and the EXAP rules and procedures
developed by the CEMAC project have been used as the basis for this Technical Specification.
A specific EXAP procedure and rules based on the use of safety margins and a cable parameter
derived from the extensive CEMAC tests was developed for the most common generic types of power
cables used in the European market.
A general EXAP procedure and rules based upon a statistical treatment of the actual test results
obtained from a cable family was also developed for any power cables. However, the use of this
general procedure and rules will generally require more tests to be carried out than the use of the
specific procedure and rules.
Since the CEMAC project report was completed in 2010, the project has been extended to further
investigate the performance of optical fibre cables and rules and procedures developed for extended
application of test results for these products. An additional report [2] was published in 2015 and the
EXAP rules and procedures developed by the further CEMAC project work have been used as the
basis for the 2016 revision of this Technical Specification.
General guidance on direct and extended application may be found in CEN/TS 15117 [3].
1 Scope
This Technical Specification gives the procedure and rules for extended application of results of tests
carried out according to the test methods described in EN 50399, EN 60332-1-2 and EN 61034-2.
The EXAP rules described apply to EN 50399 test results used for classification in classes B2 ,C
ca ca
, additional smoke production classes s1, s2 and s3 and flaming droplets/particles, to
and D
ca
,C D and E and to EN 61034-2
EN 60332-1-2 test results used for classification in classes B2
ca ca, ca ca
test results used for classification in classes s1a and s1b.
Cables of diameter 5,0 mm and less should be tested as bundles according to EN 50399. Bundled
cables are not included in the EXAP rules applying to EN 50399 test results.
The rules apply to circular and non-circular cables provided that they fall within the scope of the
relevant test method.
A specific EXAP rule has been developed for the most common generic power cable families and
optical fibre cables. A general EXAP rule has been developed for any power cable families. The
general EXAP rule is not applicable to communication or optical fibre cables.
NOTE 1 Multicore power cables with more than 5 cores are sometimes referred to as control cables with a
rated voltage but for the purposes of this Technical Specification are considered as power cables.
The general EXAP rule may be applied in the case of hybrid cables provided that the conditions of 6.1
are fulfilled.
The use of the specific EXAP rule gives benefit in the lower number of cables to be tested for a range
of cable constructions (product family).
An EXAP is only possible when cables belong to a defined family as defined in this Technical
Specification.
NOTE 2 No EXAP procedure and rules have been developed in respect of the results of tests carried out
according to the test method described in EN 60754–2. As the parameters (pH and conductivity) for each cable in
a family are determined based upon calculation using material test results, this is considered as a matter of direct
application. Material test results taken from any one sample of finished cable from a family are sufficient to
calculate the parameters for each cable in the family.
