Cables of rated voltages up to and including 450/750 V and having thermoplastic insulation - Part 15: Single core cables, insulated with halogen-free thermoplastic compound, for fixed wiring
This Part 15 details the particular specifications for single-core non-sheathed cables for fixed wiring at rated voltages up to and including 450/750 V, insulated with halogen-free thermoplastic compound and having low emission of smoke and corrosive gases when exposed to fire. For cables rated at 450/750 V there are two types, Type 1 and Type 2. Type 2 cables are required to meet a more severe test for resistance to flame propagation (EN 50266-2-4) than Type 1, and have particular suitability for installation in bunches (see also Annex C). The maximum permissible conductor temperature is 70 C. All cables shall comply with the appropriate requirements given in Part 1 of HD 21 and with the particular requirements of this Part 15. NOTE 1 The overall dimensions of cables in HD 21.15 S1 have been calculated in accordance with EN 60719. NOTE 2 Low emission of smoke is checked in accordance with EN 61034-2. Low emission of corrosive gases is checked as part of the check for absence of halogens (see Annex A).
Starkstromleitungen mit thermoplastischer Isolierhülle fur Nennspannungen bis 450/750 V - Teil 15: Halogenfreie Aderleitungen mit thermoplastischen Werkstoffen für feste Verlegung
Dieser Teil 15 des HD 21.15 S1 ist die Bauartnorm für Aderleitungen für die feste Verlegung mit Nennspannung bis 450/750 V, isoliert mit halogenfreiem thermoplastischen Werkstoff, der im Brandfall nur geringe Mengen von Rauch und korrosiven Gasen abgibt. Für Leitungen mit 450/750 V Nennspannung stehen zwei Bauarten, Typ 1 und Typ 2 zur Verfügung. Typ 2 ist dafür ausgelegt härtere Prüfanforderungen bezüglich Flammausbreitung (EN 50266-2-4), im Vergleich mit Typ 1, zu bestehen und ist speziell für die Installation in Bündeln geeignet. (Siehe auch Anhang C). Die maximal zulässige Temperatur am Leiter beträgt 70 °C. Alle Leitungen müssen den betreffenden Anforderungen des Teils 1 von HD 21 und dieser Bauartnorm entsprechen. ANMERKUNG 1 Die Außenmaße der Leitungen nach HD 21.15 S1 sind in Übereinstimmung mit EN 60719 berechnet worden. ANMERKUNG 2 Geringe Rauchentwicklung wird nach EN 61034-2 geprüft. Der Nachweis der Abgabe geringer Mengen von Rauch und korrosiven Gasen erfolgt nach Anhang A.
Conducteurs et câbles isolés avec des matériaux thermoplastiques de tension assignée au plus égale à 450/750 V - Partie 15: Monoconducteurs pour installation fixe, isolés avec un mélange thermoplastique sans halogène
La présente Partie 15 précise les spécifications particulières applicables aux câbles monoconducteurs non gainés, pour installations fixes, de tension assignée jusqu’à et y compris 450/750 V, ayant une enveloppe isolante en matériau thermoplastique sans halogène et ayant un faible dégagement de fumée et de gaz corrosifs lors d’un incendie. Pour les câbles de tension assignée 450/750 V il y a deux types, Type 1 et Type 2. Les câbles de Type 2, qui conviennent particulièrement pour l’installation en nappe, (voir aussi Annexe C), sont conçus pour répondre à un essai plus sévère de résistance à la propagation de la flamme (EN 50266-2-4) que ceux du Type 1. La température maximale admise sur l’âme est de 70 °C. Tous les câbles doivent répondre aux prescriptions appropriées indiquées dans la Partie 1 du HD 21 et aux prescriptions particulières le concernant figurant dans la présente Partie 15. NOTE 1 Les dimensions extérieures des câbles dans ce HD 21.15 S1 ont été calculées conformément à la EN 60719. NOTE 2 Le faible dégagement de fumée est vérifié selon la EN 61034-2. Le faible dégagement de gaz corrosifs est vérifié et fait partie intégrante de la vérification de l’absence d’halogènes (voir Annexe A).

The maximum permissible conductor temperature is 70 °C.
All cables shall comply with the appropriate requirements given in Part 1 of HD 21 and with
the particular requirements of this Part 15.
NOTE 1 The overall dimensions of cables in HD 21.15 S1 have been calculated in accordance with EN 60719.
NOTE 2 Low emission of smoke is checked in accordance with EN 61034-2. Low emission of corrosive gases is
checked as part of the check for absence of halogens (see Annex A).
