Railway fixed equipment. Halogen free cables for signalling and warning alarm used in underground railway networks.

La présente norme définit les caractéristiques, les essais ainsi que les conditions d'homologation et de surveillance de la qualité de fabrication des câbles affectés à la signalisation et à la commande d'avertisseur d'alarme dont les éléments, entourant l'âme conductrice, sont exempts de composés halogénés et soufrés au sens de la présente norme. Ces câbles présentent un comportement amélioré au feu en réduisant les risques d'incendie, par leur caractère de "non propagation", et en limitant les conséquences d'incendie, par leur propriété d'émettre peu de fumée et de gaz toxiques.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

  • mandatory clauses to satisfy,
  • non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
