Reaction to fire tests - Ignitability of building products subjected to direct impingement of flame - Part 2 : single-flame source test

Le présent document définit une méthode d'essai permettant de déterminer l'allumabilité des produits de construction par incidence directe d'une petite flamme sous éclairement énergétique zéro, en utilisant des éprouvettes soumises à l'essai en position verticale. Les produits qui fondent et se rétractent au contact de la flamme sans s'enflammer sont concernés par le mode opératoire supplémentaire décrit en annexe A.

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!
