Textile fabrics - Burning behaviour - Determination of ease of ignition of vertically oriented specimens (ISO/DIS 6940:2025)
ISO 6940:2004 specifies a method for the measurement of ease of ignition of vertically oriented textile fabrics and industrial products in the form of single or multi-component fabrics (coated, quilted, multilayered, sandwich constructions, and similar combinations), when subjected to a small, defined flame. This method assesses the properties of textile fabrics in response to flame contact under controlled conditions.

Textiles - Comportement au feu - Détermination de la facilité d'allumage d'éprouvettes orientées verticalement (ISO/DIS 6940:2025)
L'ISO 6940:2004 spécifie une méthode permettant de mesurer la facilité d'allumage des étoffes et produits industriels orientés verticalement par rapport à une flamme définie de petite taille; il peut s'agir d'étoffes simples ou complexes (textiles enduits, ouatés, multicouches, en sandwich et autres structures similaires). Cette méthode permet d'évaluer les propriétés des étoffes en réaction à un contact avec la flamme dans des conditions contrôlées

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
