CAN/CGSB-4.2 No 27.6 Méthodes pour épreuves textiles Résistance à l’inflammation — Essai à la tablette de méthénamine des revêtements de sol textiles

1 Scope

This method assesses the combustion resistance of mattresses when in contact with a lighted cigarette. This method covers the resistance of mattresses to ignition only by a burning cigarette and does not relate to their resistance to any other source of ignition or fire condition.

The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This standard does not purport to address all the safety aspects associated with its use.
Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither
assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed.

2 Principle

The surface of a mattress assembly is exposed to a lighted cigarette as the standard ignition source in a draftprotected environment. Individual specimens are assessed by observing the maximum distance of charring or
melting on the specimen surface in any horizontal direction from the nearest point of the original location of the cigarette and by determining whether combustion
