Plastics — Intumescence properties of PVC materials and products — Test method for the measurement of expansion with the cone calorimeter

Plastiques — Propriétés d'intumescence des matériaux et produits en PVC — Méthode d’essai pour mesurer l’expansion à l’aide d'un calorimètre à cône

Abstract / scope

This document specifies a test method for assessing the expansion of PVC materials and products during their combustion under the effect of heat radiation.

This test method is also applicable to materials and products made from blends and mixtures of PVC with other polymers, such as PVC blended with a copolymer of styrene and acrylonitrile (PVC-SAN).
