UNE-EN 1794-3:2016

This European Standard is to give authorities, designers and specifiers information with respect to reaction to fire, smoke density and toxic fumes of materials used in noise reducing devices. The combination of brushwood fire test, smoke density test and test for toxic fumes give in general enough safety information. This European Standard allows also for more stringent requirements for those situations when a higher level of safety is needed. For noise reducing devices, this European Standard gives a method how to handle substantial components of non-homogeneous products (as defined in EN 13501-1 and ISO 5659-2) and how to handle non-homogeneous products and in which cases the influence of non-substantial components on the total result of the classification may be neglected. The following effects are of interest: ignitability, burning droplets, smoke growth rate, smoke density, toxic fumes.
