EN ISO 5659-2 Plastics - Smoke Production - Determination of Optical Density in a Single Chamber Test

The EN ISO 5659-2 standard, developed by the International Standards Organization (ISO), specifies a method for measuring smoke production from the exposed surface of material or composite samples. Applies to specimens having an essentially flat surface and a thickness not exceeding 25 mm when placed in a horizontal direction and exposed to the specified thermal irradiation levels in a closed cabinet with or without a pilot flame. This test method applies to all plastics.

EN ISO 5659-2 Plastics - Smoke Production - Determination of Optical Density in a Single Chamber Test

It is intended that the optical density values ​​determined by this test are taken as specific to the sample or mounting material in the tested form and thickness and will not be considered as natural, basic properties.

Testing is primarily done in buildings, trains, ships, etc. No basis is provided for estimating the smoke density that can be produced by materials when exposed to heat and flame under other (real) exposure conditions. This test procedure excludes the effect of irritants on the eye.

This test procedure compensates for loss of visibility due to smoke density, which is usually not related to irritant strength.

It is emphasized that smoke production from a material varies according to the radiation level to which the sample is exposed. Results from the method described in this document are based on exposure to specific irradiation levels of 25 kW/m2 and 50 kW/m2.

Among the services provided by our organization within the framework of material testing services, there are also EN ISO 10289 standard tests.
