The EN ISO 5659-2 standard specifies a method for measuring smoke production from the exposed surface of plastic materials or composites. This test is conducted in a single-chamber setup, where specimens are subjected to specified levels of thermal irradiance in a closed cabinet, with or without the application of a pilot flame. The primary goal is to determine the optical density of the smoke produced.
Key features of the EN ISO 5659-2 standard include:
Applicability: Suitable for conduit segments according to Annex F.4 or flat specimens up to 25 mm in thickness.
Test Environment: Conducted in a controlled, closed cabinet.
Measurement: Focuses on the optical density of smoke, which is crucial for assessing fire safety in various applications such as buildings, trains, and ships.
This standard is essential for R&D in fire safety engineering, providing valuable data on the smoke generation characteristics of different plastic materials.
