EN 13823：Reaction to Fire Tests for Building Products - Bulding Products Excluding Floorings Exposed to the Thermal Attack by a Single Burning Item
Abstract摘要
The Single Burning Item test can be considered as the backbone of the Euroclass system for building products. The test results are required for a classification D - B (combined with test results from EN 11925-2), for a classification A2 (combined with test results from EN ISO 1716), and sometimes for a classification A1.
The specimen is exposed to a diffusive flame of 30 kW. Combustion gases are collected by an exhaust hood for analysis. This gas analysis makes it possible by oxygen depletion to calculate heat release rate from the specimen. Smoke production is assessed by measuring attenuation of a light beam by smoke in the exhaust duct. The burning behaviour of the specimen is observed for flame spread, and the occurrence of burning particles and droplets.
