Types of tests
FIRE-LAB as research and accredited laboratory is able to perform tests presented below:
PN-EN 13823+A1:2014 – SBI – „Reaction to fire tests for building products – Building products excluding floorings exposed to the thermal attack by a single burning item”.
European Standard mentioned above specifies a method of test for determining the reaction to fire performance of construction products excluding floorings, and excluding products which are indicated in Delegated Regulation (EU) 2016/364, when exposed to thermal attack by a single burning item (SBI). This document has been developed to determine the reaction to fire performance of essentially flat products. The treatment of some families of products, e.g. linear products (pipes, ducts, cables etc.), can need special rules.
The purpose of the SBI test is to determine classification parameters such as:
- FIGRA – Fire Growth Rate – maximum of the quotient of heat release rate from the specimen and the time of its occurrence using a THR-threshold of 0,2 and 0,4 MJ,
- SMOGRA – Smoke Growth Rate – maximum of the quotient of smoke production rate from specimen and the time of its occurence,
- TSP – Total Smoke Production – total some production from specimen in the first 600s of exposure to main burner flames,
- THR600s – Total Heat Release – total heat release from specimen in the first 600s of exposure to the main burner flames,
- LFS – Lateral Flame Spread – lateral flame spread on the long specimen wing.
Measured parameters are a base to determine one of the few possible class of reaction to fire. SBI tests are used for classification of classes A2, A2L,B, BL, C, CL, D i DL .
PN-EN ISO 11925:2:2013 and EN ISO 11925-2:2020 – “Reaction to fire test – Ignitability of products subjected to direct impingement of flame – Part 2: Single-flame source test (ISO 11925-2:2020)”.
This fire test method has been developed to define reaction to fire performance of products. The method specifies a test for determining the ignitability of products by direct small-flame impingement under zero impressed irradiance using vertically oriented test specimens.
Although the method is designed to assess ignitability, this is addressed by measuring the spread of a small flame up the vertical surface of a specimen for either 15s or 30s. The determination of the production of flaming droplets/particles depends on whether or not the filter paper placed beneath the specimen ignites.
