European Standards
EN 13823+A1:2022 – SBI – „Reaction to fire tests for building products – Building products excluding floorings exposed to the thermal attack by a single burning item”. The method of fire tests of building materials excluding floorings is presented in European Standard mentioned aboved. List of materials which should be tested via SBI is declared in Decision 2000/147/EC.
The test sample consists of two vertical panels forming a rectangular corner. It is subjected to flames from a burner placed at the bottom of the corner. The flames are generated by burning propane, which provides a thermal power of (30,7±2,0kW).
The properties of the sample are determined over a period of 20 minutes. The parameters characterizing the product are: fire growth rate [FIGRA], total heat release [THR], smoke growth rate [SMOGRA], total smoke production [TSP], lateral (horizontal) flame spread, and falling droplets and particles.
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.
EN ISO 1716: 2018-08 “Reaction to fire tests of products. Determination of gross calorific value (calorific value) ”. The given standard determines the heat of combustion of a material on the basis of combustion of a material sample in an oxygen atmosphere under pressure in a calorimetric bomb which is immersed in water and measuring the temperature increase of this water.
EN ISO 1182: 2020 “Reaction to fire tests of products. Non-flammability test “. The tests according to this standard are carried out in a tubular furnace.
This method has been developed for materials that release a minimal amount of heat during combustion and do not contribute to fire development. In this test, homogeneous materials or essential components of non-homogeneous materials are examined. The test is performed using a tube furnace heated to a temperature of 750°C.
EN ISO 60695-11-10 “Fire hazard testing”
Test for flammability of materials/products exposed to a 50W flame burner. When designing any electrical product, the risk of fire and potential associated hazards must be taken into consideration. Therefore, the objective of component, circuit, and product design, as well as material selection, is to reduce the potential fire risk to an acceptable level under normal operating conditions. This part of the standard specifies laboratory test procedures on a small scale to compare the behaviour of different materials used in electrical products when vertically or horizontally oriented rod-shaped samples are exposed to a small igniting source with a nominal heat power of 50W. This test method determines the linear burning rate or self-extinguishing properties of materials.
These test methods apply to solid and cellular materials with an apparent density greater than 250 kg/m3 as defined in ISO 845.
Method A is the horizontal burning test. Method B is the vertical burning test.
EN ISO 60695-11-20 “Fire hazard testing” Test for flammability of materials/products exposed to a 500W flame burner; commonly known as “UL standard”.
This test method applies solely to solid and cellular materials with an apparent density greater than 250 kg/m3 as defined in ISO 845. The methods do not apply to materials that, due to their thinness, shrink away from the applied flame without igniting.
The described test method provides a classification that can be used for quality assurance, preliminary selection of constituent materials, or to verify the required minimum flame class of materials used in end products.
The test method consists of two small-scale laboratory test procedures aimed at comparing the burning behaviour of different materials used in electrical products. Samples in the form of vertically oriented rods or horizontally oriented plates are exposed to a small flame source with a nominal power of 500W. There are two sample configurations:
- Rectangular rod-shaped samples are used to assess ignitability and burning behaviour.
- Square plate-shaped samples are used to evaluate the resistance of the sample to propagation.
This test method applies only to materials that have been classified as V-0 or V-1 according to IEC 60695-11-10.
