Furniture - Assessment of the ignitability of upholstered furniture - Part 2: Ignition source match flame equivalent

This European Standard specifies a test method to assess the ignitability of material combinations, such as covers and fillings used in upholstered seating, when subjected to a small flame as an ignition source.
The test measures only the ignitability of a combination of materials used in upholstered seating and not the ignitability of a particular finished item of furniture incorporating these materials.

Möbel - Bewertung der Entzündbarkeit von Polstermöbeln - Teil 2: Eine einem Streichholz vergleichbare Gasflamme als Zündquelle

Diese Europäische Norm legt ein Prüfverfahren zur Bestimmung der Entzündbarkeit von Werkstoff-kombinationen wie Bezüge und Füllungen für gepolsterte Sitzmöbel fest, wenn diese einer kleinen Flamme als Zündquelle ausgesetzt sind.
Anhand der Prüfungen wird lediglich die Entzündbarkeit einer Kombination von Werkstoffen bestimmt, die zur Herstellung von gepolsterten Sitzmöbeln verwendet wird, nicht aber die Entzündbarkeit eines bestimmten fertigen Möbelstücks, das aus diesen Werkstoffen besteht.

Ameublement - Evaluation de l'allumabilité des meubles rembourrés - Partie 2: Source d'allumage flamme équivalente à une allumette

La présente Norme européenne spécifie une méthode d’essai permettant d’évaluer l’allumabilité de combinaisons de matériaux, comme les revêtements et les rembourrages utilisés dans les sièges rembourrés, lorsque la source d’allumage à laquelle ils sont exposés est une petite flamme.
Cet essai mesure uniquement l’allumabilité d’une combinaison de matériaux utilisés dans les sièges rembourrés et non l’allumabilité d’un article d’ameublement fini particulier qui incorpore ces matériaux.

Pohištvo - Ocenjevanje vžigljivosti oblazinjenega pohištva - 2. del: Vir vžiga: enakovreden plamenu vžigalice

Standard EN 1021-2 določa preskusno metodo za ocenjevanje vžigljivosti kombinacij materialov, kot so prevleke in polnila, ki se uporabljajo v oblazinjenih sedežih, kadar so podvrženi majhnemu plamenu kot viru vžiga. Preskus meri le vžigljivost kombinacije materialov, ki se uporabljajo v oblazinjenih sedežih, in ne tudi vžigljivosti posameznega dokončanega kosa pohištva, ki vključuje te materiale.

Overview

EN 1021-2:2014 (CEN) is the European test standard for assessing the ignitability of upholstered furniture material combinations when exposed to a small flame equivalent to a burning match. It specifies a standardized test method and apparatus to evaluate how covers, inner covers and fillings used in seating assemblies respond to a match-flame–equivalent gas ignition source. The standard measures the ignitability of the composite materials on the test rig and does not certify the ignition performance of a finished piece of furniture.

Key topics and technical requirements

• Scope and purpose: Test method for material combinations (outer cover, inner cover ≤2 mm, fillings) used in upholstered seating.
• Ignition source: A gas flame designed to be match-flame equivalent (burner tube dimensions and arrangement are specified; a nominal regulator outlet pressure of 2.8 kPa is referenced).
• Test rig and specimen assembly: Hinged steel frames with steel mesh platforms and specified dimensions to represent a stylized seat/back junction. Frames are locked at right angles for testing.
• Test environment: Conduct tests in a non-combustible fume cupboard or a suitable enclosure/room (>20 m3) with controlled airflow (draught-free, extraction recommended).
• Timing and measurement: Clock/stopwatch accuracy to 1 s for test durations (tests include up to 1 hour observations).
• Criteria of ignition:
  • Progressive smouldering - self-propagating non‑flaming oxidation (examples: smouldering to specimen margins, continuing after 1 hour).
  • Flaming ignition - sustained flame behavior (examples: flaming to specimen margins, flaming >120 s after burner removal).
• Health & safety: Operator protection, ventilation, and adequate extinguishing means (water spray, extinguishers, immersion if needed).
• Documentation: Test report details and final examination requirements; informative annexes provide guidance for designers and sample report forms.

Applications and users

Who uses EN 1021-2:2014:

• Furniture manufacturers and component suppliers verifying material combinations for compliance.
• Product designers and specifiers assessing fire risk at the material-selection stage.
• Test laboratories and conformity assessment bodies performing ignitability testing.
• Safety engineers and procurement teams specifying seating for public/commercial environments.

Practical use:

• Screening cover/filling combinations during product development.
• Supporting risk assessments and regulatory conformity for upholstered seating.
• Informing design choices to reduce ignition risk from small open flames (matches, lighters).

(6,5 ± 0,1) mm internal diameter and (200 ± 5) mm in length] is connected by flexible tubing to a cylinder containing butane via a flowmeter, fine control valve, on-off valve (optional) and cylinder regulator providing outlet pressure of nominal 2,8 kPa1) ). Where tubing of these dimensions is not readily available, stainless steel tubing of approximately similar dimensions may be used provided that the 50 mm length at the ‘flame’ end of the tube is machined to the given size. To facilitate positioning the tube, a suitable handle may be fitted to it at least 100 mm from the flame end of the burner tube. A calibrated flow metre shall supply butane gas at a flow rate of (45 ± 2) ml/min at (25 ± 3) °C. The flexible tubing connecting the output of the flowmeter to the burner tube shall be 2,5 m to 3 m in length with an internal diameter of (7 ± 1) mm. NOTE 2 This corresponds to a flame height of approximately 35 mm. 6.5 Gas flow control It is essential that the rate of supply of gas to the burner tube conforms to the flow rate specified. Some difficulties have been reported with the supply and measurement of the gas, particularly where the gas cylinder has, of necessity, to be stored in an environment cooler than the defined test conditions and/or at some distance from the test rig. In these cases, and other situations where difficulties occur, it is important that there should be sufficient length of tubing inside the controlled environment (10 °C to 30 °C) to ensure that the gas equilibrates to the required temperature before flow measurement. One way to assist this is to pass the gas (before flow measurement) through a metal tube immersed in water maintained at a constant temperature such that the gas temperature at entry to the flow metre is (25 ± 3)°C, so that flow corrections for temperature variations can be avoided. Great care also needs to be exercised with the measurement and setting of the flow rate o
