EN 1021-1 and EN 1021-2: Fire Testing Standards for Upholstered Furniture
European furniture buyers often encounter EN 1021-1 and EN 1021-2 when sourcing upholstered dining chairs, lounge chairs and contract seating. But what do these standards actually test, and how can buyers use the results when evaluating furniture suppliers?
EN 1021 is a European standard series for assessing the ignitability of upholstered furniture when exposed to two ignition sources: a smouldering cigarette and a simulated match flame.
For furniture importers, wholesalers and Horeca project buyers, understanding these tests helps avoid a common purchasing mistake: assuming that a fire-retardant fabric automatically makes the finished chair fire-resistant.
What Is the EN 1021 Standard?
EN 1021 specifies methods for assessing how upholstered furniture responds to particular ignition sources.
The standard is divided into two parts:
EN 1021-1: Assessment of ignitability using a smouldering cigarette.
EN 1021-2: Assessment of ignitability using a match flame equivalent.
Both tests are relevant to upholstered seating, including dining chairs, sofas, lounge chairs and other seating products with textile coverings and filling materials.
In Germany, buyers may encounter the designation DIN EN 1021, referring to the German adoption of the European standard.
An important distinction: EN 1021 is a testing standard, not a universal fire safety approval for every European furniture application. Applicable requirements depend on the destination market, intended use and relevant regulations or project specifications.
EN 1021-1 vs EN 1021-2: What Is the Difference?
Although both parts assess ignition behaviour, they use different ignition sources.
Test characteristic | EN 1021-1 | EN 1021-2 |
Ignition source | Smouldering cigarette | Match flame equivalent |
Main risk assessed | Smouldering ignition | Small-flame ignition |
Typical test arrangement | Upholstery assembly | Upholstery assembly |
Assessment | Evidence of progressive ignition | Evidence of flaming or progressive ignition |
Buyer relevance | Cigarette ignition resistance | Small open-flame ignition resistance |
Passing one test does not automatically mean that the same upholstery assembly will pass the other.
EN 1021-1: The Smouldering Cigarette Test
EN 1021-1 evaluates whether upholstered furniture materials can resist ignition caused by a smouldering cigarette.
During testing, a specified cigarette is placed against the upholstery assembly under controlled conditions. The assembly is then observed for signs of progressive smouldering or flaming ignition.
For furniture buyers, the test provides evidence of how a particular upholstery combination behaves when exposed to this ignition source.
EN 1021-2: The Match Flame Equivalent Test
EN 1021-2 evaluates the ignitability of an upholstery assembly when exposed to a small gas flame representing a match flame.
The flame is applied under specified conditions, and the assembly is assessed for ignition behaviour.
This test addresses a different ignition scenario from EN 1021-1.
Buyers should therefore confirm whether a project requires one test, both tests or additional fire performance assessments.
Does Fire-Retardant Fabric Mean the Entire Chair Passes EN 1021?
Not necessarily.
One of the most important factors in upholstered furniture fire testing is the interaction between the covering material and the filling beneath it.
A dining chair may contain several materials:
Upholstery fabric
Polyurethane foam
Interlining or barrier materials
Additional padding layers
Seat and backrest support components
The fire performance of a tested assembly can depend on how these materials interact.
For example, a fabric that achieves a favourable result when tested with one foam specification may behave differently when combined with another foam.
This creates a practical sourcing risk.
A supplier might provide an EN 1021 report for an upholstery material, while the finished dining chair uses a different combination of materials.
For B2B furniture buyers, the key question is not simply whether the fabric has been tested, but whether the test evidence is relevant to the actual product being purchased.
Which Furniture Applications Should Buyers Consider?
EN 1021 testing may be relevant to several upholstered seating categories.
Furniture application | Buyer consideration |
Residential upholstered dining chairs | Check destination-market requirements and retailer specifications |
Restaurant dining chairs | Confirm the fire performance specified by the project |
Hotel lounge seating | Review applicable hospitality and local fire safety requirements |
Office and conference chairs | Check commercial seating specifications |
Contract furniture | Verify tender documents and required test evidence |
Commercial furniture projects may specify requirements beyond EN 1021.
Buyers should not assume that passing EN 1021-1 and EN 1021-2 automatically satisfies every hotel, restaurant or public-space fire safety requirement.
EN 1021 vs BS 5852: Are They Interchangeable?
EN 1021 and BS 5852 are both associated with upholstered furniture ignition testing, but they should not be treated as interchangeable.
EN 1021-1 and EN 1021-2 address specified cigarette and match-flame-equivalent ignition sources.
BS 5852 covers methods involving different ignition sources and test arrangements. Some commercial furniture specifications may refer to particular BS 5852 ignition-source levels.
For buyers sourcing furniture for the UK, the applicable requirements must be checked against the relevant regulations, product category and intended use.
An EN 1021 test report alone should not be assumed to demonstrate compliance with UK furniture fire safety legislation.
Why Can Upholstered Furniture Fail Fire Testing?
Fire testing outcomes can be affected by several factors.
1. Upholstery Fabric Composition
Different fibres, fabric constructions and finishes may behave differently when exposed to ignition sources.
2. Foam and Filling Materials
The filling material beneath the upholstery can influence the ignition behaviour of the tested assembly.
3. Changes in Material Specifications
Changing the fabric, foam, interlining or other relevant components may affect whether existing test evidence remains applicable.
4. Production Consistency
A tested sample is only useful for purchasing decisions if the relevant materials and construction are properly controlled during production.
For importers ordering upholstered dining chairs in volume, this makes material specifications and supplier quality control especially important.
How Should European Buyers Check an EN 1021 Test Report?
Before confirming a furniture order, purchasing teams should review the following points:
Test standard: Does the report identify EN 1021-1, EN 1021-2 or both?
Tested materials: Which fabric, foam and other relevant upholstery components were tested?
Test result: Does the report clearly state the outcome and observations?
Sample identification: Can the supplier connect the tested sample to the proposed product?
Material changes: Have any relevant materials changed since testing?
Project requirements: Does the available evidence meet the buyer's specified requirements?
For OEM and ODM furniture projects, these questions should be addressed during sample development rather than after mass production.
What Should Buyers Ask Their Furniture Supplier?
When sourcing upholstered dining chairs or Horeca seating, buyers should request clear information about the proposed upholstery construction and available testing evidence.
Useful questions include:
Can you provide the relevant EN 1021 test reports?
Which upholstery combination was tested?
Does the proposed chair use the same relevant materials?
Can alternative upholstery specifications be developed if additional testing is required?
How are approved materials controlled during production?
These questions help buyers evaluate the supplier's technical understanding and reduce the risk of misunderstandings before shipment.
Frequently Asked Questions
Is EN 1021 mandatory for all furniture sold in Europe?
No. EN 1021 is a European testing standard, but its use is not automatically mandatory for every furniture product sold across Europe. Applicable legal and contractual requirements depend on the market and intended application.
Is EN 1021-1 the same as EN 1021-2?
No. EN 1021-1 uses a smouldering cigarette ignition source, while EN 1021-2 uses a match flame equivalent. The two tests assess different ignition scenarios.
Does an EN 1021 test report cover every fabric colour?
Not automatically. Buyers should check the identification and scope of the tested materials and confirm whether variations are covered by the available evidence.
Can an EN 1021-tested chair be used in a hotel or restaurant?
Potentially, but suitability depends on the requirements applicable to the particular premises and project. EN 1021 results should be evaluated alongside other specified fire safety requirements.
A Practical Approach to Fire Testing and Furniture Sourcing
For European furniture buyers, EN 1021 testing should be part of a broader supplier evaluation process.
Understanding the test method is the first step. Confirming the tested upholstery combination, reviewing reports and controlling material specifications are equally important.
ASKT works with European B2B buyers on dining chair development, upholstery selection and product customisation. For projects with specific fire performance requirements, these requirements should be identified early so that suitable materials and testing arrangements can be evaluated before production.
The objective is straightforward: make furniture sourcing decisions based on clear specifications and relevant test evidence rather than assumptions about fire-retardant materials.
