1.       BS 5852 Fire test of upholstered seating Standard Title

 

BS 5852-2006: Methods of test for assessment of the ignitability of upholstered seating by smouldering and flaming ignition sources

 

2.       BS 5852 Fire test of upholstered seating Standard Brief

The standard is used to assess the ignitability of material combinations, such as covers and fillings used in upholstered seating, when subjected to a smouldering cigarette and a match flame equivalent as ignition source.

In United Kingdom all items of domestic upholstered furniture must meet the “Furniture and Furnishings (Fire) (Safety) Regulations 1988” with amendments. BS 5852:Part 1 and BS 5852:Part 2 has been withdrawn by BSI (British Standards Institution) but are still used as the regulations mentioned above refers to the standards.

 

3.  BS 5852 Fire test of upholstered seating Products Scope

 

This British Standard describes methods for assessing the ignitability of single material combinations:

Covers used in upholstered seating

Fillings used in upholstered seating

Complete items of seating

 

4.    BS 5852 Fire test of upholstered seating Test Method

 

The tests are performed in a test cabinet with a calibrated air flow. The cover fabric and the filling are put in a test rig to create a small sofa with a 90o angle between seat and back. The ignition sources are located in the junction between seat and back. There are six different ignition sources, numbered 2-7. ignition sources 2-3 are gas flames and ignition sources 4-7 are wooden cribs (the higher number the larger gas flame/crib).

 

During the gas flame tests the test assembly is not allowed to smoulder for more than 30 minutes from the start of the test (60 minutes for wooden cribs). The test assembly is not allowed to show evidence of charring more than100 mm in any direction apart from upwards from the ignition source. The gas flames are removed after 40 seconds (ignition source 2) or 70 seconds (ignition source 3). No flaming is allowed to continue for more than 120 seconds after removal of the burner tube. No flaming is allowed to continue for more than 10 minutes after start of the test with ignition source 5 (13 minutes with ignition source 6-7).
