A European standard, BS 5852-2, provides test methods for assessing the flammability of material combinations when exposed to flaming sources of ignition, such as butane flames or wooden cradles.
This standard is used to evaluate the flammability properties of assembled materials, such as covers and paddings used in upholstered seats, when exposed to gas flames and small wooden cradles with different ignition sources.
Essentially, all elements of indoor upholstered furniture must comply with applicable legal regulations. These regulations explain what technical fire methods to use for a piece of furniture or its components, specify requirements and warn how often tests should be done. In some cases, these regulations impose requirements beyond those specified in the referenced test standards.
Tests in accordance with the BS 5852-2 standard are performed in a test cabinet with calibrated airflow. The cover fabric and padding are put on a test setup to create a small sofa with a 90 degree angle between the seat and back.
Six different ignition sources are used in the tests. Ignition sources numbered 2-3 are gas flames, and ignition sources numbered 4-7 are wooden cradles. The higher the number, the larger the gas flame or cradle.
During the cigarette test, the test assembly is allowed to burn for 30 minutes from the start of the test, and for 60 minutes for wooden cradles. The fire source is not kept longer than this time. The test assembly is also not allowed to char more than 100 mm in any direction upwards from the ignition source.
In short, the BS 5852-2 standard is mainly applied for the following material combinations:
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides flammability testing services with flame welds in upholstered composite materials for seating purposes within the scope of BS 5852-2 standard, with its trained and expert staff and advanced technological equipment.
