BS 5867-2 is a British Standard that specifies the test method for determining the flammability characteristics of curtains, drapes, and other window treatments made from fabric. It is specifically focused on assessing the ignitability of these materials when subjected to a small ignition source, such as a match flame.
The standard consists of various tests that evaluate different aspects of flammability. The primary test method outlined in BS 5867-2 involves exposing a fabric sample to a defined ignition source for a specified duration and evaluating its ignition and burning behavior. The test evaluates parameters such as flame spread, afterflame time, and afterglow time.
To perform the flammability test according to BS 5867-2, a specialized flammability tester is required. This tester is designed to simulate a small ignition source and provide controlled conditions for the assessment of fabric flammability. The specific details of the tester can be found in the standard itself.
It's worth noting that adherence to BS 5867-2 is typically a requirement for curtains, drapes, and other window treatments used in commercial or public spaces where strict fire safety regulations are in place. The standard helps ensure that these materials meet certain flammability standards and reduce the risk of fire hazards.
If you are looking to test curtains or drapes for their flammability characteristics, it is advisable to consult the complete standard (BS 5867-2) for detailed test procedures, equipment specifications, and any specific requirements for sample preparation. Additionally, you may need to engage the services of a certified testing laboratory that can conduct the tests in accordance with the standard.
