What is Crib5?

CRIB 5 is a fabric fire treatment for upholstery and must only be used for furnishing and upholstery purposes.

Source 5 (Crib 5) is related to upholstery and furniture coverings, and is related to BS 5852. The crib test uses a plank made from wood that is glued together. The fabrics is attached over the lint, then at bottom and a propane-diol is added. The testing unit is then ignited with a match. To decide whether the test has been passed the fabric and the crib are assessed to see whether there is flaming or smoldering on both the outer cover and the interior material. Assuming it does not ignite or smolder, the material will pass the test as no ignition. Similar tests include Source 0 (smouldering cigarette) and Source 1 (simulated match).
BS 5852:2006 describes the best practice methods to assess the ignitability of single material combinations, such as covers and fillings used in upholstered seating, or complete items of seating.
These tests determine the effects of a smouldering cigarette, or other flaming ignition sources such as burning matches or a four-sheet full-size newspaper. This standard can be used to establish the potential ignitability of components in conjunction with other specified materials.
BS 5852:2006 first looks at the criteria of ignition, and the health and safety of operators. It then explains the various apparatus, before focussing on smouldering ignition sources – such as a cigarette, butane gas flames and flaming wooden cribs. It also looks at ways to test for the ignitability of upholstery composites and complete items of furniture. The standard concludes with a final examination and test report. BS 5852:2006 replaces the older certification standard, BS 5852 – 1990.
