BS 06807:2006 pdf download.Methods of test for assessment of the ignitability of mattresses, upholstered divans and upholstered bed bases with flaming types of primary and secondary sources of ignition.
8 Atmosphere for conditioning and testing
8.1 Conditioning
The materials to be tested and the cribs shall be conditioned before the test for at least 72 h in indoor ambient conditions and then immediately before the test for at least 16 h in the following atmosphere:
• temperature: (23 ± 2) °C;
• humidity: (50 ± 5)%.
8.2 Testing
The test shall be carried out in an atmosphere having a temperature between 10 °C and 30 °C and a relative humidity of between 15% and 80%. A means of extracting smoke and toxic gases shall be provided for all such enclosures.
9 Mattress, upholstered divan or upholstered bed base tested with primary ignition sources
9.1 Principle
When mattresses, upholstered divans or upholstered bed bases are used or stored on their own it is necessary and desirable to know their ignitability in their own right (see Note 1). In this test, the item or smaller specimen is tested without bed covers or pillows present, and the ignition sources are positioned on top of and below the test specimen.
9.2 Test specimens
9.2.1 General
The test specimens shall be representative of the components and make-up of the finished item.
9.3.3 When testing an upholstered divan or upholstered bed base from below, the ignition source shall be placed at floor level. The lower edge of the upholstered divan or upholstered bed base shall be supported at the same height above the floor as it would be in normal use. Where there is insufficient clearance between the underside of the upholstered divan or upholstered bed base and the floor, the ignition source shall be placed adjacent to the test specimen.
9.4 Procedure
9.4.1 Sequence of tests
The sequence of tests without bed covers, using the flaming primary
ignition sources 2 to 7 described in BS 5852:2006, shall be as follows:
• 2 butane gas flame;
• 3 butane gas flame;
• 4 pine wood crib;
• 5 pine wood crib;
• 6 pine wood crib;
• 7 pine wood crib.
9.4.2 Preparation
9.4.2.1 Ensure that the means of extinguishing the test specimens are close to hand (see 6.2).
9.4.2.2 Place the test specimen on the test rig, upholstered divan or upholstered bed base and carry out the test within 5 mm of removal of the test specimen from the conditioning atmosphere (see 8.1).
9.4.3 Butane flame test: ignition sources 2 and 3
9.4.3.1 Light the butane emerging from the burner tube, ajust the gas flow to the rate given in BS 5852 and allow the flow to stabilize for at least 120 s.
9.4.3.2 Position ignition sources 2 and 3 as follows:
a) for a test on top of the test specimen, in the position illustrated in Figure 3a);
b) for a test below the test specimen, in the position illustrated in Figure 3a) and Figure 3b) at the distance below the test specimen given in Table 1 for mattresses, or at floor level for upholstered divans and upholstered bed bases.
9.4.3.3 Place the burner tube on top of or below the test specimen as applicable so that the flame is not less than 50 mm from any edge or marks left by any previous test, and simultaneously start the clock.
9.4.3.4 Tests shall not be carried out in coincident positions on top of and below the test specimen.
9.4.3.5 Allow the gas to burn for the time given in BS 5852 then terminate by removing the burner tube from the test specimen.
