BS 8509:2008 pdf free download – Children’s beds for domestic use Safety requirements and test methods.
6.4 Melting behaviour of materials
When tested in accordance with BS EN 7 1-2:2006, 4.4, if the sample has a rate of spread of flame greater than 20 mm/s, there shall be no flaming debris or molten drips.
NOTE A separate sample may be usedfor the tests in 6.2, 6.3 and 6.4.
7 Mechanical hazards — gaps and openings
7.1 Entrapment of head and neck
7.1.1 Completely bound openings
When tested in accordance with 7.1.3, completely bound openings that allow the hip probe to pass completely through shall also allow the head probe to pass completely through the opening.
Completely bound openings that allow the head probe to pass completely through shall conform to the requirement for partially bound, V and irregular shaped openings (see 7.1.2).
7.1.2 Partially bound, V and irregular shaped openings
Partially bound, V and irregular shaped openings shall be constructed so that, when tested in accordance with 7.1.4:
a) portion B of the V and irregular shaped openings template does not enter the opening; or
b) the apex of portion A of the V and irregular shaped openings template contacts the base of the opening.
7.1.3 Test for completely bound openings
7.1.3.1 Insert, the hip probe (see 4.5.2) with the highest force possible up to 30 N into completely bound openings.
7.1.3.2 If the hip probe passes completely through the opening, then insert the head probe (see 4.5.3) into the completely bound opening with a force of up to 5 N.
7.1.4 Test for partially bound, V and irregular shaped openings
7.1.4.1 Position the B portion of the V and irregular shaped openings template (see 4.5.4) between and perpendicular to the boundaries of the opening (see Figure 14 or Figure 15 as appropriate).
7.1.4.2 If the V and irregular shaped openings template can be mserted to a depth greater than the thickness of the template (45 mm), apply the A portion of the V and irregular shaped openings template, so that its centre line is in line with the centre line of the opening. Ensure that the plane of the test template is parallel and applied in line with the opening (see Figure 16). Insert the V and irregular shaped openings template along the centre line of the opening until its motion is arrested by contact with the boundaries of the opening.
7.2 Entrapment of fingers
7.2.1 Requirements
7.2.1.1 When tested in accordance with 7.2.2.1, there shall be no openings between 7 mm and 12 mm, unless the depth of penetration is less than 10 mm (see 7.2.2.2).
7.2.1.2 When tested in accordance with 7.2.2.3, there shall be no openings in mesh or flexible materials that allow the finger probe for mesh to penetrate to the 7 mm diameter section.
7.2.2 Test
7.2.2.1 Mount the 7 mm probe with hemispherical end (see 4.5.5) on the device for exerting force, so that the end can be presented to the opening being tested. Insert the probe with an applied force of up to 30 N into any accessible opening in any possible orientation.
7.2.2.2 If the 7 mm probe enters 10 mm or more, mount the 12 mm probe with hemispherical end (see 4.5.5) on the device for exerting force and insert with an applied force of up to 5 N into any accessible opening in any possible orientation.
