For compliance with the standard both the definitive requirements specified throughout the standard and the following documented item shall be satisfied. a) If testing of sign face material is to be carried out with the sample attached to a substrate other than 3 mm aluminium sheet (see 5.1.2). 5 Sign face materials 5.1 Sampling 5.1.1 Test samples Samples for performance testing shall be selected randomly, e.g. in accordance with one of the sampling procedures given in the BS 6001 and BS 6002 series of standards, and shall be representative of the normal production of the sheeting materials to be tested. NOTE Guidance on the selection of sampling procedures from BS 6001 and BS 6002 is given in BS 6000. 5.1.2 Mounting of samples If it is necessary for the material under test to be mounted on a substrate, the material to be tested in accordance with this standard shall be applied to 3 mm aluminium sheet conforming to BS EN 485-1 or other agreed substrate in accordance with the material manufacturer’s instructions [see 4.2a)]. Any protective coatings required by the material manufacturer shall be applied in accordance with the manufacturer’s instructions. 5.2 Visual performance 5.2.1 Chromaticity 5.2.1.1 Daylight chromaticity 5.2.1.2 Non-retroreflective signs When tested in accordance with BS EN 12899-1:2001, 5.2.1.1, the chromaticity and the luminance factor shall conform to BS EN 12899-1:2001, Table 3. 5.2.1.2.1 Retroreflective sign face materials 6.2.1.2.1.1 Glass bead When tested in accordance with BS EN 12899-1:2001, 5.2.1.2, the chromaticity and the luminance factor shall conform to BS EN 12899-1:2001, Table 5. 6.2.1.2.1.2 Microprismatic When tested in accordance with BS 8408:2005, 5.2.1.1, the chromaticity and the luminance factor for non-fluorescent microprismatic material shall conform to BS 8408:2005, Table 2. NOTE The chromaticity boxes for non-fluorescent...
