12、nt (EN 15187:2006) has been prepared by Technical Committee CEN/TC 207 “Furniture”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2007, and conflic
13、ting national standards shall be withdrawn at the latest by April 2007. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finlan

EN 15187:2006 (E) 4 1 Scope This European standard specifies a method for the assessm
15、ent of the effects of light in indoor conditions, by exposure to artificial radiation and applies to rigid surfaces of all finished products regardless of material. It does not apply to finishes on leather and fabrics. The test is intended to be carried out on a part of the finished furniture, but c
16、an be carried out on test panels of the same material, finished in an identical manner to the finished product, and of a size sufficient to meet the requirements of the test. The test should be carried out on unused surfaces. This standard describes the most important parameters, such as the colour
17、change when a surface is exposed and specifies the conditions to be used in the exposure apparatus. The light resistance of a surface can be assessed by using two apparatus as specified in clause 4, one as a reference test method, and the other for in-company testing. 2 Normative references The foll

EN 15187:2006 (E) 7 6 Preparation and conditioning 6.1 Storing and conditioning The test panel shall be kept without direct exposure to light. The test panel shall be stored
30、for not less than four weeks at a temperature not less than 15C and not more than 30C with free circulation of air. Conditioning of the test surface shall begin one week before testing and shall be carried out in air at a temperature of (23 2) C and a relative humidity of (50 5) %. NOTE The conditio
31、ning can be a part of the above four weeks. 6.2 Test surface One test surface shall be prepared. The test surface shall be substantially flat. The test surface shall be taken at least 20 mm from the edge (see Figure 1.a). The minimum size of the test surface is 150 mm x 45 mm (see Figure 1.b). The t
32、est surface shall be carefully wiped with a cleaning cloth, see clause 5.4, before the test.

35、 direct light. Part of the set of blue wool reference and the control section of the test surface (see Figure 1.b, section 1) shall be masked by aluminium foil, according to Figure 1.b, with the high gloss side facing the lamp. This foil shall not be glued to the surface to be exposed. The foil shal
36、l be firmly fixed on the reverse side in order to clearly differentiate between the two zones of the test surface. EN 15187:2006 (E) 9 7.2 Exposure Place the test surface sections 1 and 2 inside the apparatus, and start the exposure. 7.3 Duration Discontinue the exposure when the contrast between th
37、e exposed and unexposed sections of the blue wool reference 6 is equal to grade 4 on the grey scale, as defined in ISO 105-A02. NOTE 1 If necessary, a spectrophotometer can be used, in which case the colour difference E* = 1,7 0,3, is when grey scale grade 4 is reached. NOTE 2 Although the use of bl
38、ue wool references is no longer the preferred method of measuring radiant exposure (see EN ISO 4892-2), and blue wool standards are no longer commercially available in some countries, the method is still in common use. Once sufficient data has been collected, the end-point of the test will be define
39、d by the level of radiant exposure. NOTE 3 The laboratory can use a set of blue wool reference 1 to 8 or blue wool references 5, 6, 7 only. Blue wool references 5 and 7 are included to provide confirmation that blue wool references 6 has degraded to the specified degree of contrast. 8 Assessment of
40、results Immediately after the exposure phase, the test surface shall be kept in the conditioning atmosphere in an area without direct light exposure. After one day and before three days, simultaneously assess the contrast and the colour change using a Day-Light Cabinet with a D65 illuminant source a
41、ccording to the ISO 10526, as follows: Each test surface shall be rated by an experienced observer. In cases of a dispute, three observers shall be required. All observers shall have good colour vision. Viewing distance shall be from 0,25 m to 1,00 m. Compare the two control sections (see Figure 1.b
42、, sections 1 and 3). If they are identical, the results shall be taken from the tested sample (see Figure 1.b, sections 1 and 2). If they are not identical, the result shall be taken from the exposed section and the untested control section (see Figure 1.b, sections 2 and 3). Assess the colour chang
43、e of the test surface by examining the colour change between the exposed and non-exposed sections of the test surface and by comparison to the grey scale (9 step scale according to the ISO 105-A02). In case of three observers, the reported rating for the test surface shall be averaged to the nearest
44、 nominal value. Express the result in relation to the resistance to light of Blue wool standard No. 6 as shown in Table 3. Table 3 Resistance to light Test rating Grey scale Resistance to light Blue wool Standard No.6 4 6 4 6 4 6 EN 15187:2006 (E) 10 NOTE 1 In case of plain colours (only one colour,
45、 without pattern or colour combinations), a colour measurement according to ISO 7724-2 is also permitted. If this additional measurement is carried out, the result and the equipment should be reported. NOTE 2 If it is desired to record the character of the change in colour of the test area, appropri
46、ate qualitative terms may be added as explained in Table 1 of ISO 105-A02:1993. 9 Test report The test report shall include at least the following information: a) reference to this European Standard; b) description of the test panel including relevant data (wherever possible the substrate and the fi
47、nishing system shall be identified, age of the test panels, etc); c) number of replicates if more than one; d) type of exposure apparatus used; e) method of assessment of blue wool scale; f) number of observers; g) control section used for assessment (section 1 or 3); h) colour change expressed acco
48、rding to the grey scale level (e.g. 5 or 4/5) at blue wool N6 and optional the character of colour change; i) resistance to light; j) result and type of geometry of the equipment if a colour measurement is carried out; k) any deviations from this European standard; l) name and address of the test fa
49、cility; m) date of the test.
