24、ication in practice according to this standard. 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 14618:2005 and the following apply. 3.1 slab for vanity and kitchen tops flat slab which can be obtained from the sawing of a block, directly from moulding
25、 or cut-to-size which form a covering for use in furnishing, fixed to a structure either mechanically or by means of specific adhesives NOTE Rough products are obtained from the sawing of a block, directly from moulding, refining the edges and finishing the surface. The products cut-to-size can be s
26、ubsequently used to manufacture composites whose tolerances and performances do not fall under the responsibility of the producer of the agglomerated stone slab BS EN 15388:2008EN 15388:2008 (E) 5 3.2 dimensions of slab for vanity and kitchen tops length l, width b and thickness d of a slab for use
27、in furnishing. The dimensions are given in the stated sequence in millimetres (see Figure 1) Figure 1 Dimensions of the slab 4 Requirements 4.1 Requirements for geometric characteristics 4.1.1 General All measured values of individual units shall fall within the required tolerances. The measurement
28、shall be performed by a Venier calliper or other suitable apparatus for linear measurements to the nearest 0,1 mm. 4.1.2 Requirements for thickness The thickness shall not deviate from the nominal thickness by more than 1,2 mm. The thickness shall result from an analysis which takes into account the
29、 whole size of the slab. The nominal thickness shall be the result of 3 measurements for each meter of the slab length. Stricter tolerances may be declared by the manufacturer. This is particularly important when the edges of the slabs will be visible. 4.1.3 Requirements for flatness The deviation f
30、rom flatness of the surface shall not exceed 4 mm over the slab length and shall not exceed 2 mm over the slab width. Flatness shall be measured in the middle of the slab using the full length and width (not the diagonals) when the slab is horizontal. 4.1.4 Requirements for length and width of rough
31、 products The length and width shall not deviate from the nominal size by more than given in Table 1. Stricter tolerances may be declared by the manufacturer. BS EN 15388:2008EN 15388:2008 (E) 6 Table 1 Tolerances for length and width Nominal length/width in mm Tolerances From 1850 to 3060 (nominal
32、length) -20 mm / +10 mm From 1250 to 1400 (nominal width) -15 mm / +10 mm For other nominal lengths and widths tolerances shall be calculated proportionally. 4.1.5 Requirements for special shapes (only for cut-to-size products) Pieces of special or irregular shapes shall be checked for compliance wi
33、th the required shape. The permissible tolerance at any point shall be 1,2 mm, which may be measured by using a suitable template. Stricter tolerances may be declared by the manufacturer. 4.2 Requirements for surface finish 4.2.1 General Surface finishes shall extend uniformly to the edges of the sl
34、ab. The uniformity shall be guaranteed on at least 90 % of the total surface of the element Stricter values may be declared by the manufacturer. 4.2.2 Requirements for surfaces after surface finishing Surfaces shall have a regular appearance as a function of the finishing process and shall be worked
35、 to meet the finish declared (e.g. by submission of samples beforehand between the purchaser and supplier). The surface roughness of the visible face can be directly obtained by moulding and to present an aspect structured with relief. Example of the surface finishes are: sandblasted surfaces (obtai
36、ned for example by means of a sandblasting action), fine ground surfaces (obtained for example by means of a grinding disk of grain size F 200), honed finished surfaces (obtained for example by means of a polishing disk with grain size F 400), highly polished surfaces (obtained for example by means
37、of a polishing disk or felt), structured aspect (obtained by catch of print or artistic creation). If other types of surface finishes are used, these shall be declared by the manufacturer. For finely ground surfaces, honed surfaces and highly polished surfaces, it falls under the responsibility of t
38、he manufacturer to declare, according to the colour of the product, the minimum degree of gloss to be expected. 4.2.3 Requirements for the unexposed surface The unexposed surface shall have a regular appearance. Small cracks or cuts are permitted within 10 cm from the sides of the slabs. BS EN 15388
39、:2008EN 15388:2008 (E) 7 When the finishing process for the unexposed surface foresees a calibrated surface, the maximum surface roughness shall not exceed 0,5 mm. 5 Characteristics of agglomerated stones for vanity and kitchen tops 5.1 General The following characteristics shall be declared when su
40、bject to regulatory requirements and may be declared otherwise with reference to the conditions of the end usage. Contractual specifications may be used to establish reference values e.g. stated in design or supplier data sheet, due account taken of any regulatory requirements applicable. 5.2 Denomi
41、nation The denomination shall always be declared. The denomination is the indication of the commercial family of the product, commercial type, binders and type of aggregate, see EN 14618. 5.3 Visual appearance This characteristic shall always be declared. The colour, surface finish, etc. of the aggl
42、omerated stone shall be identified visually e.g. by a range of samples selected in agreement by supplier and purchaser. Any aesthetic visual variation is permissible provided that it is a declared aspect of the relevant type of agglomerated stone and provided that it does not adversely affect the pe
43、rformance of the slabs. 5.4 Reference sample, visual inspection and acceptance criteria A reference sample shall be an adequate number of pieces of agglomerated stone of sufficient size to indicate the general appearance of the finished work. The dimensions of individual pieces shall be at least 0,0
44、1 m2(typical values are between 0,01 and 0,25 m2in face area but may be more) and shall indicate the range of general appearance regarding the colouring, the physical structure and the surface finish. The reference sample does not imply strict uniformity between the sample itself and the actual supp
45、ly (e.g. variations in tonality may always occur due to natural raw materials). All the differences in aesthetical pattern between the slabs and the reference sample shall be considered typical of the agglomerated stone and not as flaws. Therefore they shall not become a reason for rejection, unless
46、 their presence exceeds 15 % of the surface and the typical pattern of the agglomerated stone is lost. Any comparison between production slab and reference sample shall be carried out by placing the reference sample in a vertical position against the production slab and viewing them at a distance of
47、 about two metres under normal daylight conditions and recording any visible differences in the characteristics of the agglomerated stone. NOTE The pieces should be analysed under similar conditions: for example, wet/dry, light, etc. According to this method, the difference in tonality and the gloss
48、 value (in the case of finely ground, honed or highly polished surfaces) measured at six different points of the slab shall be evaluated. BS EN 15388:2008EN 15388:2008 (E) 8 5.5 Reaction to fire This characteristic shall always be declared when the slabs are used in areas subjected to reaction to fi
49、re regulation and may be declared otherwise. Agglomerated stones (except those containing more than 1 % by mass or volume, whichever is the most onerous, of homogeneously distributed organic materials) are considered reaction to fire Class A1 following the Decision 96/603/EEC, as amended. For agglomerated stones containing more than 1 % by mass or volume, whichever is the most onerous, of homogeneously distributed organic materials, and having an end use subject to fire regulation, reaction to fire shall be
