3、2009-10 National foreword This standard has been prepared by Technical Committee CEN/TC 246 “Natural stones” (Secretariat: UNI, Italy). At present a DIN committee does not exist for this standard since the parties concerned have not shown any interest in work on the subject. The Normenausschuss Mate
4、rialprfung (Materials Testing Standards Committee) is obliged to publish the standard, however, as the subject falls in its domain. Amendments This standard differs from DIN EN 14618:2005-06 as follows: a) The definitions of some terms have been modified. b) The terms “grit” (4.1.7), “shelf life” (5
5、.21) and “rough slab” (6.6) have been deleted. c) The terms “agglomerated stone product” (3.2), “moulding under vacuum” (5.17), “open cast moulding” (5.18), “polished finish” (5.19), “cut to size slab” (6.4) and “textured upper face slab” (6.9) have been added.

Agglomerated stone products are industrial products mainly made of hydraulic cement, resin or mi
17、xture of both, stones and other additions. They are industrially manufactured in geometrical shapes at fixed plants by moulding techniques. They are put on the market in the form of rough blocks, rough slabs, slabs, tiles, dimensional stone works, and any other cut to size products. All other agglom
18、erated stones products not intended to be used for flooring, wall finishes and similar uses (like drainage channels, structural elements, etc.) are excluded from the field of this standard. This European Standard is not applicable to terrazzo tiles covered by EN 13748-1 1 and EN 13748-2 2. 2 Normati

20、ology 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 12670:2001 and the following apply. 3.1 agglomerated stone industrial product manufactured from a mixture of aggregates of various sizes and natures (generally coming from natural stones), sometime
21、s mixed with other compatible materials, additions and binder NOTE The binder could be resin, hydraulic cement or mixture of both (in various percentages). Aggregates consist of natural and/or recycled stones and/or different additions such as crushed ceramics, glass, mirrors. They are bound via res
22、in and filler or cement and water or mixture of both. The manufacturing process is irreversible. 3.2 agglomerated stone product semi-finished product manufactured from agglomerated stone in form of blocks or slabs, which can be transformed in finished slabs, tiles, vanity tops or similar elements. N
23、OTE Under the agglomerated stones term fall architectural elements, complementary to products for flooring and wall finishes, which can or cannot be subsequently cut to size. Products manufactured by the technology of the agglomerated stones could be impregnated by suitable chemicals in order to wat
24、erproof/seal open pores. The products can be also sealed with putty in order to fill in the surface defects accidentally present in some natural stones and other aggregates. 3.3 classification of agglomerated stones classification according to the type of the binder and the nature of the aggregates
25、of the agglomerated stone product NOTE If the volume of the binding material is greater than the volume of the aggregates, the resulting material cannot be classified as agglomerated stone. 4DIN EN 14618:2009-10 EN 14618:2009 (E) 3.3.1 classification according to the type of the binder classificatio
26、n according to the binder of the agglomerated stone product, i.e. resin, hydraulic cement or mixtures of resin and cement NOTE Agglomerated stone product can be bound by resin (e.g. thermosetting resin) or by other suitable organic or inorganic polymer which can be irreversibly hardened Agglomerated
27、 stone product can be bound by hydraulic cement (white or grey). Agglomerated stone product can be bound by mixtures of resin and cement. 3.3.2 classification according to the mineral nature of the aggregates classification according to the mineral nature of the agglomerated stone product, i.e. carb
28、onate nature, silica nature or carbonate and silica nature NOTE Agglomerated stone product can be constituted of aggregates of carbonate nature e.g. marble, limestone, etc. Agglomerated stone product can be constituted of aggregates of silica nature e.g. quartz, sandstone, granite, etc. Agglomerated
29、 stone product either of carbonate or of silica nature can contain aggregates such as crushed ceramics, glass, mirrors, etc. Agglomerated stone product can be constituted of aggregates of both carbonate and silica nature. 4 Terminology of agglomerated stones 4.1 Terms of fragmented aggregates 4.1.1
