27、e of a rough block size which is obtained by reducing each net dimension by 0,05 m (see Figure 1) BS EN 1467:2012EN 1467:2012 (E) 6 Dimensions in metres Key _._._._ gross size - commercial size Figure 1 Gross sizes, commercial sizes of a rough block 3.2 dimensions of a rough block length l, width b
28、and height h are the dimensions of a squared rough block. They are given in the stated sequence in meters to two decimals places 3.2.1 length l greater side in a natural layer where appropriate 3.2.2 width b smaller side in the natural layer or at right angles to length 3.2.3 height h side at right
29、angles to the natural layer (see Figure 2) or to the plane containing length l and width b BS EN 1467:2012EN 1467:2012 (E) 7 Key 1 natural layer Figure 2 Dimensions of a rough block 3.3 gross size of the rough block size defined by the lengths of the edges of the smallest parallelepiped circumscribe
30、d to a rough block (see Figure 1) 3.4 net size of a rough block size which is determined in the following manner: Establish the greatest inscribed parallelepiped block which shall not contain any sides without right angles nor contain drill holes and other holes. The resulting figure is the net size
31、 3.5 rough block basis of the usable stone consisting of rocks obtained directly from quarries or erratics with no processing whatsoever except extraction and shaping by cutting or splitting 3.6 rough block of specific size squared rough block with certain given dimensions 3.7 shapeless rough block
32、rough block without regular shape and size 3.8 squared rough block rough block which corresponds approximately to a regular parallelepiped Note 1 to entry: Normally the ratio obtainable by dividing the mass of the squared rough block by the apparent density should be bigger than 80 % of the gross si
33、ze. If such a ratio is equal to or less than 80 %, the block is considered a shapeless rough block. 4 Requirements 4.1 Requirements for geometric characteristics 4.1.1 Measurement criteria All measurements shall be carried out in accordance with EN 13373 and indicated in metres to two decimals place
34、s. BS EN 1467:2012EN 1467:2012 (E) 8 4.1.2 Requirements on shape The six sides of squared rough block shall be approximately flat, right-angled and parallel, and correspond to the shape of a parallelepiped. Local deviations from the parallelepiped shape are permitted. Shapeless rough blocks for comm
35、ercial purposes are only measured by mass, (see 4.1.4); gross size shall be provided upon request. Rough blocks of specific size shall have dimensions not lower than the minimum values and not greater than the maximum values agreed between the purchaser and supplier. 4.1.3 Requirements for volume Th
36、e volume of a rough block shall be stated in cubic metres to three decimals places. The volume may be calculated by dividing the mass of the block by the apparent density. 4.1.4 Requirements for mass The mass of a rough block shall be stated in tonnes with three decimals. The mass shall be obtained
37、by weighing; for squared blocks the approximate mass may be obtained by multiplying the volume by the apparent density. 4.2 Requirements of natural stone for rough blocks 4.2.1 General The following characteristics shall be declared where requested by this European Standard, or with reference to use
38、 conditions. The declared values shall be representative of the current production. However, due to natural variations of the stone materials, deviations from the declared values may occur. Expected deviations shall be indicated by the manufacturer. In case of layered stone: If a rough block contain
39、s different types of stones (see 4.2.2) all characteristics shall be declared. 4.2.2 Denomination The denomination (traditional name, petrological family, typical colour and place of origin) shall always be declared in accordance with EN 12440. NOTE The place of origin can be given by GPS coordinate
40、s. The petrologic definition shall be determined in accordance with EN 12407. 4.2.3 Visual appearance This characteristic shall be declared upon request. The colour, veining, texture, etc. of the stone shall be identified visually (for example by a polished reference sample). The reference sample sh
41、all be provided by the supplier. Any visual variations, for example inclusions and veins, are permissible, provided that they are characteristic of the relevant type of natural stone and provided that they do not adversely affect the performances of the stone products. BS EN 1467:2012EN 1467:2012 (E
42、) 9 4.2.4 Apparent density and open porosity This characteristic shall always be declared. The apparent density and open porosity shall be determined using the test method in EN 1936 and the mean value, lower expected value and standard deviation shall be declared. 4.2.5 Flexural strength This chara
43、cteristic shall always be declared. The flexural strength shall be determined using the test method in EN 12372 or EN 13161, and the mean value, lower expected value and standard deviation shall be declared. 4.2.6 Other requirements Where required, for example when the derived product is to be used
44、for a specific purpose, additional tests may be requested in accordance with relevant product standard (see EN 1469 1, EN 12057 2, EN 12058 3, etc.). 5 Marking As a minimum of identification, each consignment shall carry the following indications: the denomination of the natural stone, in accordance
45、 with EN 12440; the mass and the volume of each block; the dimensions (including at least gross and commercial sizes) of each block. The direction of the natural layer of each block shall be clearly marked where appropriate. Each block shall be clearly identified by a recorded identification system.
46、 6 Evaluation of conformity and factory production control 6.1 Evaluation of conformity The compliance with the requirements of this European Standard and with the stated values or classes of reaction to fire shall be demonstrated by carrying out initial type testing. Additionally, the manufacturer
47、shall exercise a permanent factory production control (FPC) and keep record of the results for at least 2 years. The declared values shall be representative of the current production, for example the lowest expected value or the minimum test value in normal production. For sampling see Annex A. When
48、 the rough blocks manufacturer declares conformity with some characteristics included in a product standard (see EN 1469 1, EN 12057 2, EN 12058 3, etc.), the evaluation of conformity of the block shall include initial type testing and factory production control as described in the appropriate produ
49、ct standard. BS EN 1467:2012EN 1467:2012 (E) 10 6.2 Initial type testing Initial type testing of a natural stone rough block, as given in Table 1, shall be carried out on the first application of this European Standard or at the beginning of production of a new type of stone; when significant variations occur in the material that are determined visually or by significant changes in FPC results.
