28、for scientific examinations, but which are not relevant for the application in practice according to this European Standard. 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 commercial size of a rough block size
29、which is obtained by reducing each net dimension by 0,05 m (see Figure 1) DIN EN 1467:2012-06 EN 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 and height h are th
30、e 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 angles to the natur
31、al layer (see Figure 2) or to the plane containing length l and width b DIN EN 1467:2012-06 EN 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 circumscribed to a rough b
32、lock (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 3.5 rough blo
33、ck 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 rough block wi
34、thout 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 size. If such a
35、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 places. DIN EN 1467
36、:2012-06 EN 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 commercial pu
37、rposes 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 The volume
38、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 by weighi
39、ng; 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 conditio
40、ns. 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 contains differe
41、nt 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 coordinates. The pe
42、trologic 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 shall be pr
43、ovided 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. DIN EN 1467:2012-06 EN 1467:2012 (E) 9
44、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 character
45、istic 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 for
46、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 wit
47、h 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. 6 E
48、valuation 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 shall exercise a permanent factory production control (FPC) and keep record of the results for at least
