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 O
13、ctober 2013, and conflicting national standards shall be withdrawn at the latest by October 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such pat

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard is one of a

BS EN 14617-1:2013EN 14617-1:2013 (E) 4 1 Scope This European Standard specifies a method for determining the apparent density and water absorption of agglomerated sto
20、ne products. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 apparent density Mvratio between mass (expressed in kg) and apparent volume (expressed in m3) situated within the external surface of the body 2.2 water absorption C maximum amount
21、of water absorbed by the material when soaked in deionised water at room temperature and pressure according to the procedure described below, expressed as a percentage of the dry mass of the sample 3 Apparatus 3.1 A covered tank with a flat base comprising small non-oxidising and non-absorbent suppo
22、rts for the specimens. 3.2 A device able to maintain a constant water level in the tank, described in 4.1. 3.3 A time counter with an accuracy of one second. 3.4 A weighing instrument with an accuracy of 0,01 % of the sample mass. 3.5 A hydrostatic balance accurate to at least 0,01 % of the sample m
23、ass. 3.6 A ventilated oven capable of maintaining a temperature of (70 5) C. 4 Preparation of the specimens 4.1 Sampling The sampling is not the responsibility of the test laboratory except where especially requested. At least six specimens selected from a homogeneous batch consisting of the same ma
24、terial mixture should be tested. The final finishing of the specimen should be the same as the end product (sand blasted, gauged or polished surface) but without chemical surface treatment. The dimensions of the sample are (100 x 100) mm length and width and (10 2) mm thickness. 4.2 Specimen conditi
25、oning The specimens should be dried in a stove at (70 5) C until the difference between two successive weighings at (24 2) h intervals is less than 0,1 % of the sample mass. The specimens shall be kept in a desiccator until room temperature (20 5) C is attained. BS EN 14617-1:2013EN 14617-1:2013 (E)
26、 5 5 Test procedure After drying and weighing (Mo), place the specimens in a tank on two supports in order to reduce the support contact surface to a minimum. Slowly pour the deionised water into a container until the specimens are completely immersed and covered by 2 cm of water. After (1 0,25) h,
27、(8 0,5) h and (24 1) h from the beginning of the tests, and later at regular intervals of (24 1) h, take the specimens out of the water, wipe with a damp cloth and weigh them in air. Continue to immerse the specimens in water and repeat the tests until the weight variation specimens (Mt) in three su
28、ccessive weighings is less than 0,1 %. Immediately after the final weighing of each sample, determine the apparent mass (Ma) by weighing the sample in water using a hydrostatic balance. 6 Expression of results 6.1 The apparent density Mv, in kg/ m3is given by: 2o HOta()vMMMM=(1) where Mois sample ma
29、ss weighed in air after drying, in kilograms; Mtis sample mass soaked in water (6), wiped by a damp cloth and weighed in air, in kilograms; Mais sample mass soaked in water and weighed in water, in kilograms; H2O is the true density of water at the measuring temperature, in kilograms/ cubic metre. 6
30、.2 Water absorption C in percentage (%) is given by: oot)(MMMC=100(2) 6.3 For a more complete documentation of water absorption of a material, the amount of water absorbed relative to 1 h, 8 h, 24 h, 48 h, 72 h, etc. can be calculated. The amount of water absorbed (Ciin percent) at the generic time
31、tiis given by: ooii)(MMMC=100(3) where Miis sample mass weighed in air after titime of water absorption. Porosities (open and total) may be calculated according to EN 1936. 7 Test report The test report shall contain the following information: a) unique identification number of the report; BS EN 146

33、of the client to supply the following information: 1) name of the supplier; 2) name of the person or organisation which carried out the sampling; 3) surface finish of the specimens (if relevant to the test); 4) nature of the binders; f) date of delivery of the sample or of the specimens; g) date whe
34、n the test specimens were prepared (if relevant) and the date of testing; h) number of specimens in the sample; i) dimensions of the specimens; j) apparent density values of each specimen and the average value; k) water absorption value of each specimen and the average value; l) all deviations from
35、the standard and their justification; m) remarks. The test report shall contain the signature(s) and role(s) of the responsible(s) for the testing and the written consent of the test laboratory. It shall also state that the report shall not be partially reproduced without the written consent of the
