This European Standard shall be given the status of a national standard, either by public
15、ation of an identical text or by endorsement, at the latest by September 2002, and conflicting national standards shall be withdrawn at the latest by September 2002. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to impleme
16、nt this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 3 EN 13409:2002 (E) 1 Scope This European Standard specifies the measu
17、rement of setting time of a hydraulic setting smoothing and/or levelling compound which is referred to as ”smoothing and/or levelling compound”, after mixing. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative
18、 references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated referenc
19、es the latest edition of the publication referred to applies (including amendments). EN 196-3, Methods of testing cement - Part 3: Determination of setting time and soundness. EN 1937, Test method for hydraulic setting floor smoothing and/or levelling compounds - Standard mixing procedu- res. IS0 55
20、4, Standard atmospheres for conditioning and/or testing - Specifications. 3 Terms and definitions For the purposes of this European Standard, the following term and definition and those given in EN 1937 apply. 3.1 setting process of transition from plastic to solid state characterised by the initial
21、 and final penetration times 4 Principle The setting time is determined by observing the penetration of a needle into the smoothing and/or levelling compound mixture and recording the time for a given penetration value. 5 Safety Persons using this standard shall be familiar with normal laboratory pr
22、actice. This standard does not purport to address all the safety problems, if any, associated with its use. It is the responsibility of the user to establish safety and health practices and to ensure compliance with any European or national regulatory conditions. 6 Standard test conditions The stand
23、ard test conditions shall be (23 f 2) OC and (50 f 5) % relative humidity in accordance with IS0 554. All test materials and apparatus shall be stored under these conditions for the duration of the test. The tests shall be carried out in an area where the air circulation is less than 0,2 m/s. 4 EN 1
24、3409:2002 (E) 7 Apparatus and materials 7.1 diameter (1 ,I3 f 0,051) mm, and attachment made from corrosion resistant metal. Vicat apparatus, in accordance with EN 196-3 (see Figure 1) with a steel needle, length (50 f 1) mm, The total mass of the moving parts shall be (300 f 1) g. Their movement sh
25、all be truly vertical on an axis coincident with the steel needle and without significant friction. 7.2 Mould (see Figure la), containing the mixture under test shall be made of hard rubber. It shall be of truncated conical form (40,O f 0,2) mm deep and shall have internal diameters at top and botto
26、m of (70 f 5) mm and (80 f 5) mm respectively. The apparatus shall be sufficiently rigid and placed on a plane glass plate larger than the mould and at least 2,5 mm thick. Moulds of metal or plastics or of cylindrical form can be used provided they are of the specified depth and that they can be sho
27、wn to give the same test results as the specified hard rubber mould of truncated conical form. 7.3 Timer, accurate to 1 s. 7.4 Smoothing andlor levelling compound, in accordance with EN 1937. 8 Procedure 8.1 Calibration Calibrate the Vicat apparatus (7.1) with the needle (see Figure 1 b), attached i
28、n advance of the test by lowering the needle to rest on the base plate to be used. Adjust the pointer to zero. Raise the needle to the stand-by position. 8.2 Determination of initial setting time Lightly grease the glass plate and the mould. When the standard mixing procedure is completed in accorda
29、nce with EN 1937, fill the mould immediately without undue compaction or vibration and start the timer. Using a straight edge implement remove the excess with a gentle sawing action to leave a flat smooth surface. Place the test specimen centrally under the needle. When the smoothing and/or levellin
30、g compound mixture is showing signs of setting lower the needle gently until it is in contact with the surface. Pause in that position for between 1 s and 2 s in order to avoid initial velocity or forced acceleration of the moving parts. Then release quickly and allow the needle to penetrate vertica
31、lly into the smoothing and/or levelling compound. Read the scale when penetration has ceased or after 30 s after the release of the needle whichever is earlier. Record the scale reading which indicates the distance between the end of the needle and the base plate together with the time from zero. Re
32、move and clean the needle. Reposition the test specimen so that the next point of penetration is at a distance greater than 10 mm from the edge or of any previous test. Repeat at conveniently spaced time intervals, e. g. 5 min. until the scale reading is (4 f 1) mm. Time intervals near the end point
33、 should be reduced to ensure that successive test results do not vary excessively. Record to the nearest minute the time at which this occurs together with any abnormalities such as separation. 5 EN 13409:2002 (E) Dimensions in millimetres 12 Key 1 Hard rubber mould 2 Platorm for correcting weights

36、to when the reading is (4 f 1) mm on the scale, rounded to the nearest minute. Express the initial setting time as the elapsed time between the end of the mixing procedure to prepare the 9.2 mixture to when the needle first penetrates only 0,5 mm into the mixture, rounded to the nearest minute. Expr
37、ess the final setting time as the elapsed time between the end of the mixing procedure to prepare the 10 Test report The test report shall include: a) a reference to this European Standard; b) the designation of the smoothing and/or levelling compound under test, the date of manufacture and/or batch
38、 number, if known; c) the proportions of the liquid components by mass in relation to 100 parts of powder component; d) the method of mixing the compound and the total time in minutes in accordance with EN 1937; e) the initial and final setting times, in minutes; f) any deviations from the specified
39、 test methods; g) date of test. 7 BS EN 13409:2002 BSI 389 Chiswick High Road Lon don w4 4AL BSI is the independent national body responsible for preparing British Standards.
