This European Standard shall be given the status of a national standard, either by publication of an identical text or b

16、y endorsement, at the latest by May 2000, and conflicting national standards shall be withdrawn at the latest by May 2000. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium

17、, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. OBSI 02-2000 STD-BSI BS EN L270b-ENGL 2000 H Lb24bb9 0830232 3TT Page 4 EN 12706:1999 1 Scope This European Standard spe

18、cifies a test method to assess the flow characteristics of a hydraulic setting floor smoothing and/or levelling compounds. Hydraulic setting floor smoothing and/or levelling compounds are referred to as “smoothing and/or levelling compound“ when mixed with water and/or mixing liquid according to the

19、 manufacturers instructions. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subse

20、quent 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 references the latest edition of the publication referred to applies: prEN 1937:1999, Test method for hydraulic setting floor smoothing and

21、/or levelling compounds - Standard mixing procedures IS0 554, Standard atmospheres for conditioning and/or testing - Specifications. 3 Terms and definitions For the purposes of this standard the following definition, together with those given in prEN 1937:1999, apply: 3.1 flow ability of the mixed f

22、loor smoothing and/or levelling compound to spread under its own weight 4 Principle This test method measures the flow properties of a known volume of floor smoothing and/or levelling compound mixture by releasing it from a rigid tube after a given time. The diameter of the spread mixture is measure

23、d after a specified time. 5 Safety Persons using this standard shall be familiar with normal laboratory practice. This standard does not purport to address all safety problems, if any, associated with its use. It is the responsibility of the user to establish safety and health practices and to ensur

24、e compliance with any European and national regulatory conditions. 6 Apparatus and material 6.1 Tubes, made of smooth, non-corrosive metal, of internal diameter (30 * 0,l) mm and height (50 * 0,l) mm. 6.2 Glass plate, clean and dry, dimensions: 300 mm x 300 mm x 6 mm, for example.

26、 shall be conditioned at (23 f 2) eC and (50 f 5) % relative humidity in accordance with IS0 554. 8 Procedure Place one tube (6.1) centrally on a glass plate (6.2) and set it on a firm horizontal base. When the standard mixing procedure is completed in accordance with prEN 1937:1999, fill the tube t

27、o the top edge with the smoothing and/or levelling compound mixture (6.5). Immediately the tube is filled, start the timer (6.3) and simultaneously lift the tube from the glass plate in a vertical direction to a height of 50 mm to 100 mm within 2 s and allow to drain for 10 s to 15 s. After not less

28、 than 4 min measure the diameter of the flowed mixture in two directions at right angles, using the linear measuring equipment (6.4). Record the results as a measure of the initial flow. If more information is required, fill additional tubes with the same mixture, without further mixing, at interval

29、s of 5 minutes from the start of the timer. Lift and measure according to the procedure for the first tube. Record the results as a measure of flow versus time. 9 Evaluation and expression of results Record the flow of the mixture as the mean value of the two measurements of diameter to the nearest

30、1 mm, in each test. 10 Test report The test report shall include: a) a reference to this European Standard; b) identification of the smoothing and/or levelling compound stating the date of manufacture and/or batch number, if known; c) the mixing procedure used in accordance with prEN 1937:1999 and a

31、mount of water and/or mixing liquid used as percentage of the powder by weight; d) the initial flow and the flow versus time in millimetres; e) a graphical illustration of flow versus time; f) any physical changes or abnormalities observed during the test: g) any factors which may have affected the

32、result; h) date of test.
