30、e within hygroscopic capillary building materials is a combination of vapour and liquid flows which have complex interactions with the temperature and humidity gradients and the properties of the materials present. Three stages can be identified. a) At very low humidities transport is by vapour diff

31、usion alone and the permeability can be derived from dry-cup tests, defined in ISO 12572. b) At higher relative humidities in the hygroscopic region, up to about 95 % relative humidity, there is a mixture of gas and water filled pores with simultaneous flows of vapour and liquid. The increasing liqu

32、id flow causes the exponentially increasing permeability measured by cup tests under isothermal conditions. However, under practical, non-isothermal conditions this liquid flow could increase, or decrease, the total mass flow. c) Above about 95 % relative humidity, depending on the material, the tot

33、al mass transport is governed by transport in the liquid phase. This is the situation that arises when a material is dipped in water or severely wetted e.g. by driving rain. The water moves under the hydraulic pressure, the negative suction pressure. After the water source is removed, the hydraulic

34、pressure ceases and the liquid is redistributed within the material at a different rate (stages b) and c) do not necessarily apply to all hygroscopic materials). Methods are currently being developed in research laboratories to quantify capillary transport and measure the relevant coefficients. At p

35、resent, however, these involve sophisticated measuring techniques such as gamma ray and neutron absorption or Nuclear Magnetic Resonance (NMR) spectroscopy together with complex mathematical methods to analyse the results: comparisons between laboratories have shown that further work is needed to de

36、velop standard techniques. It will, therefore, be a number of years before it is possible to standardise such methods see annex A for further information. At present it is possible to standardise the measurement of the absorption of liquid water into the surface of a material, which gives an indicat

37、or of its liquid transport performance. DIN EN ISO 15148:2016-12 EN ISO 15148:2002 + A1:2016 (E) 6 1 Scope This European Standard specifies a method for determining, by partial immersion with no temperature gradient, the short-term liquid water absorption coefficient. It is intended to assess the ra

38、te of absorption of water, by capillary action from continuous or driving rain during on site storage or construction, by insulating and other materials, which are normally protected. The method is suitable for renders or coatings tested in conjunction with the substrate on which they are normally m

39、ounted. It is not intended to assess the absorption of water by materials used under water or in overall contact with saturated ground, where a total immersion test is more appropriate. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other pu

40、blications. These normative 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 rev

41、ision. For undated references the latest edition of the publication referred to applies (including amendments).

The alternative definition in

45、terms of hours is widely used. 4 Principle The water absorption by partial immersion is determined by measuring the change in mass of the test specimen, the bottom surface of which is in contact with water, over a period which is usually at least 24 h. The water adhering to the surface and not absor

46、bed by the product is completely removed by, for example, blotting with a sponge before the specimen is weighed. 5 Apparatus The test apparatus shall include: a) balance, capable of weighing a test specimen to an accuracy of 0,1 % of the mass of the specimen; b) water tank with a device for keeping

47、the water level constant to 2 mm and a device to keep the test specimen in position. The tank shall include point supports, which do not damage the specimen, to keep the specimen at least 5 mm clear of the base; c) timer accurate to at least one second in 24 h. 6 Test specimens 6.1 Shape of test spe

48、cimens Test specimens shall be representative of the material or product and of regular shape with constant cross section to ensure one dimensional water flow. The faces shall be free from surface irregularities. DIN EN ISO 15148:2016-12 EN ISO 15148:2002 + A1:2016 (E) 8 6.2 Dimensions of test speci

However, in the case of materials including macroscopic particles such as aggregates, the side of a square specimen or the smallest diameter of the face shall be at least ten times the largest particle size. NOTE Larger specimens, preferably with a face area of at least 100 cm2, are advised as they will lead to greater accuracy. 6.2.2 Thickness Where possible, the specime
