This European Standard shall be given the status of a national standard, ei
15、ther by publication of an identical text or by endorsement, at the latest by September 2013, and conflicting national standards shall be withdrawn at the latest by September 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CE
16、N and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12088:1997. The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is one of a series o
17、f standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the approximation of l
18、aws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been drafted for applications in buildings but it may also be used in other areas where it
19、is relevant.

DIN EN 12088:2013-06 EN 12088:2013 (E) 5 1 Scope This European Standard specifies the equipment and procedures for determining the long-term water absorption of test spe
32、cimens by diffusion. It is applicable to thermal insulating products. It is intended to simulate the water absorption of products subjected to high relative humidities, approximating to 100 %, on both sides and subjected to a water vapour pressure gradient for a long period of time e.g. inverted roo
33、f or unprotected ground insulation. The test is not applicable for all types of thermal insulating products. The product standard should state for which of its products, if any, this test is applicable. NOTE For unprotected ground insulation, the temperature of 50 C might be replaced by a lower temp
34、erature, when more data is available. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the re

EN 12085, Thermal insulating products for building applications Determination of linear dimensions of test specimens 3 Terms and definitions This European Standard contains no terms and definitions. 4 Principle The long-term water absorption by d
36、iffusion is determined by measuring the increase in the mass of a test specimen subjected to a water vapour pressure difference and temperature gradient for a period of 28 days. 5 Apparatus 5.1 Balance, which allows the determination of the mass of a test specimen to 0,1 g. 5.2 Corrosion resistant c

The test speci
40、mens shall be squares with squarely cut edges having sides of (500 1) mm. If the product is not large enough to permit this size of test specimen, the test specimen size shall be reduced accordingly. Test specimens shall contain no joints. DIN EN 12088:2013-06 EN 12088:2013 (E) 7 6.2 Number of test
41、specimens The number of test specimens shall be at least two. 6.3 Preparation of test specimens The test specimens shall be cut so that they do not include original product edges. Test specimens shall be prepared by methods that do not substantially change the original structure of the product. Any
42、facings, skins and/or coatings shall be retained. Special methods of preparation, when needed, are given in the relevant product standard or any other European Technical Specification. 6.4 Conditioning of test specimens The test specimens shall be stored for at least 6 h at (23 5) C. In case of disp
43、ute, they shall be stored at (23 2) C and (50 5) % relative humidity for the time stated in the relevant product standard with a minimum of 6 h. 7 Procedure - Test procedure The dimensions of the test specimens shall be measured in accordance with EN 12085. Weigh the test specimen to the nearest 0,1
44、 g to determine its initial mass, m0. Place the test specimen on the frame of the container. If the product is faced on one side, begin the test with the facing upwards. Seal the bottom edge of the test specimen to the container. The width of the sealing shall be 10 mm (see Figure 1). Place the insu
45、lated cooling plate on the top of the test specimen. Subject the test specimen to a temperature and a water vapour pressure difference for 28 days by maintaining the water at a temperature of (50 1) C and the cooling on the other side at a temperature of (1 0,5) C. Turn the test specimen over every
46、7 days. After 28 days remove the test specimen and wipe off any surface water. Weigh the test specimen again to determine its mass, mD. 8 Calculation and expression of results The test result, Wdpor WdV, shall be the mean value of the individual values. Results shall not be extrapolated to other thi
47、cknesses. Calculate the long term water absorption by diffusion for each test specimen, Wdpor WdV, in kilograms per square metre or volume percent using Formula (1) or (2): Wdp= Am- mp0D(1) WdV= Wp0D100x d x Am- m(2) where m0is the initial mass of the test specimen, in kilograms; DIN EN 12088:2013-0
