6、al standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internatio

7、nal organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rule

8、s given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at l

9、east 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16536 was prepared by Technical Committee ISO/TC 1

28、products for building applications Determination of long-term water absorption by diffusion 1 Scope This International Standard specifies the equipment and procedures for determining the long-term water absorption of test specimens by diffusion. It is applicable to thermal insulating products. The t

29、est 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 roof or unprotected ground insulation. The test is not applicable for a

30、ll 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 may be replaced by a lower temperature, when more data are available. 2 Normative references The foll

36、ecimens The thickness of the test specimens shall be the original product thickness. The test specimens 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. T

37、est specimens shall contain no joints. 5.2 Number of test specimens The number of test specimens shall be at least two. 2 ISO 2012 All rights reserved ISO 16536:2012(E) 5.3 Preparation of test specimens The test specimens shall be cut so that they do not include original product edges. Test specimen

38、s shall be prepared by methods that do not substantially change the original structure of the product. Any facings, skins and/or coatings shall be retained. NOTE Special methods of preparation, when needed, are given in the relevant product standard or any other technical specification. 5.4 Conditio

39、ning of test specimens The test specimens shall be stored for at least 6 h at (23 5) C. In case of dispute they shall be stored at (23 2) C and (50 5) % relative humidity (RH) for the time stated in the relevant product standard with a minimum of 6 h. In tropical countries, different conditioning an

40、d testing conditions can be relevant. In this case, the conditions shall be (27 5) C and (65 5) % RH, and be stated clearly in the test report. 6 Procedure 6.1 Test procedure The dimensions of the test specimens shall be measured in accordance with ISO 29768. Weigh the test specimen to the nearest 0

41、1 g to determine its initial mass, m 0 . Place the test specimen on the frame of the container. If the product is faced on one side, begin the test with it 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 i

42、nsulated cooling plate on 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 7

43、 days. After 28 days, remove the test specimen and wipe off any surface water. Weigh the test specimen again to determine its mass, m D . 6.2 Test conditions The test shall be carried out at (23 2) C and (50 5) % RH. NOTE Other conditions may be given in the relevant product standard or can be agree

44、d between parties. In tropical countries, different conditioning and testing conditions can be relevant. In this case, the conditions shall be (27 2) C and (65 5) % RH. 7 Calculation and expression of results The test result, W dpor W dV , shall be the mean value of the individual values. Results sh

45、all not be extrapolated to other thicknesses.
