6、 . 8 ISO 16535:2012(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in
7、a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commissi
8、on (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules 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 c
9、ommittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 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 n
10、ot be held responsible for identifying any or all such patent rights. ISO 16535 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 1, Test and measurement methods. ISO 16535 includes the original EN 12087 prepared by Technical
11、 Committee CEN/TC 88 “Thermal insulating materials and products”, with the following clauses modified to reflect the conditions for tropical countries: Clause 5.4: Conditioning of test specimens; Clause 6.1: Test conditions; Clause 9: Test report. iv ISO 2012 All rights reserved ISO 16535:2012(E) In

29、mining the long-term water absorption of test specimens. It is applicable to thermal insulating products. This International Standard specifies two options: Method 1: partial immersion; and Method 2: total immersion. The long-term water absorption by partial immersion is intended to simulate the wat
30、er absorption caused by long-term water exposure. The long-term water absorption by total immersion is not directly related to the conditions on site, but has been recognized as a relevant condition of test for some products in some applications. 2 Normative references The following referenced docum

32、 linear dimensions of test specimens 3 Principle 3.1 Partial immersion (Method 1). The long-term water absorption by partial immersion is determined by measuring the change in mass of a test specimen, the lower part of which is in contact with water for a period of 28 days. The excess water adhering
33、 to the surface, not absorbed by the test specimen, is removed by drainage in Method 1A or taken into account by deduction of the initial water uptake in Method 1B. 3.2 Total immersion (Method 2). The long-term water absorption by total immersion is determined by measuring the change in mass of the
34、test specimen, totally immersed in water, over a period of 28 days. The excess water adhering to the surface, not absorbed by the test specimen, is removed by drainage in Method 2A or taken into account by deduction of the initial water uptake in Method 2B. 4 Apparatus 4.1 Balance, allows the determ
35、ination of the mass of a test specimen to 0,1 g. 4.2 Water tank, with a device for keeping the water level constant to within 2 mm, and a device to keep the test specimen in the required position. Examples of test devices are given in Figures 1, 2 and 3. The device to keep the test specimen in posit
36、ion shall not cover more than 15 % of the cross-sectional area of the test specimen, which is exposed to water. The device shall be such that the original form of the test specimen is maintained.

41、l be the original product thickness. The test specimens shall be squares with squarely cut edges having sides of (200 1) mm. 5.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard or any other European technical specification. In the absence
42、of such a specification, at least four test specimens shall be used. NOTE In the absence of a product standard or any other technical specification, the number of test specimens can be agreed between parties. 5.3 Preparation of test specimens The test specimens shall be cut so that they do not inclu
43、de original product edges. Test specimens shall be prepared by methods that do not substantially change the original structure of the product. Any skins, facings and/or coatings shall be retained. NOTE Special methods of preparation, when needed, are given in the relevant product standard or any oth
44、er European technical specification. 5.4 Conditioning 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
45、 In tropical countries, different conditioning and testing conditions are relevant. In this case, the conditions shall be (27 5) C and (65 5) % RH, and be stated clearly in the test report. 4 ISO 2012 All rights reserved ISO 16535:2012(E) 6 Procedure 6.1 Test conditions The test shall be carried ou

In this case, the conditions shall be (27 2) C and (65 5) % RH. 6.2 Test procedure The method shall be as specified in the relevant product sta
47、ndard or any other European technical specification. NOTE 1 In the absence of such a specification the method can be agreed between parties. The long-term water absorption is determined after 28 days immersion. NOTE 2 If requested, readings can be made at shorter time periods, e.g. after 7 day and 1
48、4 day immersion periods. The dimensions of the test specimens shall be measured in accordance with ISO 29768 to the nearest 0,5 mm before the test. If any dimensional changes are noticed after the immersion period, the dimensions of the test specimens should be measured again. 6.2.1 Long-term water
49、absorption by partial immersion (Method 1) 6.2.1.1 Method 1A (drainage) Weigh the test specimen to the nearest 0,1 g to determine its initial mass, m 0 . The test is made with half of the test specimens with one major face upwards. The other half are tested with the same major face downwards. Place the test specimen in the empty water tank and apply a sufficient load to keep it partially immersed when water is added. Carefull
