8、wide 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 a subject for which a technical committee has been established has the right to be represented on t

9、hat committee. International 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

10、 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 committees are circulated to the member bodies for voting. Publication as an International Standard

11、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 not be held responsible for identifying any or all such patent rights. ISO 16544 was prepared by Tec

30、reserved INTERNATIONAL STANDARD ISO 16544:2012(E) Thermal insulating products for building applications Conditioning to moisture equilibrium under specified temperature and humidity conditions 1 Scope This International Standard specifies equipment and procedures to condition a thermal insulating pr

31、oduct to equilibrium moisture content at (23 2) C and (50 5) % relative humidity. It is also applicable to thermal insulating products with moulded skins but is not normally relevant for faced products or for products with other surface treatments. NOTE 1 The normally specified moisture content is t

32、he result of the equilibrium between the atmosphere and the product at (23 2) C and (50 5) % relative humidity. This International Standard can also be used if a product has to be conditioned to other relative humidities. NOTE 2 The moisture equilibrium may, due to hysteresis effects, differ dependi

33、ng on whether the equilibrium has been reached by absorption or by desorption. In addition, perfect equilibrium can require a very long time to be reached. Therefore, it is necessary to accept equilibrium within a certain accuracy. NOTE 3 For products that do not absorb moisture, conditioning is not

34、 needed. It should, nevertheless, be ensured that there is no water on the surface before testing. 2 Normative references The following referenced documents are indispensable for the application of this document.

39、ions EPS expanded polystyrene ICB insulation cork board MW mineral wool PUR polyurethane foam XPS extruded polystyrene foam 4 Principle The conditioning is carried out using one or two steps (see Figure 1). Step 1 is conditioning the test specimen to a moisture content within the hygroscopic range.

40、This conditioning may take place in an atmosphere 23/50 or in a ventilated oven. The choice of condition depends on the type of material. Alternative I shows drying in atmosphere 23/50 and alternative II drying in a heated oven. Step 2 is conditioning the test specimen to equilibrium with an atmosph

The test specimens shall be squarely cut and square having sides of (200 1) mm. 6.2 Number of test specimens The number of test s

45、pecimens shall be as specified in the relevant product standard. If the number is not specified, then at least three test specimens shall be conditioned.

Any surface skins, facings and/or coatings shall be retained. 6.4 Preconditioning of test specimens If the procedure shown i

47、n Figure 1a) is used, ensure that the test specimens have a moisture content well above the hygroscopic range. If, in this case, the hygroscopic sorption curve for the product is not known, it shall be determined in accordance with ISO 12571. NOTE To increase the moisture content to above the hygros

48、copic range, it may be necessary to immerse the test specimens in water, expose them to the exterior climate or expose them to water vapour in accordance with ISO 16536. 6.5 Conditioning of test specimen in tropical countries In tropical countries, different conditioning and testing conditions can b

In this case, the moisture content shall be in equilibrium with atmosphere (27 5) C and (65 5) % RH, and this shall be stated clearly in the test report. 7 Procedure 7.1 General Determine the linear dimensions in accordance with ISO 29768 with an accuracy of 1 %.
