The work of preparing International Standards is normally carried out throug
9、h 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborat
10、es closely with the International Electrotechnical Commission (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 Standard
11、s. 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 least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of thi

25、 and procedures for determining the thickness of thermal insulating products for impact sound insulation in floating floor applications. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited appl
26、ies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 29768, Thermal insulating products for building applications Determination of linear dimensions of test specimens 3 Terms and definitions For the purposes of this document, the followin
27、g terms and definitions apply. 3.1 thickness d Lthickness of the product under a load of 250 Pa 3.2 thickness d Fthickness of the product under a load of 2 kPa 3.3 thickness d Bthickness of the product under a load of 2 kPa after application of a short-term, additional load of 48 kPa 4 Principle The
28、 thickness is determined as the distance measured between a rigid, flat base plate on which the test specimen rests and a rigid, flat pressure plate exerting different specified pressures on the top surface of the test specimen. ISO 29770:2008(E) 2 ISO 2008 All rights reserved5 Apparatus 5.1 Dial ga
29、uge, permitting readings to 0,1 mm, mounted on a rigid frame fastened to a rigid, flat base plate. A device with the same accuracy for two readings of the thickness/deformation is placed symmetrically on a diagonal on the upper square plate of the device. The mean of these two readings is the thickn
30、ess/deformation. 5.2 Base plate and pressure plate, at least as large as the test specimen. 5.3 Pressure device, capable of exerting a total pressure on the test specimen of (250 5) Pa, including the force exerted by the dial gauge. 5.4 Pressure device, capable of exerting a total pressure on the te
31、st specimen of (2 000 20) Pa, including the force exerted by the dial gauge. 5.5 Pressure device, capable of exerting a total pressure on the test specimen of (50 000 500) Pa. As an alternative to 5.1 through 5.5, a compression-testing machine suited to the range of force and displacement involved c
32、an be used. The compression-testing machine shall have two very rigid, polished, square, plane parallel plates, the length of one side of which is at least as large as the test specimen side being tested. One of the plates shall be fixed and the other movable, if appropriate, with a centrally positi
33、oned knee ball joint to ensure that only an axial force is applied to the test specimen. A device for measuring the displacement shall be fitted to the compression-testing machine that allows measurement of the displacement of the movable plate and that permits a reading to 0,1 mm. A sensor shall be
34、 fitted to one of the machine plates to measure the force produced by the reaction of the test specimen upon the plates. This sensor shall be such that either its own deformation during the course of the measuring operation is negligible compared with that being measured or its deformation shall be
35、taken into account by calculation. In addition, it shall allow continuous measurement of the force permitting a reading to 1 %. When measurements are made on a movable plate and not in the axis, two sensors, placed symmetrically with respect to the axis, shall be used and then the mean value of the
36、two measurements is used. 6 Test specimens 6.1 Dimensions of test specimens The thickness of the test specimens shall be the original product thickness. The test specimens shall be squarely cut and square having sides of (200 1) mm. The length and width shall be determined in accordance with ISO 297
37、68, with an accuracy of 1 mm. 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. If the number is not specified, then ten test specimens shall be used. In the absence of a product standard or any other international or European technical
38、 specification, the number of test specimens may be agreed between parties. ISO 29770:2008(E) ISO 2008 All rights reserved 3 6.3 Preparation of the test specimens The test specimens shall be cut so that they do not include product edges. The test specimens shall be prepared by methods that do not ch
39、ange the original structure of the product. Any skins, facings and/or coatings shall be retained. 6.4 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 for the time specif
40、ied in the relevant product standard. In tropical countries, different conditioning and testing conditions can be relevant. In this case, the conditions shall be 27 C and 65 % RH and be stated clearly in the test report. 7 Procedure 7.1 Test conditions The test shall be carried out at (23 5) C. In c
41、ase of dispute, it shall be carried out at (23 2) C and (50 5) % relative humidity. In tropical countries, different conditioning and testing conditions can be relevant. In this case, the conditions shall be 27 C and 65 % RH and be stated clearly in the test report. 7.2 Test procedure 7.2.1 General
42、The procedure for determining the thickness of the test specimen is shown in Figure 1.

43、specimen on the rigid, flat, horizontal base plate, ensuring that the measuring area is in contact with the base plate. Place the test specimens, if faced or coated on one side, with the facing or coating against the base plate. Load the test specimen with a device exerting a pressure of 250 Pa. Mea
44、sure the thickness, to the nearest 0,1 mm, (120 5) s after placing the pressure plate in position. The thickness may be measured with the dial gauge at two diagonally opposite measuring devices (pins) forced through an opening in the centre of the pressure plate. 7.2.3 Thicknesses d Fand d BThe thic
45、knesses d Fand d Bshall be determined on the same test specimen that was previously used for determining the thickness d L . Load the test specimens with a device exerting a pressure of 2 kPa. Measure the thickness d F , to the nearest 0,1 mm, (120 5) s after applying this pressure. Apply an additio
46、nal pressure of 48 kPa. Remove this additional pressure after (120 5) s. Measure the thickness, d B , to the nearest 0,1 mm, (120 5) s or (300 10) s after removing the pressure of 48 kPa. The pause before measuring the thickness, either 120 s or 300 s, shall be as specified in the relevant product s
47、tandard. In the absence of a product standard or any other international or European technical specification, the pause time may be agreed upon between parties. 8 Calculation and expression of results The results for each thickness d L , d Fand d Bshall be the mean value of the respective measuremen
48、ts made on all test specimens, rounded to the nearest 0,1 mm. 9 Accuracy of measurement NOTE It has not been possible to include a statement on the accuracy of the measurements in this edition of this International Standard, but it is intended to include such a statement when this International Stan
