The work of preparing International Standards is nor
7、mally 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in
8、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 rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepar
9、e 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 least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that som
10、e 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 16545 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 1, Test and
11、measurement methods. ISO 16545 includes the original EN 13793 prepared by Technical Committee CEN/TC 88 “Thermal insulating materials and products”, with the following clauses modified to reflect the conditions for tropical countries: Clause 6.4: Conditioning of test specimens; Clause 7.1: Test cond

37、onal) to be tested. One of the plates shall be fixed and the other movable with a centrally positioned ball joint, if appropriate, to ensure that only axial force is applied to the test specimen. The movable plate shall be capable of following a sinusoidal waveform displacement in accordance with th
38、e conditions described in Clause 7 and illustrated in Figure 1. The load cycle should be considered as a sinusoidal waveform if the deviation of the actual curve compared to the theoretical sine curve at every point following the time axis does not exceed 5 % of the duration of one cycle.

40、 or of the distance between the two plates and which permits reading to 5 % or 0,1 mm, whichever is the smaller (see 5.3). 5.3 Measurement of force Sensor 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
41、 that its own deformation during the course of the measuring operation is negligible compared with that being measured. If it is not sensor deformation shall be taken into account by calculation. The sensor shall allow the continuous measurement of the force permitting reading to 3 %. 5.4 Recording
42、device Device for the simultaneous recording of the force, F, and the displacement, X, which provides a curve of F as a function of X. NOTE It is most likely that only those machines which incorporate a high precision aligned loading frame with a servo-hydraulic system control and a computer control
43、led actuator will comply with the required level of accuracy. The measuring devices for displacement and force are likely to comprise electronic transducers and sensors. In order to achieve the maximum level of accuracy, it is desirable that all test controlling, data generation and data management
44、(including all output of tables and plots) are concentrated in one computer system. 6 Test specimens 6.1 Dimensions of test specimens The test specimens shall be at the original product thickness. The width of the test specimens shall not be less than the thickness. Products with integrally moulded
45、skins which are retained in use shall be tested with these skins intact. Test specimens shall not be layered to produce a greater thickness for testing. Test specimens shall be squarely cut and square with recommended cross-section areas as follows: 50 mm 50 mm; or 100 mm 100 mm; or 150 mm 150 mm; o
46、r 200 mm 200 mm; or 300 mm 300 mm. The choice of dimensions to be used shall be as specified in the relevant product standard. In the absence of a product standard or any other European technical specification, the dimensions of test specimens may be agreed between parties. The linear dimensions sha
47、ll be determined in accordance with ISO 29768 with a limit deviation of 0,5 %. The tolerance on parallelism and flatness between the two faces of the test specimen shall not be greater than 0,5 % of the specimen side with a maximum of 0,5 mm. If the test specimens are not flat, they shall be ground
48、flat or an appropriate levelling layer shall be applied to prepare the surface for the test. No significant deformation shall occur in the levelling layer during the test. ISO 2012 All rights reserved 3 ISO 16545:2012(E) In case that a gypsum levelling layer is used, the determination of the dimensi
49、ons shall occur prior to the application of the layers. NOTE The accuracy of the test result is reduced if the test specimens have a thickness of less than 20 mm. 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. In the absence of such a specification, five test specimens shall be used for each stress selected. NOTE In the absence of a product standard or any
