22、Aithgs reservde iii 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 a s
23、ubject 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 Commission
24、(IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inte
25、rnational 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent righ

The U-profiles shall be first cleaned and dried. Place a strip of PE-sheet (5.2) along the backside base of each U-profile, overlapping
36、 at the top and fixed at the outer reverse side, for example with adhesive tape. The PE-strip shall exactly cover the inside base of the U-profile. NOTE If the PE-strip is too narrow, the sealant will adhere to the backside base of the U-profile. If the PE-strip is too wide, it will curl inwards dec

39、 test specimen shall be used. The test specimens shall be tested either according to procedure A (see 6.2.2) or procedure B (see 6.2.3), as agreed. In the case of the sealant sliding from the U-profile, the inner surface of the U-profile shall be treated in accordance with the sealant manufacturers
40、recommendations. The test shall be repeated. 6.2.2 Procedure A Immediately after the preparation (6.1), place the test specimen in the oven (5.3 or 5.4) or in the refrigerated container (5.5) in a vertical position with the possible extension of the U-profile at the bottom (see Figure 1). Submit eac
