    8、 All rights reservedForeword 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

    9、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

    10、(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 comm

    11、ittees 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 not

    12、be held responsible for identifying any or all such patent rights. ISO 15821 was prepared by Technical Committee ISO/TC 162, Doors and windows.

However, a leakage between the attaching rig and the pressure chamber is permitted unless it prevents the observation. 7.2 Procedure 7.2.1 General The test shall be carried out in accordance with 7.2.2 through 7.2.6. 7.2.2 Opening and clo

    33、sing actuation Prior to the test, open and close the opening parts, if any, of the test specimen five times and secure in closed position. 7.2.3 Preparatory pressure Apply static pressure for 1 min to the internal face of the test specimen, at the upper limit value of the test. 7.2.4 Water spraying

    34、Spray water across the weather-exposed face of the test specimen. The amount of water shall not be less than 3 l m 2 min 1to 4 l m 2 min 1 .

    40、 (informative) Common example of test-pressurization phases A.1 General This annex is for reference only and does not form a normative part of this International Standard. This annex applies to the case of not stipulating a median value, P, (3.4) in 7.2.5 and specifies the sequential pressurization

    41、phases. A.2 Pressurization phases The median value, P, is increased in increments and the test is carried out in sequential phases in the order shown in Figure A.1. The water-tightness shall be assessed at the median value maintained before water penetration. The sequence of median values, P, for th

    42、e phases is as follows: 100 Pa, 150 Pa, 250 Pa, 350 Pa, 500 Pa, 750 Pa, thereafter in steps of 250 Pa Opening and closing actuation: shall be conducted at the first test phase, but can be skipped at the next levels; see 7.2.2. Preparatory pressure shall be evaluated at every phase as a safety precau

    43、tion to ascertain whether the test specimen can withstand the level; see 7.2.3. Water spraying shall be carried out during each phase but stopped at the end of the phase. No water shall be sprayed in the interval between the test phases; see 7.2.4. ISO 15821:2007(E) ISO 2007 All rights reserved 9Key
