The work of preparing International Stan
10、dards 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 that committee. International organizations, governmental and non-governmental, in liaison with ISO, also t
11、ake part in 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
12、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 requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibil
13、ity 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 5925-1 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 2, Fire containment. This second edition cancels
14、 and replaces the first edition (ISO 5925-1:1981), which has been technically revised. ISO 5925 consists of the following parts, under the general title Fire tests Smoke-control door and shutter assemblies: Part 1: Ambient- and medium-temperature leakage tests Part 2: Commentary on test method and t
15、he applicability of test conditions and the use of test data in a smoke containment strategy ISO 5925-1:2007(E) ISO 2007 All rights reserved v Introduction This part of ISO 5925 has been prepared to provide a test method for determining the smoke leakage through door and shutter assemblies. It is pa
16、rt of the series of International Standards dealing with fire doors, e.g. ISO 3008. This second edition of ISO 5925-1 combines the procedure published in the first edition and the proposed revisions to it on medium-temperature testing. A further test procedure planned as Part 3 for high-temperature
17、testing is currently in abeyance. Additional requirements for the installation and use of smoke-control door and shutter assemblies can be found in other International Standards and national regulations. INTERNATIONAL STANDARD ISO 5925-1:2007(E) ISO 2007 All rights reserved 1 Fire tests Smoke-contro
18、l door and shutter assemblies Part 1: Ambient- and medium-temperature leakage tests 1 Scope The test described in this part of ISO 5925 determines the rate of leakage of ambient (cold) and medium (warm) temperature smoke from one side of door and shutter assemblies to the other under the specified t
19、est conditions. The test is applicable to door and shutter assemblies of different configurations intended for purposes of controlling the passage of smoke in case of fire. The acceptable leakage rates for different situations are not addressed in this part of ISO 5925, but rather are specified by t
20、he regulations of the controlling authorities. The principle of the test is explained briefly in Annex A. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, th
21、e latest edition of the referenced document (including any amendments) applies. ISO 834-1, Fire-resistance tests Elements of building construction Part 1: General requirements 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 door and shutter a

24、ure average air temperature of (20 10) C ISO 5925-1:2007(E) 2 ISO 2007 All rights reserved3.4 medium temperature average air temperature of (200 20) C 3.5 leakage rate rate of air flow, corrected to standard temperature and pressure conditions, measured under specified differential pressure across a
25、 closed door and shutter assembly NOTE Leakage rate is expressed in cubic metres per hour. 3.6 differential pressure difference in static pressure created during the test between the inside and outside of the test chamber, as measured across a closed door NOTE The symbol for pressure is p and it is
26、expressed in pascals (1 Pa = 1 N/m 2 ). 3.7 test specimen door and shutter assembly on which leakage measurements are to be made, including all components necessary for the use of the door when installed in a building, the seal between the frame and the wall and any associated construction which is
27、provided 3.8 associated construction specific form of construction into which the test specimen can be mounted NOTE If an associated construction is used in the test, it shall be identical to that in which the door and shutter assembly is designed to be installed in practice. The method of sealing t
28、he joint between the test specimen and the associated construction is specific to that construction and forms part of the construction being evaluated by the test. 3.9 supporting construction impermeable form of construction of adequate strength and stiffness to support the test specimen when an ass
29、ociated construction is not provided and to fill the opening in the test chamber when an associated construction is provided NOTE The seal between the test assembly and the supporting construction is intended to be impermeable and withstand the test temperature, but it is not considered as part of t
30、he test construction being evaluated. 4 Symbols and abbreviated terms See Figure 1. q aapparatus (test chamber) leakage rate, expressed in cubic metres per hour, corrected to standard reference conditions for temperature and pressure (see 10.2) q ttotal leakage rate, expressed in cubic metres per ho

33、us 5 Test apparatus The test apparatus consists essentially of a test chamber with an open front in which the test specimen (door sample) is mounted to provide a sealed enclosure. The opening shall be sufficient to accommodate the door sample with its associated and/or supporting construction. In ge
34、neral, an opening of 3 m 3 m is sufficient. A smaller apparatus is feasible if its use is restricted to normal single-leaf doors. An air supply system shall be provided to create a pressure differential across the door sample of at least 55 Pa. Provision shall be made to heat the circulating air to
35、the test temperature of (200 20) C and to control the temperature within the prescribed limits. Annex B provides a general specification for a suitable apparatus, but other designs can achieve the same objectives. The test apparatus leakage rate, q a , shall not exceed 7 m 3 /h at ambient or medium
36、temperature. The air supply and heating systems shall be able to replace air at ambient temperature and medium temperature to compensate for leakage rates through the door sample up to 55 m 3 /h. ISO 5925-1:2007(E) 4 ISO 2007 All rights reserved6 Instrumentation 6.1 Differential pressure A suitable
37、instrument shall be provided to measure the static differential pressure between the inside and outside of the test chamber. The pressure head shall be mounted in the test chamber at the centre of the test specimen (100 10) mm from the inside face of the test chamber. The pressure-measuring equipmen
38、t shall be capable of measuring differential pressures with an accuracy of 5 Pa or 10 % of the measured value, whichever is lower. Barometric pressure shall be measured to an accuracy of 5 %. 6.2 Air temperature For the medium-temperature test, 12 thermocouples shall be used to monitor and control t
39、he temperature inside the test chamber. The thermocouples shall be arranged in four horizontal rows, with three thermocouples in each row. The end thermocouples in each row shall be in line with the sides of the door frame or jamb, and the middle thermocouple in line with the door central axis. The
40、top row shall be 150 mm below the edge of the free opening and the bottom row 150 mm above the sill level. The other two rows shall be equidistant between the top and the bottom rows. The hot junctions shall be positioned (100 10) mm from the door face. The thermocouple shall be of bare-metal type w
41、ith a wire diameter of 0,5 mm, or steel-sheathed type with the overall diameter not exceeding 1,0 mm. The temperature-measuring equipment shall be capable of measuring temperatures up to 250 C with an accuracy of 5 C. 6.3 Air flow Suitable instrumentation shall be provided to measure the volume, V t
42、 , and the temperature, T a , of air supplied to the apparatus to compensate for the total leakage. The apparatus shall be able to measure leakage rates up to at least 55 m 3 /h with an accuracy of 1 m 3 /h. 7 Test specimen 7.1 Number As doors are usually of asymmetrical construction, leakage tests
43、shall be carried out from both sides for full evaluation. For medium-temperature tests, this will require two separate test specimens (door samples). One specimen may be sufficient if the door is absolutely symmetrical in design, or in the special case where information on leakage from only one side
44、 is required for limited application. The test report shall clearly indicate the basis for the use of a single specimen. 7.2 Size The door and shutter assembly (test specimen) shall be full size, or the largest size that can be accommodated in the test frame to be mounted on the face of the test app
45、aratus, normally 3 m 3 m. 7.3 Construction The door and shutter assembly (test specimen) construction and finish shall be fully representative of that intended to be used in practice. Any seal used in the door and shutter assembly or between the assembly and the associated construction shall be iden
46、tical to that intended for application in practice. 7.4 Conditioning The general requirements of ISO 834-1 for conditioning shall be followed. Assemblies made entirely of non- hygroscopic materials, such as metal, glass, etc., do not require conditioning. ISO 5925-1:2007(E) ISO 2007 All rights reser
47、ved 5 7.5 Pre-test analysis The physical characteristics of the door and shutter assembly (test specimen), such as size, thickness, material specification, shall be determined before the test to check the construction of the assembly against the manufacturers specification and to allow adequate desc
48、ription of the tested assembly. All gaps through which smoke can leak shall be measured and recorded. Generally, these gaps are between the edge of the door leaf/leaves and the door frame, between door leaves, at the sill level, and curtain and wall, barrel and wall, etc. A full description shall be
49、 given of the conditions prevailing at each edge, and the presence and the nature of any seals. The force required to open the swinging door leaf or leaves shall be determined in accordance with the relevant International Standards. If any latches are fitted, these shall be disengaged during the test. 8 Test procedure 8.1 Setting-up procedure 8.1.1 The door and shutter assembly (test specimen) shall be mounted as in practice, in an associated or supporting construction, in accordance with the manufa
