Mer standards included in the package are EN 1121, and EN 12219. Although the Englkh I
4、aiguage versions of these European Standards will be adopted as British Standards as they become available, the existing British Stan- for doors WU be retained, but only untii such time that the complete package of European Standards becomes available. The original group of British Standards wiii th

This European Standard replaces EN 43:1985, Methods of tesng doors - Behaviour under humidi
17、ty variations of door leaves placed in successive uniform climates. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2000, and conflicting national standards shall be withdrawn at the latest
18、 by August 2000. According to the CENICENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherl
19、ands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This European Standard has been prepared taking into account IS0 6444 and EN 43. This draft is one of a series of standards for doors. 1 SCOPE This European Standard describes the method which is to be used to test the behavi
20、our under humidity variations of door leaves placed in successive uniform climates. This standard can be applied to all door leaves, (e.g. solid doors, hollow core doors, panelled doors and glazed doors), which are nominally flat and rigid, and which contain hygroscopic materials can might influence
21、 their behaviour during this test. 2 NORMATIVE REFERENCES This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references,
22、 subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 951 EN 952 prEN 1251 9: 1996 Door leaves - Method for measur

24、rior to the test, condition the door leaf for at least 7 days in one of these two standard climates: Temperature (20 f 2) “C; Temperature (23 f 2) OC; Relative Humidity (65 f 5) %; Relative Humidity (50 f 5) %. 5 APPARATUS Climate chambers capable of maintaining controlled temperature and humidity.
25、Suitable supporting device for holding the door leaf in a vertical position without imposing any restraint that might affect the development of deformation. Apparatus for measuring general and local flatness in accordance with EN 952. Apparatus for measuflng height and width in accordance with EN 95
26、1. Apparatus for weighing the specimen in accordance with 6.1, 6.2,6.3, 6.4 and 6.5 6 TEST PROCEDURE 6.1 Initial measurement After conditioning the door leaf in accordance with clause 4, measure its height and width in accordance with EN 951, its general flatness in accordance with EN 952, and its m
27、ass. Also measure local flatness in accordance with EN 952 if required. 6.2 Exposure to high humidity Place the door leaf in a climate defined by: Temperature (23 f 2) OC; Relative Humidity (85 f 5) %. The mean values of temperature and relative humidity shall be maintained as close as practicable t
28、o the nominal values: the tolerances are permitted only for purposes of regulation. The duration of exposure to this climate shall be 7 days for doors without applied finish, and 21 days for all other doors. The test may be stopped before the end of the period specified above, if two successive meas
29、urements of general flatness taken at 2 day intervals do not differ by more than 1 % or if the specimen has reached hygroscopic equilibrium (difference in mass between two successive weighings at 2 day intervals less than Oll % of the initial mass). If the test house stops the test before the full d
30、uration of exposure, it shall give reasons for its decision. 6.3 Measurement after exposure to high humidity Remeasure the height and width, the general flatness and the mass of the door leaf. Also remeasure local flatness if required. OBSI 07-2000 Page 4 EN 1294:2000 6.4 Exposure to low humidity Pl
31、ace the door leaf in a climate defined by: Temperature (23 i: 2) OC; Relative Humidity (30 I 5) %. The mean values of temperature and relative humidity shall be maintained as close as practicable to the nominal values; the tolerances are permitted only for purposes of regulation. The duration of exp
32、osure to this climate shall be 7 days for doors without applied finish, and 21 days for all other doors. The test may be stopped before the end of the period specified above, if two successive measurements of general flatness taken at 2 day intervals do not differ by more than I % or if the specimen
33、 has reached hygroscopic equilibrium (difference in mass between two successive weighings at 2 day intervals less than 0,l %). If the test house stops the test before the full duration of exposure, it shall give reasons for its decision. 6.5 Measurement after exposure to low humidity Remeasure the h
34、eight and width, the general flatness and the mass of the door leaf. Also remeasure local flatness if required. 7 EXPRESSION OF RESULTS The results shall be expressed in terms of absolute value and variations in the measurements of the height, width, general flatness, local flatness and mass. The ac
35、curacy of the measurements shall be as prescribed in EN 951 and EN 952. 8 TESTREPORT The test report shall include the following information: a) all necessary details to identify the door leaf; b) all relevant details concerning the type, dimensions, shape and constructional details of the door leaf
