34、od 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 length l dimension of the test specimen parallel to the longer linear dimension of major surface of the original product 3.2 width b linear dimension of the major surface of the test specimen
35、, measured at right angles to the length 3.3 thickness d linear dimension measured perpendicularly to the length and width plane 4 Principle The changes in linear dimensions are determined which occur when the test specimens have been conditioned, subjected to specified environments for a given peri
36、od, and then reconditioned. 5 Apparatus 5.1 Temperature controlled or temperature and humidity controlled chamber, capable of maintaining the test specimens within the specified conditions and within the limits specified in 7.2. 5.2 Measuring instruments, capable of measuring linear dimensions of te
37、st specimens in accordance with EN 12085, to an accuracy of 0,1 mm. BS EN 1604:2013EN 1604:2013 (E) 6 6 Test specimens 6.1 Dimensions of test specimens The thickness of test specimens shall be the original product thickness. The test specimens shall be squarely cut and have a side length of (200 1)
38、mm. If larger dimensions are used, the accuracy shall be as given in 5.2. 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. If the number is not specified, then at least three test specimens shall be tested for each set of chosen condit
39、ions. In the absence of a product standard or any other European Technical Specification, the number of test specimens may be agreed between parties. 6.3 Preparation of test specimens The test specimens shall be cut so that they are representative of the full size product. Any surface skins, facings
40、 and/or coatings shall be retained. Length and width directions shall be marked on the test specimens. 6.4 Conditioning of test specimens The test specimens shall be conditioned to equilibrium with an atmosphere at (23 2) C and (50 5) % relative humidity. A test specimen is considered to be conditio
41、ned when changes in length and in width, measured according to 7.2, between two consecutive measurements at a time interval of two weeks, are less than 0,1 %. Other time intervals may be defined in the relevant product standard or any other European Technical Specification. 7 Procedure 7.1 Test cond
42、itions Condition the test specimens in accordance with 6.4. 7.2 Test procedure In the same atmosphere as used for conditioning, determine the initial length and width of each test specimen (l0and b0) by taking readings at three positions (l01, l02, l03and b01, b02, b03) and the initial thickness (d0
43、) at five positions (d01, d02, d03, d04, d05) as shown in Figure 1, using the appropriate methods described in EN 12085, to an accuracy of 0,1 mm. Expose a set of test specimens to each of the conditions specified in the relevant product standard. In the absence of such a specification, test conditi
44、ons may be agreed between parties chosen from the following: For a specified temperature without a specified relative humidity: (40 3) C BS EN 1604:2013EN 1604:2013 (E) 7 (30 3) C (+40 2) C (+60 2) C For a specified temperature with a relative humidity specified in the range 30 % to 90 %, to an accu
45、racy of 5 % relative humidity: (+20 2) C (+23 2) C (+60 2) C (+70 2) C Other conditions may be used. Lay the test specimens horizontally or place them vertically in the test chamber, not less than 25 mm apart, on a rigid wire mesh or perforated metal plate such that a substantial amount of free air
46、is circulated around the test specimens. The test specimens shall not be exposed to the direct radiation from any heating elements. The preferred duration of exposure is (24 1) h or (48 1) h. Other exposure times may be as specified in the relevant product standard or any other European Technical Sp
47、ecification or may be agreed between parties. Remove the test specimens after exposure to the test atmosphere and expose them for a further (3 1) h at (23 2) C and (50 5) % relative humidity. Determine the final length, width, and thickness of the test specimens (ltand btand dt) by taking readings (
48、lt1, lt2, lt3and bt1, bt2, bt3and dt1, dt2, dt3, dt4, dt5f) at the same positions as for the initial measurements (see Figure 1). Examine the test specimens visually. If requested in the relevant product standard or any other European Technical Specification, the test specimens may be re-exposed to
49、the test conditions for periods of 7 days and the dimensions re-determined at the positions shown in Figure 1, at the end of the requested periods.
