36、ty BS EN 1603:2013EN 1603:2013 (E) 6 4 Principle Measure length, width and deviation from flatness of the test specimens at several time intervals under normal laboratory conditions until relative stability has been achieved. Dimensional stability is determined using one or more of the following met

38、od A: Measuring equipment as defined in EN 822. Method B: A frame fixed on a flat reference surface with a dial gauge of 0,01 mm accuracy or any device (optical, electrical etc.) which has an accuracy of 0,1 mm/m (see examples in Figure 1 and Figure 2); and either Method B1: Metal plates of at least
39、 20 mm in diameter (see Figure 1). The actual diameter is to be chosen so that the pressure exerted by the dial gauge is less than 2 kPa; or Method B2: Metal wire (see Figure 2). Method C: Measuring equipment as defined in EN 825. Any test equipment which provides the same result to at least the sam

Method A: The test specimen shall be the full size product. Method B1: 500 mm 500 mm or, if less than 500 mm 500 mm, as large as possible. I

Method C: The test specimen shall be the full size product. 6.2 Number of test specimens When testing full size products, the number of test specimens shall be as specified in the relevant product standard.

If test specimens are not the full size products, the length and width directions shall be marked on them. The method of selection of the test specimens
45、 shall be as specified in the relevant product standard. In the absence of a product standard or any other European Technical Specification, the method of selection may be agreed between parties. 6.4 Conditioning of test specimens The test specimens shall be conditioned for at least 24 h at (23 2) C
46、 and (50 5) % relative humidity. 7 Procedure 7.1 Test conditions Testing shall be carried out at (23 2) C and (50 5) % relative humidity. The test specimens shall be conditioned, either vertically or horizontally, with their major faces exposed to the test atmosphere (e.g. supported by a wire mesh a

BS EN 1603:2013EN 1603:2013 (E) 9 In absence of a product standard or any other European Technical Specification, the method
48、 to be used may be agreed between parties. Measure the length, the width and the deviation from flatness at the start of the test (l0, b0, S0) and thereafter at time intervals of 28 days (lt, bt, St), with a minimum of 28 days of total test duration. If a more accurate deformation curve is required,
49、 measurements may additionally be performed at 1 day, 3 days, 7 days, and 14 days. Continue measurements until the change in dimensions between the last two measurements is less than 10 % of the total change permitted. The total change permitted, , is normally specified in the relevant product standard. In the absence of such a specification, may be agreed between parties. The accuracy of the measuring equipment shall be eq
