19、nition For the purposes of this standard the following definition applies. dimensional stability The variation of the distance between marks previously made on the test piece after treatment in humid air under specified conditions. 3 Apparatus 3.1 A sliding calliper gauge, or equivalent device, e.g.
20、 a table with comparators and stop unit, of accuracy 0,05 mm. 3.2 A smooth, flat surface, with dimensions larger than those of the tiles, e.g. a plate of thickness $ 10 mm. 3.3 A rigid plate, squared and finished, with dimensions 5 mm to 10 mm less than those of the test pieces. The mass per unit ar
21、ea of the plate shall be approximately 20 kg/m2(e.g. steel of thickness 2,5 mm or duralumin of thickness 7 mm). 3.4 Humidity cabinet, or similar device, capable of maintaining test pieces at 23 C and 80 % relative humidity. 4 Sampling and preparation of test pieces Take a representative sample from
22、the available material. Take five tiles from the sample as test pieces. Where a pack of tiles comprises the sample, ensure that the first and last tiles are not selected as test pieces. 5 Conditioning Condition the tiles at a temperature of (232) C and relative humidity (505) % for a minimum of 24 h
23、. 6 Procedure Scribe three marks along each side of the tile, two approximately 10 mm from the perpendicular edges and the third equidistant from the first two. Place the tile on the flat surface with the squared plate on top. Take three measurements of the marked distance between the opposite sides
24、. Expose the tile to an atmosphere of (232) C and (805) % relative humidity in the humidity cabinet (3.4) for (240,5) h. Repeat the measurements within 10 min of removal from the humidity cabinet. 7 Calculation and expression of result For each tile, calculate the mean value of the three relevant me
25、asurements in each direction, before and after exposure at 23 C and 80 % relative humidity. Calculate the change from the initial length. Calculate the mean value for the five tiles for each direction expressed as a percentage to the nearest 0,01 %. 8 Test report The test report shall contain the fo
26、llowing information: a) a reference to this standard, i.e. EN 669; b) a complete identification of the product tested, including type, source, manufacturers reference numbers; c) previous history of the sample; d) the mean value of dimensional change for each direction; e) any deviation from this st
27、andard which may have affected the results.
