28、ml, dried at (105 2) C (in accordance with ISO 3819). 5.10 Drying oven, capable of being controlled at a temperature of (105 2) C. 6 Conditioning and testing Test specimens of a representative part of the laboratory bulk sample shall be conditioned for a minimum period of 24 h in accordance with EN

29、20139 and the temperature and relative humidity shall be measured in accordance with EN 20187. 7 Procedure 7.1 Take one conditioned test specimen of mass from 4 g 0,05 g to 5 g 0,05 g. 7.2 Put the conditioned test specimen into the extraction thimble, which is placed in the Soxhlet extractor. Attach

30、 the condenser and extraction flask, and put enough solvent to maintain siphoning. Place the connected flask in the waterbath or on the hot plate so that satisfactory siphoning occurs, at the rate of not less than 6 cycles per hour and then extract the individual sample. 7.3 Extract the test specime

31、n for not less than 20 siphonings. Filter the content of the extraction flask through a sintered filter or fat free paper filter into a tared beaker, remove the bulk of the solvent by distillation, dry to constant mass in a well ventilated oven at (105 2) C. 7.4 Repeat the operations in 7.1 to 7.3 o

33、ms; B is the mass of the beaker, in grams; C is the mass of the conditioned test specimen, in grams. The result is expressed as the average of at least two determinations, rounded to one decimal place. 9 Test report The test report shall include at least the following information: the reference to t

34、his standard; date and place of testing; identification mark of the individual sample tested; the mean result to one decimal place in accordance with 8; any departure from the procedure and any other circumstances that can have affected the result.
