14、ying quantities of oils and fats. It is suspected that adding mineral oil has the effect of binding impurities into the feathers and down, giving the impression of a cleaner product. 1 Scope This European Standard specifies a method for determining the amount of solvent soluble matter in dichloromet

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 specimen for not less than 20 siphonings. Filter the content of the extraction flask th

25、rough 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 f 2) OC. 7.4 Repeat the operations in 7.1 to 7.3 on the second test specimen.

26、ichloromethane soluble matter content, M, as a percentage, is calculated as follows: A-B C M, =- 100 where A is the mass of the beaker containing the residue, in grams; B is the mass of the beaker, in grams; C is the mass of the conditioned specimen, in grams. The result is expressed as the mean for

27、 at least two determinations, to one decimal place. 9 Test report The test report shall include at least the following information: - the reference to this 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.
