18、age 3 EN 1161 : 1996 BSI 1997 1 Scope This European Standard specifies a procedure to determine the moisture content of an individual sample of feather and down. 2 Definitions For the purposes of this standard the following definition applies: moisture content The ratio between the loss of mass of a

19、 test specimen by drying at (105 2) C and the initial mass of the same test specimen. 3 Principle The moisture content is determined by drying the test specimen at (105 2) C until a constant mass is obtained. The test specimen is weighed before and after this operation. 4 Apparatus 4.1 An analytical

20、 balance, (with sensitivity of 0,1 mg). 4.2 Weighing containers, water-vapour proof and with tightly fitting lids. 4.3 Oven, capable of being controlled at (105 2) C, and suitably ventilated. 4.4 Tongs. 4.5 A desiccator, with desiccating agent. 5 Preparation of the test specimen A representative par

21、t of the laboratory bulk sample shall be drawn and mixed. From this, two test specimens of about 5 g weighed to an accuracy of 1 mg each shall be drawn, taking care to avoid humidity variation, and placed into containers (4.2). 6 Procedure 6.1 The uncovered container and the lid shall be placed for

22、2 h 10 min in the oven at a temperature of (105 2) C. The container shall then be covered, and using clean tongs quickly transferred to the desiccator. After cooling to room temperature for not less than 1 h the covered container shall be weighed. This procedure shall be repeated until a constant ma

23、ss, within 1 mg, is obtained. 6.2 A representative test specimen of about 5 g weighed to an accuracy of 1 mg shall then be transferred as quickly as possible to the pre-dried container taking care to avoid humidity variations. The container shall be covered with a lid and weighed to an accuracy of 1

24、 mg. 6.3 The containers and the lids shall be placed separately in the oven and dried at (105 2) C. After drying for 1 h 10 min the container and the lid shall be transferred using clean tongs to the desiccator, and allowed to cool for not less than 1 h. After cooling to room temperature, the contai

25、ners with the lids shall be transferred using clean tongs to the analytical balance and weighed. The heating, cooling and weighing cycle shall be repeated until the mass of the container with a dried lid is constant to within 1 mg. 6.4 Repeat the procedure on a second test specimen. 7 Expression of

26、results The moisture content expressed as a percentage is calculated as follows: M c %= 3100 A2 B A2 C where M c is the moisture content in percent; A is the mass of the container with lid and undried individual sample; B is the mass of the container with lid and dried individual sample; C is the ma

27、ss of the container with a dried lid. All masses shall be expressed in grams, to three decimal values. Calculate the mean of the two determinations with the approximation to the nearest integer. 8 Test report The test report shall include at least the following information: the reference to this sta

28、ndard; date and place of testing; identification mark of the individual sample tested; the arithmetic mean result to the nearest integer in accordance with clause 7; any departure from the procedure and any other circumstances that may have affected the result.4 blank BSI 1997 BS EN 1161 : 1997 List
