Scope Definitions Principle Preparaton of the test specimen Procedure Expression of results Test report page 3 3 3 3 3 3 3 3 O BSI 1997 1 Scope This European Stanard specifies a procedure to determine the moisture content of an individual sample of feather and do
18、wn. 2 Definitions For the purposes of this standard the following definition applies: moisture content The ratio between the loss of mas of a test specimen bydryingat(105f2)“C andtheinitialmassofthe same test specimen. 3 Principle The moisture content is determined by drymg the test specimen at (105
19、 f 2) “C until a constant mass is obtained The test specimen is weighed before and after this operation. 4 Apparatus 4.1 An analyticai balance, (with sensitivity of 0,l mg). 4.2 Weighing containers, water-vapour proof and with 4.3 Oven, capable of being controlled at (105 f 2) C, and suitably veniak
20、d. 4.4 Tongs. 4.6 A desiccator, with desiccating agent. tightly fitting lids. 6 Preparation of the test specimen A representative part 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 dram, taking care to
21、avoid humidity variation, and placed into containers (4.2). 6 Procedure 6.1 The uncovered container and the lid shall be placed for 2 h f 10 min in the oven at a temperature of (105 f 2) “C. The container shall then be covered, and using clean tongs quickly transferred to the desiccator. After cooli
22、ng to room temperature for not less than 1 h the covered container shail be weighed. This procedure shall be repeated until a constant mass, 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 th
23、e pre-dried container taking care to avoid humidity VanationS. The container shall be covered with a lid and weighed to an accuracy of 1 mg. Page 3 EN 1161 : 1996 6.3 The containers and the lids shall be placed separately in the oven and dried at (105 f 2) “C. After drymg for 1 h 10 min the containe
24、r and the lid shall be transferred using clean tongs to the desiccator, and ailowed to cool for not less than 1 h. After cooiing to room temperature, the containers with the lids shall be transferred using clean tongs to the analytical balance and weighed The heating, cooling and weighing cycle shal
25、l 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 results The moisture content expressed as a percentage is calculated as follows: where M, is the moisture content in percent; A is the mass o
26、f the container with lid and undried individual sample; B is the mass of the container with lid and dried individual sample; C is the mass 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 approxim
27、ation to the nearest integer. 8 Test report The test report shaU include at least the following information: - the reference to this standax4 - date and place of testing; - identification mark of the individual sample test - any departure from the procedure and any other circumstances that may have
