19、e for determining the filling power (massic volume). This method is applicable to finished down and/or feather, fit for or constituting filled manufactured articles (e.g. anoraks, quilts, etc.) 2 Normative references This European Standard incorporates by dated or undated reference, provisions from
20、other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or
21、 revision. For undated references the latest edition of the publication referred to applies. prEN 1883, Feather and down Sampling in view of tests. EN 20139, Textiles Standard atmospheres for conditioning and testing (ISO 139:1973). EN 20187, Paper, board and pulps Standard atmosphere for conditioni
22、ng and testing and procedure for monitoring the atmosphere and conditioning of samples (ISO 187:1990). 3 Definitions For the purposes of this standard the following definitions apply. 3.1 filling power (fp) height of the volume occupied by filling material subjected to a specific pressure, expressed
23、 in millimetres NOTE The volume comprises internal pores of elements and pore spaces between elements. 3.2 massic volume volume occupied by a given mass of filling material, when subjected to a specific pressure; it is expressed in cubic centimetres per gram 4 Principle A test specimen, suitably pre
24、pared, having a specified mass is placed in a cylinder and the material is aerated by blowing for a set period. Pressure by way of a platen is then applied to the filling material at a constant speed and after a stipulated time the level of the platen is noted. The massic volume is calculated with r
25、egard to the height and the known diameter of the graduated cylinder. 5 Apparatus It is allowed to use any kind of apparatus on condition that it gives the same results, within experimental error, like the one described below. These alternative apparatus should be of such design to give satisfactory
26、 performance, particularly for a good air blowing of the test specimen. 5.1 Tester (see Figure 1) which consists of: 5.1.1 Cylinder, with flat bottom standing on a base capable of being levelled by adjustable legs, with internal diameter of (289 1) mm and (500 5) mm high. The cylinder shall be made
27、from smooth, antistatic and transparent material (e.g. acrylic). 5.1.2 Plunger and measuring rod, of mass giving a pressure of (14,8 0,2) Pa. The plunger, suspended by measuring rod, with diameter (282 3) mm shall have its underside flat and smooth and made of a rigid material, so that it does not b
28、ecome deformed in use. The measuring rod, marked in millimetres, shall be at zero when the plunger is resting on the bottom of the cylinder. Instead of the measuring rod, it is possible to use any kind of device on condition that the pressure exerted on the material is of (14,8 0,2) Pa. NOTE A vacuu
29、m cleaner can be used as a suitable blower. 5.1.3 Cover, mounted in a frame which fits over the cylinder, consists of a wire screen of nominal aperture size 180 mm and a wire diameter 125 mm (see ISO 3310-1). In the centre of the cover is inserted a blow nozzle (5.1.4). 5.1.4 Blow nozzle, (see Figur
30、e 2) equipped with an adjustable valve in order to regulate the amount of the air injected. 5.1.5 Device regulating the descent of the plunger and measuring rod at (520 20) mm/min. 5.2 Blower, with a suitable tube connected to its exhaust vent and capable of guaranteeing an air flow, measured at a d
31、istance of 400 mm from the inlet nozzle, of (310 50) l/min. 5.3 Stop watch 5.4 Balance, sensitive to 0,05 g 5.5 Sample preparation box of wire net, having dimensions which will contain a sample up to at least 50 g with the height of material less than 150 mm.Page 4 EN 12130:1998 BSI 1998 6 Preparati
32、on and conditioning of sample and equipment 6.1 A mass of at least 50 g is obtained from the material to be tested, in accordance with the procedure described in prEN 1883. The sample is placed in an adequate container (substituting for the cylinder in 5.1.1) and the cover is applied. With the valve
33、 aperture set for maximum air flow, air is blown into the container for (60 5) s. 6.2 The sample is then removed from the container and conditioned in the atmosphere as defined in EN 20139, and controlling the relative humidity in accordance with EN 20187 by storing it loose to a maximum height of 1
34、50 mm in sample preparation box (5.5) for at least 48 h. 6.3 It is necessary to wash the cylinder after 30 measurements (15 test specimens) with warm water prepared with anionic-active detergent (concentration: 0,4 ml/l) followed by two rinses with cold distilled water. To ensure reliability of the
35、procedure, and if doubtful of the influence of static electricity on the result, proceed as follows. Record the height of the plunger at the end of the first test and leave the plunger in place for at least 2 h. Measure again the height of the plunger. If the new measurement differs from the first b
36、y more than 2 cm, repeat the procedure starting at 6.2. 7 Procedure 7.1 Conditioning is carried out according to EN 20139 and the temperature and relative humidity are measured according to EN 20187. 7.2 Ensure that the cylinder is vertical by adjusting the legs and that the measuring rod is at zero
37、 when the plunger is standing on the bottom of the cylinder. 7.3 Weigh out (20,0 0,1) g of two test specimens each extracted from the sample (6.1) and place the first test specimen in the cylinder and apply the cover. 7.4 The test specimen is loosened by blowing for (60 5) s. It is essential that bl
38、owing is halted immediately. 7.5 Insert the plunger and measuring rod into the top of cylinder and lower mechanically or manually towards the test specimen at a constant speed of (520 20) mm/min until the plunger is standing horizontally or almost horizontally on the test specimen. If not, repeat th
39、e blowing on the same test specimen. 7.6 Read from on the measuring rod the height of the material after a period of (60 2) s. As far as possible, position the plunger in the centre of the cylinder for the whole test. 7.7 Repeat steps 7.4, 7.5 and 7.6 using the same test specimen which is loosened b
40、y blowing for (7 3) s, as described above prior to each reading. Note the average of the values, in millimetres. 7.8 Repeat steps 7.3 to 7.7 for the duplicate test specimen. 8 Calculation and expression of results 8.1 Filling power: Recorded in millimetres. Calculate the mean of the results obtained
41、 on the two test specimens and report them with the symbol, fp. 8.2 Massic volume 8.2.1 From the mean results of fp obtained for each test specimen, calculate the massic volume (V) in cubic centimetres per gram with the approximation to the first decimal with the formula: V= H3a m31000 where: H is t
42、he mean height of two determinations (7.7), obtained on one test specimen, expressed in millimetres; a is the test surface area of the cylinder expressed in square millimetres; m is the mass of the test specimen, in grams. 8.2.2 Calculate the average of the bulk density obtained for the two test spe
43、cimens. 9 Precision of the method Based on data from one interlaboratory test carried out by eleven laboratories on five different samples and two determinations for sample, and from another interlaboratory test carried out by ten laboratories on nine samples and two determinations for a sample, the
44、 following precision data were found for the filling power: Repeatability: The 95 % probability of the repeatability limit (r) for the difference between two test results within a single laboratory was about 3 mm for different filling samples. Reproducibility: The 95 % probability of the reproducibi
45、lity limit (R) for the difference between two test results from different laboratories was about 15 mm for different filling samples. 10 Test report The test report shall include at least the following information: the reference to this standard; the description of the test material; the mass of the
46、 test specimen in grams; the filling power in millimetres; the massic volume, in cubic centimetres per grams, if required; any deviation from the standard procedure and any other circumstances that may have affected the result.Page 5 EN 12130:1998 BSI 1998 Dimensions in millimetres Figure 1 Filling
