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 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 revision For
undated references the latest edition of the publication
referred to applies
prEN 1883, Feather and down Ð Sampling in view of
tests.
EN 20139, Textiles Ð Standard atmospheres for
conditioning and testing (ISO 139:1973).
EN 20187, Paper, board and pulps Ð Standard
atmosphere for conditioning 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 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 prepared, 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 regard 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 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 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 become 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 vacuum 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 Figure 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 distance 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
Trang 8Page 4
EN 12130:1998
BSI 1998
6 Preparation 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 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 150 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 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 by 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 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 blowing 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 the 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 by 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 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 = H 3 a
m 3 1000 where:
H is the 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 specimens
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 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 reproducibility 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:
Ð the reference to this standard;
Ð the description of the test material;
Ð the mass of the test specimen in grams;
Ð the filling power in millimetres;
Ð the massic volume, in cubic centimetres per grams, if required;
