5 Atmosphere for conditioning and testing
The standard atmosphere for conditioning and testing of textiles shall be one of those specified in ISO 139.
6 Sampling and preparation of soiled pellets and test specimens
6.1 Preparation of soiled pellets
Place (3� 0,1) g of the preferred soiling compound C5 and 1 000 g of polyamide pellets in the mixing container.
Secure the lid and place the mixing container on the driving system (4.1) for 20 min. to ensure a homogeneous
mixture of the soil and the pellets.
To simulate particular use areas it may be necessary to adjust the type and/or quantity of soiling compound
NOTE If large quantities of soiled pellets are prepared (e.g. more than 2 000 g) they should kept in an airtight container to
ensure that no loss of moisture from the mixture occurs, and the supply should not be allowed to dwindle below 25 % of the
original quantity prepared.

6.2 Sampling
Select test specimens of each textile floor covering being tested in accordance with ISO 1957.
NOTE Colour and design play a large part in the assessment and this should be borne in mind when selecting test
specimens and when assessing.
6.3 Number and dimensions
Cut a minimum of two test specimens per textile floor covering measuring a minimum of (125� 1) mm in the
direction of manufacture by (200� 2) mm wide. Mark an arrow in the direction of manufacture or, in the case of pile
carpets, in the direction of the pile lay on the back of the test specimen. Allow the test specimens to condition in the
standard atmosphere (clause 5), flat, singly and with use-surface uppermost, for a minimum of 24 h.
6.4 Preparation of test specimen
6.4.1 Attach double-sided adhesive tape (4.9) along each edge, across the ends and at each specimen cross
junction of the specimen backing sheet. Mount the test specimens and the control textile floor covering (4.11), use
surface uppermost, allowing a (5� 1) mm gap at each end and an (8� 1) mm gap between specimens to allow for
the specimens to remain attached when the specimen backing sheet is curved to fit the internal circumference of
the drum. Check to ensure that each test specimen is flat to the specimen backing sheet and in the direction of
manufacture when it is curved to the inside drum diameter. If the test specimens are not properly secured adjust
the test specimen accordingly. When test specimens of differing thickness are tested together, the difference in
thickness of the adjacent test specimens shall not exceed 1 mm.
6.4.2 Use the suction cleaner (4.7) to remove loose fibre from the test specimens, using a total of four strokes,
two strokes in each direction of manufacture or, in the case of pile carpets two against and two with the direction of
thepilelay.
6.4.3 In the case of cut pile test specimens align the pile in the direction of natural pile lay by using the ruler
(4.10). Move the ruler once across the test specimen in the direction of pile lay, applying slight pressure.
7 Procedure
7.1 If using colour measurement for assessment, locate the measuring template (4.12.3) on the test specimen
and, using the colour measuring equipment (4.12.1), measure the colour of the test specimens in six places.
Record these values.
7.2 Ensure that the inside of the drum (4.1) and the chrome alloy steel balls (4.4) are clean.
7.3 Fit the mounted test specimens into the clean drum, ensuring that the backing sheet fits tightly and lies
smoothly around the internal circumference.
7.4 Place (1 000� 10) g of chrome alloy steel balls (4.4) and (250� 2) g of soiled pellets into the drum and
secure the lid.
7.5 Place the drum on the driving system, start the machine and allow the drum to rotate for 30 min. When the
test is completed stop the machine, remove the drum and sit it upright.
7.6 Remove the backing sheet (4.8) with the test specimens and carefully clean the test specimens by suction
with the suction cleaner (4.7) to remove loose surface soil and fibre, using a total of four strokes in each direction of
manufacture or, in the case of pile carpets, two against the direction of the pile lay and two with. In the case of cut
pile carpets, ensure that the last stroke of the suction nozzle is in the direction of the pile lay. Move the straight
edged rule (4.10) across the pile in the direction of the pile lay, applying slight pressure to align the pile.
7.7 Using the magnet (4.5) remove the chrome alloy steel balls (4.4) from the drum.
7.8 With the suction cleaner (4.7), vacuum the used soil pellets from the inside of the drum. Clean the inside of
the drum with a damp cloth.
