9.1 Select the washing procedure to be used from those given in Annex B for a type A reference washing machine, from Annex 0 for a type B reference washing machine, or from Annex F for a type C reference washing machine.
9.2 Weigh the (indMdual) specimens or made-up articles or garments before washing if measurement of weight loss is required or if they are to be tumble dried.
9.3 Place the material to be washed in the washing machine (see 5.1.1 to 5.1.3) and add sufficient ballast
(see 5.6) to make a total air-dry material load of the mass shown in 8.1 using the washing procedure selected.
The specimen and the ballast shall be evenly mixed before it is loaded into the reference machine.
a) In Reference washing machines Type A, add (20 ± 1) g of the reference detergent 2. 3 or 6 directly into the dispenser.
b) In Reference washing machines Type B fill the machine with water at the selected temperature, then add
(66 ± 1) g of reference detergent 1 or add (100 ± 1) g of reference detergent 5, or if reference detergent 2
or 3 is used, add the appropriate amount to provide good running suds having a height of not more than
(3 ± 0,5) cm at the end of the washing cycle.
C) In reference machines Type C, fill the machine with water at the selected temperature, then add 1,33 gIl of reference detergent 4 directly into the dispenser.
d) See Table 1 for a summary of the reference detergent dosage.
9.4 After the washing procedure has been completed, remove the test specimen(s) carefully, ensuring that they are neither stretched nor distorted, and dry according to one of the drying procedures described in Clause 10.
10 Drying procedure
10.1 Open-air dry
At the end of the selected washing procedure, immediately remove the material and follow the selected drying procedures A to F. In the case of drip drying, the washing procedure shall be finished without spinning; this means taking out the material before final spinning.
10.1.1 Procedure A — Line dry
Remove the specimen from the washing machine and hang each hydro-extracted specimen unfolded with the fabric length In the vertical direction to avoid distortion. Suspend the test specimen from a line, in still air under ambient conditions.
The warp or wale direction of the material specimen shall be vertical. Made-up articles shall be suspended in the direction of use.
NOTE For subsequent testing. the drying may be carried out in a conditioned atmosphere according to ISO 139
10.1.2 Procedure B — Drip line dry
Follow the procedure in 10.1.1 without extracting the water.
NOTE For subsequent testing. the drying may be carried out in a conditioned atmosphere according to ISO 139.
10.1.3 Procedure C — Flat dry
Remove the specimen from the machine and spread out each hydro-extracted specimen on a horizontal screen drying rack (see 5.5) or perforated surface; remove the wrinkles by hand without stretching or distorting. Allow the specimen to dry in still air in ambient conditions.
NOTE For subsequent testing. the drying may be carried out in a conditioned atmosphere according to ISO 139.
10.1.4 Procedure D — Drip flat dry
Follow the procedure in 10.1.3 without extracting the water.
10.1.5 Procedure E — Flat press
Remove the specimen from the washing machine and place the specimen on the fiat bed of the press (see 5.3). Smooth out heavy wrinkles by hand and lower the head of the press, which shall be set at a temperature suitable for the specimen to be pressed, for one or more short periods as required to dry the specimen. Record the temperature and pressure used.
10.2 Tumble dry
10.2.1 Procedure F — Tumble dry
At the end of the selected washing procedure, immediately remove the load and place the specimens and the ballast in the tumble dryer (see 5.2). Tumble dry the load as specified in either 10.2.2. 10,2.3 or 10.2.4.ISO 6330 pdf download.
