NOTE 1 AATCC reference detergent WOB can only be used in top-loading type B washers. NOTE 2 The nominal composition of AATCC reference detergent WOB is given in annex A. 3.4 ECE reference detergent (without optical brightener).

This can be used except when colour fastness is being assessed. NOTE 1 IEC reference detergent can be used in all machines. NOTE 2 The nominal composition of IEC reference detergent is given in annex B. 3.6 Sodium perborate tetrahydrate (NaBO3·4H2O). 3.7 Loading fabric: Pieces consisting of two layers of knitted 100 % polyester fabric or woven cotton/polyester fabric, having a mass per unit area that approximates the fabric under test to within ± 25 %. Each piece shall measure 30 ± 3 cm × 30 ± 3 cm sewn together at the edges. 3.8 Electrically (dry heated) heated flat-bed press NOTE If this method of drying is used, the type of press shall be specified between the interested parties. 3.9 Facilities for drip or line drying 3.10 Screen drying racks, of 16 mesh stainless steel or plastics (see 6.3). 4 Test specimens The number of specimens to be subjected to the washing and drying procedures specified in this International Standard will be determined by the purpose for which the material is being tested. 5 Washing procedure 5.1 Select the washing procedure to be used from those given in Table 1 if a front-loading type of machine is employed or from Table 2 if a top-loading type of machine is used. 5.2 Place the material to be washed in the washing machine (3.1) and add sufficient loading cloth (3.7) to make a total air-dry material load of the mass shown for the washing procedure selected. If dimensional stability is being determined, not more than half of the wash load shall consist of test specimens. Add sufficient detergent (3.3, 3.4 or 3.5, as appropriate) (1 to 3 g/l) to provide a good running suds having a height of not more than 3 cm at the end of the sudsing cycle. Water of hardness not exceeding 5 ppm (expressed as calcium carbonate) shall be used. If a front-loading horizontal drum type of machine is used, the detergent shall contain 4 parts of IEC detergent (3.5) to 1 part of sodium perborate tetrahydrate by mass. 5.3 After the last hydroextraction of the washing procedure has been completed, remove the material, taking care that it is neither stretched nor distorted, and dry it by one of the drying procedures described in clause 6. 3) Suitable machines are available commercially. Details may be obtained from the Secretariat of ISO/TC 38 or from the ISO Central Secretariat. Other machines can be used if it is determined they give equivalent results. 4) In cases of dispute, the interested parties should agree which type of machine should be used. If agreement cannot be reached, then Type A1 machine shall be used.

The warp or wale direction of the material should be vertical. Made-up articles should be suspended in the direction of use. 6.3 Procedure C — Dry flat Spread out the material on a horizontal screen drying rack (3.10), remove the wrinkles by hand without stretching or distorting, and allow it to dry. 6.4 Procedure D — Flat-bed press Place the material on the flat bed of the press (3.8). Smooth out heavy wrinkles by hand and lower the head of the press, which shall be set at a temperature suitable for the material to be pressed, for one or more short periods as required to dry the material. Record the temperature and pressure employed. 6.5 Procedure E — Tumble dry Place the material and the loading fabric in the tumble dryer (3.2) with the temperature of the exhaust from the drum set at a temperature not exceeding 70 °C for normal fabrics and 50 °C for permanent press or delicate fabrics. Operate the dryer until the load is dry, and continue tumbling for 5 min with the heat turned off. Remove the material immediately. 7 Test report The test report shall contain the following particulars: a) the type of machine and the washing and drying procedures used; b) the type of detergent used; c) total mass of the specimens and loading fabric; d) details of any deviation from the specified procedures.
