Prepare the Specimen
A 40 × 100 mm specimen is sewn along one short edge to a multifibre strip of the same size, with white polyester thread.

Kleurvastheid voor wassen ISO 105-C06
ISO 105-C06 meet kleurverandering en afgeven in een versnelde huishoudelijke of commerciële was. Onze gebreide stoffen meten cijfer 4 tot 4-5 voor kleurverandering. Het Amerikaanse equivalent is AATCC 61.

What This Test Measures
A fabric specimen is sewn to a multifibre strip of six fibres and washed in a closed steel container with detergent solution and steel balls, then rinsed and dried. Technicians grade the colour change of the specimen and the staining of each fibre.
The procedure code sets the severity: the letter sets the temperature (A = 40 °C, B = 50 °C, C = 60 °C and higher), the figure sets the solution, for example whether sodium perborate is added, and S or M stands for a single or multiple-wash simulation. A1S is the mildest common procedure; A2S adds perborate at the same temperature.

How We Run It in Our Lab
Our technicians follow a written work instruction for this method.
Each specimen is washed under the procedure code agreed for the order.
Wash
The composite goes into a 550 ml steel container with 150 ml of solution and 10 steel balls (A1S: 4 g/L ECE reference detergent), at 40 ± 2 °C and 40 ± 2 rpm for 30 minutes.
Rinse and Dry
The specimen is rinsed, squeezed and dried at no more than 60 °C.
Grade
Graded with the ISO 105-A02 grey scale for colour change and A03 for staining (AATCC EP1/EP2 for AATCC methods), under the agreed light source in a light booth, by at least two technicians.

Measured Range and Buyer Values
Results depend on fibre, construction, shade and finishing.
| Fabric / shade | Ons gemeten bereik | Values in buyer specifications |
|---|---|---|
| All our knit fabrics, colour change | Grade 4 to 4-5 | Grade 4-5 |
| SGS example (chenille knit, A2S) | Change 4-5; staining 4 to 4-5 | — |
“Our measured range” comes from our own test records on bulk lots. “Values in buyer specifications” are requirements we have received; the value that applies to your order is the one written into it. — Xiwen Zhang, Co-founder & CEO

Writing This Test into Your Specification
Name the Procedure
Write the full code, for example ISO 105-C06 A2S or AATCC 61 2A. “Washing fastness 40 °C” does not say whether bleach is used or how many washes are simulated.
Set Change and Staining Separately
Give one grade for colour change and one for staining.
Group Shades
State whether one value applies to all shades or whether dark shades have their own staining value.

Questions About ISO 105-C06
What does A2S mean in ISO 105-C06?
A2S is a single-wash procedure at 40 °C with 4 g/L ECE detergent and 1 g/L sodium perborate, 150 ml of solution and 10 steel balls for 30 minutes. A1S is the same without perborate.
What washing fastness do your fabrics reach?
Our knit fabrics measure grade 4 to 4-5 for colour change in ISO 105-C06. We confirm the expected staining result for your shade before the order.
Is ISO 105-C06 the same as AATCC 61?
No. Both are accelerated laundering tests in similar equipment, but detergent, temperature, liquor volume and number of steel balls differ, so results are not interchangeable.
