Prepare the Specimen
A 40 × 100 mm specimen is sewn to a multifibre strip along one short edge.

TESTMETOD · ISO 105-E01
Färghärdighet mot vatten ISO 105-E01
ISO 105-E01 visar om ett tyg fäller färg när det är vått. Testet använder samma utrustning som svetttestet, men med vatten i stället för svett. Den amerikanska motsvarigheten är AATCC 107.
Provbitar uttagna ur bulkpartiet.

What This Test Measures
The fabric and a multifibre strip are soaked in distilled water, held under pressure at body temperature, dried and graded. Poor results show up as bleeding onto light fabrics in a wet garment or damp storage.
02
How We Run It in Our Lab
Our technicians follow a written work instruction for this method.
Water and perspiration tests share equipment and are often run together.
Soak
The composite is fully wetted in distilled water for 30 minutes, then excess water is removed.
Hold Under Pressure
Specimens are held between resin plates under 12.5 kPa at 37 ± 2 °C for 4 hours.
Dry and Grade
Dried at no more than 60 °C. 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.

Writing This Test into Your Specification
Pair It with Wet Rubbing
Water fastness and wet rubbing describe related risks; specify both for dark shades.
Separate Change and Staining
Give one grade for colour change and one for staining.
Name the Method
ISO 105-E01, AATCC 107 and GB/T 5713 are similar but not identical.

Questions About ISO 105-E01
What does colour fastness to water show?
Whether a fabric bleeds colour when wet, which predicts staining when wet garments touch light fabrics.
Is ISO 105-E01 the same as AATCC 107?
They test the same property in a similar way, but details differ, so the method should be named in the specification.
Which shades need the most attention?
Dark and bright shades, especially on cotton.
