Colour Fastness Testing Gyrowash 815/20 Washing & Dry Cleaning Colour Fastness Tester Gyrowash 815/20 is an officially approved AATCC testing instrument for evaluating the colour fastness, staining potential and durability of fabrics under accelerated wash conditions, according to AATCC Test Method 61. Gyrowash 815/20 also complies with ISO 105 and conforms to the requirements of major European Retail Store Groups, including Marks and Spencer and Next. The instrument’s horizontal rotor can hold five test vessels
on each of the four sides thus having a maximum capacity of 20
large (1200ml) or 20 small (500ml) vessels, or a combination
of large and small. This makes it possible to use one machine
for both European and American standards.
