The PERSPIROMETER is designed for use in the determination of colourfastness of textiles to water, seawater and perspiration.
STANDARDS BS 1006, BS EN 20105, ISO 105, AATCC 15, ISO 11642:2021 (E)
This tester can conform to but is not limited to the standards above.
The apparatus consists of a stainless steel frame with 21 acrylic separator plates and a load weight.
The PERSPIROMETER can be used in two configurations, depending on the test method being used (BS 1006, BS EN 20105, ISO 105
or AATCC 15). Each respective configuration applies the correct weight to the specimens.
Perspirometer is a piece of equipment used to determine the colour fastness of a textile to perspiration, water and sea water. Perspirometer consists of a frame, two pressure plates, 2 springs and 21 or 42 acrylic plates.
The total test weight applied to the sample will be 5kg for ISO standards and 10lb for AATCC standards. It must be noted the total test weight must be calculated by including the load weight and any relevant pressure plates and springs.
The test sample with multi-fibre or single adjacent fabric is fully immersed in the relevant test solution. Both test sample and multi-fibre or single fabric adjacent is are loaded between two acrylic plates* The plates are loaded into the frame being careful to have the pressure plates in the correct position. A load weight is applied to the top pressure plate and the frame locked to hold everything is place. The frame will be loaded into an incubator (temperature as per test specification) for a period of time. Once the test time is completed the test sample, multi-fibre or single fabric adjacent is dried and assessed for colour change and colour staining using the grey scale
*All acrylic plates must be loaded (for every test) into the frame irrespective of the number of test samples.
