用途：用于日曬和氣候色牢度測試

Blue Wools are used for light and weathering fastness testing. We supply 'European' Blue Wool Standards （ISO 105-B08）, which originate from DEK （Deutsche Echtheitskommission）. DEK hold the global master standard for Blue Wools and every batch produced is checked for compliance against the master before it is released. In cases of need, the comparative test results will be made available.
