If a textile item has been awarded the STANDARD 100 label, consumers can be sure that all components of this item, i.e. all threads, buttons and other accessories, have been tested for harmful substances and the item is therefore human-ecologically harmless. Tests are carried out for harmful substances that are prohibited or regulated by law and for chemicals that are harmful to health and for which there are still no legal specifications for textiles. The pH value of the material and the colour fastness are also tested.
