Products that are classified as 'flame retardant' in accordance with the fire protection standard DIN 4102 valid in Germany are given the fire protection class 'B1'. The prerequisite for this classification is that the products do not continue to burn independently after the ignition source has been removed. Depending on the product and design, many of our articles have either temporary or permanent flammability. Our permanently flame-retardant products are provided with fire protection that cannot be washed out. In contrast, products whose B1 impregnation needs to be renewed after each wash are considered as temporarily flame retardant.
