DIN 402 is the law that specifies the fire-retardant effect of materials, drawn up by the German Institute for Standards. They are also responsible for the well-known DIN 474 standard, which determines the common paper formats. DIN 4102 is comparable to the European standard EN 13501-1

Standards such as DIN 4102 and EN 13501-1 are crucial for the construction industry, as they help ensure the safety of buildings and their occupants by setting strict requirements on the fire reaction of materials used. This includes testing materials for flammability, flame spread, smoke development, and the release of flaming droplets or particles. Adhering to these standards is essential for manufacturers, architects, and construction companies to comply with regulatory requirements and ensure the safety and quality of their projects.
