The term asbestos stands for a group of very resistant and non-flammable minerals with a fibrous structure. Until the beginning of the 1990s they were mainly used for thermal insulation or fire protection. Asbestos is found in brake pads and clutches, in electrical appliances, in machines and technical equipment, in heating systems and, above all, as a building material in a great many buildings. Asbestos fibres that enter the lungs can cause asbestosis, hardening and scarring of connective tissue, and cause cancer. In the meantime it has also been proven that asbestos substitutes, such as artificial mineral fibres, KMF, can cause cancer.

We offer you the classification of 'old mineral wool' or such mineral fibres without RAL quality mark regarding their carcinogenic risk potential The carcinogenicity index, KI, is a dimensionless quantity and is determined according to the material composition of the mineral fibres to be evaluated. According to IFA / BIA method 7488, it is calculated from the sum of the mass contents (in MA-%) of Na2O, K2O, CaO, MgO, BaO and B2O3 minus twice the mass content of Al2O3. Vitreous mineral fibres are classified according to the KI according to TRGS 905 as follows, if their dimensions correspond to the WHO - fibre - definition: (length > 5µm, diameter < 3 µm, ratio length : diameter > 3 : 1) Glassy WHO fibres with a carcinogenicity index KI <= 30 are classified in category 1B. WHO vitreous fibres with a carcinogenicity index KI > 30 and KI < 40 are classified in category 2. WHO vitreous fibres shall not be classified as carcinogenic if their carcinogenicity index KI >= 40.
