The RoHS Directive (Restriction of certain Hazardous Substances) of the European Union (EU) regulates the restriction of hazardous substances. It prohibits the use of certain substances in electrical and electronic equipment after July 2006. It concerns the ban on the use of lead, mercury, cadmium, hexavalent chromium and brominated flame retardants and polybrominated diphenyl ethers in electrical and electronic equipment placed on the market. SR SYSTEM-ELEKTRONIK produces built-in monitors and industrial computers in the EU, therefore these guidelines are authoritative for SR SYSTEM-ELEKTRONIK: According to article 2 paragraph 1, the equipment category that SR produces is excluded. Quote: "Without prejudice to Article 6, this Directive shall apply to electrical and electronic equipment falling within categories 1,2,3,4,5,6,7 and 10 listed in Annex IA to Directive 2002/95/EC or 2011/65/EU and 2015/863 (on waste electrical and electronic equipment) respectively, and to electric filament lamps and luminaires in households. " Category 9 "Monitoring and control instruments", which includes among others "other monitoring and control instruments of industrial installations (e.g. in control panels)", is expressly excluded from the RoHS Regulation, i.e. not applicable to SR SYSTEM-ELEKTRONIK.SR SYSTEM-ELEKTRONIK will, however, deliver RoHS compliant as far as possible from July 1st, 2006. This is not feasible for CRT monitors anyway, because the tube contains lead for shielding. According to the appendix of the Directive, there is an exception for CRTs and electronic components as well as fluorescent tubes, so these devices may continue to be supplied. Furthermore, all mechanical parts of the housings are already manufactured according to the valid guidelines.
