![]() ![]() ![]() Sulfur-Hexafluoride (SF 6) is a isolating and switching gas widely used in medium and high voltage switchgear. In addition there exist companywide environmental regulations by larger manufacturing groups i.e. A leading role in these efforts has been played by the automotive industry which is shown in the declaration and restriction list of the german association of automotive manufacturers (VDA 232-101), which then expanded into the „Global Automotive Declarable Substance List“ (GADSL) listing. This will be mainly dependent on which substances may be added to the SVHC (Substances of Very High Concern) list.Ĭontractual agreements between manufacturers and users, often on the basis of product specifications, can further ban or limit the use, or make it subject to declarations of hazardous materials also in electrical contacts. So far REACH has no implications on electrical contacts but it probably will in the foreseeable future. Since 2007 the EU has worked on and issued a new version of the chemical substance law through the REACH regulation (Registration, Evaluation, Authorization and Restriction of Chemicals). For the other areas mentioned the TA Air is of importance. For the first one please see the German MAK and BAT Value List. These regard the areas of work place effects and emissions in exhaust air, waste water, and through scrap disposal. Pb contents of 80-85 wt% ́Cd in electrical contactsĪdditional regulations for the manufacturing and further use of contact materials have to be observed. Pb in Cu materials, Steel, AI up to defined limit values Pb in high melting solders with Pb in Cu materials, Steel, Al up to defined limit values Pb in solders forĮlectronic components: exemption valid throughĮlectrical and electronic devices for consumer market (Details see Exh. Passenger cars and trucks up to 3.7 t GWV and spare parts for these EU end of life vehicle regulation (ELV).RoHS and WEEE are covered in Germany by the „ElectroG“ law. The EU regulation on electrical and electronic scrap (WEEE ) does not contain limitations on hazardous materials and is not discussed in detail here. Regarding electrical contacts the “End of Live (for) Vehicles (ELV) and the electrical devices regulation "Restrictions on the Use of Hazardous Substances in Electrical and Electronic Equipment" (RoHS), have to be mentioned. Because of ongoing changes and to obtain details on the included substances, their maximum allowable contents, and certain exemptions, it is highly recommended to look up the most current status of EU legislation and related discussion points at In addition to substance related regulatory restrictions, the EU issues also directives for use restrictions or bans for certain application ranges. In Germany these are included in the "Law on Chemical Substances" and the "Hazardous Materials Regulation". Since 1968 restrictions for the use and application of substances determined to be hazardous to the human health have been regulated uniformly throughout the countries of the European Union. Use Restrictions in the European Union (EU) Legal Regulations and Restrictions 3 Hazardous Substances in Electrical Contacts.1.2 Use Restrictions Based on Agreements.1 Use Restrictions in the European Union (EU).In this chapter we show also references directly in the text to aid the reader in looking up more detailed resources regarding specific subjects of this rather complex and constantly changing issue.īecause of the ongoing changes on this subject it is important to note that the following data are only for general orientation, do not claim to be in anyway complete, and do not claim to be legally correct. They are meant as general guidance to the engineering community in the field of electrical contacts and meant to provide a starting point and listing of resources during the design process that requires the selection of electrical contact materials and components. Regarding the subject of electrical contacts the following chapter provides a review of current government regulations and voluntary restrictions implemented by the industry as of the beginning of 2010 for mainly the European Union, but also some data and resources for North America and Asia (mainly China).The data shown and information given concern the manufacturing and use of electrical contacts and related materials and technologies. Have led to and continue to impact discussions about restrictions of certain substances. Increasing research data and awareness about the problems surrounding environmentally sensitive and health effecting substances in industrial goods
