Vishay Telefunken Ozone Depleting Substances Policy Statement
policy Vishay Semiconductor GmbH Meet present future national international statutory requirements. Regularly continuously improve performance products, processes, distribution operating systems with respect their impact health safety employees public, well their impact environment. particular concern control eliminate releases those substances into atmosphere which known ozone depleting substances ODSs Montreal Protocol 1987 London Amendments 1990 intend severely restrict ODSs forbid their within next years. Various national international initiatives pressing earlier these substances. Vishay Semiconductor GmbH been able policy continuous improvements eliminate ODSs listed following documents. Annex list transitional substances Montreal Protocol London Amendments respectively Class ozone depleting substances Clean Amendments 1990 Environmental Protection Agency Council Decision 88/540/EEC 91/690/EEC Annex transitional substances respectively. Vishay Semiconductor GmbH certify that semiconductors manufactured with ozone depleting substances contain such substances.
reserve right make changes improve technical design without further notice. Parameters vary different applications. operating parameters must validated each customer application customer. Should buyer Vishay-Telefunken products unintended unauthorized application, buyer shall indemnify Vishay-Telefunken against claims, costs, damages, expenses, arising directly indirectly, claim personal damage, injury death associated with such unintended unauthorized use.
