The CE Marketing Directive (93/68/EEC) for the LVD came into force on January 1, 1995, subject to a two-year transition period. All heaters operating on a supply voltage of between 50 and 1000VAC and between 75 and 1500VDC fall within the scope of the LVD. The Self Declaration of Conformity shown on the right, backed by our risk assessment and technical file, assure that the product series shown on the Declaration meet the EU requirements. The declaration is not applicable to any of our heaters intended for use in an explosive atmosphere, or for radiological and medical purposes. For heaters intended for use in an explosive environment, see the  ATEX section  of page 568.
