適用范圍：This part of IEC 60519 is applicable to indirect resistance heating equipment for the heatingand melting of glass, operating in voltage bands 1 and 2. These particular requirements alsoapply to equipment for direct resistance heating and melting of glass by means of currentintroduced by electrodes passing through the charge to be heated.The object of this standard is the determination of safety requirements for both indirect anddirect resistance heating equipment for the heating and melting of glass.NOTE Extraction of liquid glass or a similar material at the extraction point is part of the production process anddoes not constitute part of the operation of the electroheat equipment.This standard covers the safety aspects of electrical parts also in the case when electricalheating is combined with other means of heating, for example liquid fuel heating.These requirements do not apply to equipment for direct resistance heating, where, owing tothe technology used, IEC 60519-3, IEC 60519-4 and IEC 60519-8 are applicable.
