1 Scope

This part of GB/T 30839 specifies the general requirements for energy consumption classification of various types of electric heating baths, including energy consumption parameters and energy consumption of electric heating bath furnaces. Enclosure, energy consumption parameter classification and indicators, and test methods.

This part is applicable to electric heating bath furnaces used by industrial enterprises for heat treatment of metal parts in salt bath, alkali bath or oil bath. Similar electric baths, such as metal baths.

This part of the power supply hot bath furnace manufacturer, electric heating bath users in industrial production and related testing and arbitration institutions, assessment and evaluation of electric heating bath The energy consumption level of the furnace product and the energy consumption status during the actual use process to promote the improvement of the manufacturing level of the electric heating bath furnace to achieve energy saving and consumption reduction purpose.

This part can be used to develop a standard reference for energy consumption in the production process of electric heating bath furnaces.
