适用范围：This recommendation applies to industrial furnaces heated indirectly with metallic heating elements (e.g., for heat-treatment, hot-forming, etc.) in which the internal atmosphere is composed of air not intentionally modified.This recommendation applies to batch chamber, bell, elevator, shaft, carriage, or to furnaces of any similar construction. These furnaces may be constructed either with or without forced air circu-lation.This recommendation covers furnaces of low and very low voltage categories (below 500 V).
