This document specifies the requirements for classification of heat treatment furnaces according to temperature uniformity, initial test and periodic test of qualified work zones, test systems, test methods, result evaluation, records and reports, and management. This document is suitable for determining the qualified work zone of a heat treatment furnace that meets temperature uniformity requirements within the operating temperature range. This document does not apply to work zones in continuous heating furnaces where there is no fixed process-specified heating temperature or where temperature uniformity is not required. This document can be used as a reference for other heating equipment.
