This part of GB/T10067 specifies the general technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, ordering, and supply of various indirect resistance furnace products. This section is applicable to various experimental and industrial forced convection well resistance furnaces with rated temperatures ranging from 100 C to 950 C in natural and controlled atmospheres. Tempering, annealing, and normalizing of metal parts mainly used for heating and heat treatment, as well as carburizing, nitriding, carbonitriding, and blueing of steel parts. This section also applies to similar forced convection well type resistance furnaces, and different parts can be specified separately. This section does not apply to household and similar electric heating appliances. The following normative references are essential for the application of this document. For all dated references, only the dated version applies to this document. All undated reference documents. Their latest version (including all modification orders) Applicable to this document.
