This part of GB/T 10067 specifies the requirements for experimental box type, tube type, and ground collapse resistance furnace products (hereinafter referred to as box type, tube type, and ground exhaust furnaces, collectively referred to as experimental resistance furnaces), including product classification, technical requirements, test methods, inspection rules and technical grading, marking, packaging, transportation and storage, as well as ordering and supply. This section is mainly applicable to resistance furnaces for natural atmosphere experiments, as well as box furnaces for protective atmosphere. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB 5959.1-2005 Safety of Electric Heating Equipment Part I: General Requirements GB/T 10066.1-2004 Test Methods for Electric Heating Equipment Part 1: General Part GB/T 10066.4-2004 Test Methods for Electric Heating Equipment Part 4: Indirect Resistance Furnace GB/T 10067,11-2005 Basic Technical Conditions for Electric Heating Equipment Part 1: General Part GB/T 10067.4-2005 Basic Technical Conditions for Electric Heating Equipment Part 4: Indirect Resistance Furnace GB/T 50065-2011 Connection of AC Electrical Equipment The terms and definitions defined in JB/T 9691-1999, GB/T10066.4-2004, and the following terms and definitions are applicable to this document. 3.1 Dimensions of furnace chamber The nominal dimensions of the furnace chamber. Note: For box furnaces, The "width" in the furnace size refers to the width of the furnace mouth, the "length" refers to the clearance distance between the inner side of the furnace mouth and the rear wall of the furnace, and the "height" Is the height of the furnace mouth, excluding the arched part of the upper part of the furnace mouth; For tubular furnaces, the length of the furnace is the axial size of the heating elements arranged inside the furnace, and the diameter is the inner diameter of the furnace tube; For a furnace, the height of the furnace is the axial size of the heating elements arranged inside the furnace, and the diameter is the inner diameter of the volute. 3.2 Protective Atmosphere The atmosphere used in a box furnace to protect the furnace material from oxidation and decarburization during heating. 3.3 Dimensions of Working Zone The dimensions of the working zone used in the experimental resistance furnace design are specified and indicated on the drawing, meeting the requirements for furnace temperature uniformity and allowing for the placement of furnace materials
