工厂在初建、改建、扩建时期,要自制一部分设备,以满足生产、试制或扩大再生产的需要,这部分设备统称为非标准设备。通常习惯上把自制的机床设备、试验设备(虽然它们也属于非标准设备范围),分别称为专用机床和试验设备;而把工厂铸、锻、热处理、表面处理用的槽子、炉子、烘箱、柜架、吊车以及工厂动力设施用的贮 During the initial construction, reconstruction, and expansion of the plant, a part of the equipment must be manufactured to meet the needs of production, trial production, or expansion of production. This part of the equipment is collectively referred to as non-standard equipment. It is customary to custom-make machine tool equipment and test equipment (although they also belong to the non-standard equipment range), namely special machine tools and test equipment; and to factory cast, forge, heat treatment, surface treatment tanks, stoves, ovens, Cabinets, cranes, and storage for factory power facilities
