These Regulations shall apply to the dangerous devices with capacity as shown below: 1. Boilers (1) Steam boilers that have a maximum operating pressure exceeding one (1) kg/c㎡, or a heat transfer area exceeding one (1) ㎡ , which is either equipped with steam pipes open in the atmosphere with inside diameter above 25 mm, or equipped with the U-shape stand pipes with inside diameter above 25 mm , water head above 5 m, and heat transfer area over 3.5 ㎡ ), or that have inside diameter of shell body exceeding 300 mm or the body length exceeding 600 mm. (2) Hot water boiler that other than those heat medium boilers which have the water head above ten (10) m or heat transfer area above eight (8) ㎡ and the operating temperature exceeding the boiling point of the liquid under atmosphere pressure of one (1) ba. (3) Heat medium boilers with head pressure above 10m or transmission acreage above 8㎡. (4) Throughflow-type boilers that( including multi-pipe thoughflow boilers equipped with a cylinder header having inside diameter above 150 mm or equipped with a square header having sectional area above 177c㎡ ) have a maximum operating pressure above ten (10) km/c㎡ , or that (including those equipped with steam separators whose inside diameter over 300mm or those whose insidecapacity over 0.07m3 ) have the heat transfer area above ten (10) ㎡. 2. Pressure vessels: (1) Category Ι pressure vessels that have a maximum operating pressure above one (1) km/ c㎡ or internal volume over 0.2 m3. (2) Category Ι pressure vessels that have not only a maximum operating pressure above one ( 1) km/c㎡ but also an inside diameter above 500 mm and alength above 1000 mm. (3) Category Ι pressure vessels that have the product of the maximum pressure ( expressed in km/ c㎡) and the internalvolume (expressed in m3) exceeding 0.2. 3. Special equipment for highpressure gases: These special equipment refer to those equipment used for generation and related storage of the high pressure gages, as well as the supporting facilities ( including towers and tanks used for reaction, separation, refining or distillation purpose , where the distance between the highest tangent and lowest tangent of the towers are longer than five (5) m or the capacity of the storage tank is over 300 m3 or 3 tons), that the product of their design pressure ( expressed in km/ c㎡) and internal capacity (expressed in m3) exceeding 0.04. However, the vessels listed below shall be excluded from above category: (1) Vessels relating to pumps, compressors, pressure accumulators, etc. (2) Vessels relating to buffers and other relevant buffering instruments. (3) Vessels relating to flow meters, level gauges and other measuring instruments and filters. (4) Vessels used for the air conditioning equipment. (5) Vessels used for air compressing instruments having gauge pressure below 50 kg/c㎡ under the temperature of 35° C. (6) Vessels usedfor high-pressure vessels. (7) Other vessels designated by the central competent authority. 4. Vessels used for high-pressure gases: Except for those vessels listed below, these vessels refer to the vessels that used for containinghigh-pressure gases with the internal capacity over 500 liters, and that can be movablerelative to the ground: (1) Vessels not used in airtight conditions. (2) Vessels used for air compressing instruments having gauge pressure below50 kg/c㎡ under the temperature of 35° C. (3) Others vessels designated by the central competent authority.
