9. Welding machines that fit for boiler product manufacture are required.
10. Examination Platform and tools, and hydrostatic pressure testing facilities suitable for production are also required.
11. Mechanical property testing facilities, physical and chemical property examination devices or a consignment relationship of the above mentioned testing and examination with competent subcontractors are required.
12. The applicants should have the machining tools, including cutting machines, presses and bevel machines for both plates and pipes to meet the demand for the manufacture of boilers of applied licensing level. Compact boiler manufacturer must have the ability to turn out final products.
Article 10
The resources requirements for the manufacture licensing of organic fluid heater and the resources requirements for level A boiler parts may consult the relevant resource requirements for the manufacture licensing of level C and level A boilers respectively. Furthermore, the manufacturing equipment required should match the manufacturing products.
