This document is applicable to the production, sales, and inspection of cast iron pots. Main technical contents: 1. The wall of the pot should be thin at the top and thick at the bottom, with uniform thickness at the symmetrical parts, and the error shall not exceed 1/3 of the average thickness. 2. The tolerance requirements for the diameter of cast iron pots are: (1-0.5%)D ~ (1+0.5%)D; the tolerance requirements for depth are: (1-1%)H ~ (1+1%)H. 3. The flatness error of the pot edge shall not exceed 0.5% of the diameter of the pot. 4. Heat the cast iron pot to 324℃~400℃ and then shock it with cold water. There shall be no cracking. 5. The cast iron pot should not leak when holding water. 6. After the cast iron pot is filled with water, there shall be no cracking or obvious deformation in the handle assembly and riveted parts, and the handle bracket shall not be loose. 7. The tensile strength of the cast iron pot shall not be less than 150 MPa. 8. The coating performance shall comply with the provisions of GB 4806.10, section 4.2.
