The PEGO’s GB21456 low-carbon steel standard pot fully meets four core dimensions of GB21456 -2024 “Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Household Induction Cookers”: material, size, appearance and performance. It is a typical representative of qualified standard steel pots. Its various indicators meet or even exceed the standard requirements.
I. Material of PEGO GB21456 Low Carbon Steel Pots
- PEGO’sGB21456 low carbon steel pot body and lid are made of Q235 low-carbon steel and the mass fraction of carbon is strictly controlled within 0.08%. It ensures that the electrical conductivity and magnetic permeability of the material meet the test requirements. It avoids unstable heat conduction efficiency caused by excessive material impurities and excessive carbon content. The surface of the PEGO GB21456 low-carbon steel pot is professionally sanded and rust-proof treated. It is smooth without burrs and scratches. It has no rust, deformation and other defects. The surface roughness fully meets the standard requirements. It not only ensures the heat conduction performance, but also improves the appearance integrity of the product.
- In the production process of the PEGO GB21456 low-carbon steel pot, the material undergoes multiple physical and chemical tests. It eliminates impurities, cracks, pores and other defects. The material uniformity is excellent. The material of pots can pass the calibration from third-party lab authorized by ISO17025.
II. Size of PEGO GB21456 Low Carbon Steel Pots
PEGO’s GB21456 low carbon steel vessels of different models (B1 ~ B4) are strictly met the size requirements of GB21456 (unit: mm). The deviation are all controlled within the range allowed by the standard:
- Model B1: caliber 140, bottom diameter 120, pot height 75, pot thickness 1.5, capacity 1L;
- Model B2: caliber 200, bottom diameter 180, pot height 95, pot thickness 1.5, capacity 3L;
- Model B3: caliber 220, bottom diameter 200, pot height 110, pot thickness 1.5, capacity 4L;
- Model B4: caliber 280, bottom diameter 260, pot height 105, pot thickness 2.0, capacity 6L;
- The thickness of the lid is uniformly 1mm, and ithasa through hole with a diameter of 10mm. The size deviation does not exceed ±0.5mm. The maximum concavity of the pot bottom does not exceed 0.6% of the effective diameter. It is not allowed to bulge outward. The sizes of each model of the PEGO GB21456 low-carbon steel pot are accurately matched with the above requirements. The size deviation is strictly controlled within ±0.5mm. All lids have a through hole with a diameter of 10mm. The concavity of the pot bottom meets the standard. the lid size also strictly corresponds to each model of pot body (such as model B1 lid caliber 146mm, thickness 1.0mm).
III. Appearance of PEGO GB21456 Low Carbon Steel Pots
- The surface of the PEGO GB21456 low-carbon steel pot is professionally sanded and rust-proof treated. It is smooth without burrs and scratches. It has no rust, deformation and other defects. The surface roughness fully meets the standard requirements. It not only ensures the heat conduction performance, but also improves the appearance integrity of the product.
- The connection between the pot body and lid of the PEGO GB21456 low-carbon steel pot is flat and firm. It has no looseness or gaps. It effectively avoids heat loss.
(IV) Performance of PEGO GB21456 Low Carbon Steel Pots
- The PEGO GB21456 low-carbon steel pot conducts heat uniformly. It has no local overheating or heat conduction lag. Heat transfer is fast and uniform. It fully meets the conduction requirements of thermal efficiency testing. It ensures the accuracy of test data.
- Under rated power heating conditions, the PEGO GB21456 low-carbon steel pot has no obvious deformation or damage. The surface temperature distribution is uniform. The material performance is stable. It can meet the needs of repeated tests. The consistency is excellent.
- The bottom design of the PEGO GB21456 low-carbon steel pot fits the induction cooker panel. It is suitable for induction cooker heating units of different power levels from 700W to 3500W. During heating, there is no shaking or sliding. The electromagnetic induction is stable. It effectively reduces heat loss.
In summary, the PEGO GB21456 low-carbon steel standard pot achieves full compliance with the GB21456-2024 standard in all four core dimensions of material, size, appearance, and performance. From the strict control of raw material quality and multiple professional tests to the precise control of size deviations, the exquisite surface treatment, and the stable and efficient performance in practical use, every detail reflects PEGO’s pursuit of quality and compliance. As a typical representative of qualified standard steel pots, it not only meets the basic requirements of household induction cooker energy efficiency testing, but also exceeds the standard in many indicators, providing reliable, stable and high-quality supporting equipment for relevant testing work and household use. With its excellent material uniformity, precise size matching, perfect appearance and outstanding performance, it has become a trustworthy choice in the field of low-carbon steel standard pots.
