Test vessels, also call as standard cooking vessels and induction hob vessels. It is a tool to simulate the cooking appliance. The standard cooking vessels apply to perform the normal operation test, for testing induction hob elements, induction hotplates and induction cooking appliance under the standards IEC60335-2-6:2014 clause 3.1.9.101, IEC60335-2-9:2019 clause 3.1.9.105 and CISPR14-1:2016.
2. The materials and dimension of standard cooking vessel
2.1 Material
The vessels are made of low carbon steel having a maximum carbon content of 0.08%. However, according to authoritative testing, the carbon content of the steel used by PEGO is ≤ 0.06%.
2.2 Dimension
Regularly, the standard cooking vessel has a circular shape (φ110mm, φ145mm, φ180mm, φ220mm/φ210mm, φ300mm), but non-circular vessels can be customized for testing non-circular cooking zones.
The vessel is cylindrical without metallic handles or protrusions. And the diameter of the flat area of the base is to be at least the diameter of the cooking zone. The maximum concavity of the base of the vessel is 0.06d, and the base of of the vessel is not to be convex. The surface is sprayed with high temperature non-stick coating.
For testing the induction hotplates and induction cooking appliance (as per IEC60335-2-9:2019 and CISPR14-1:2016), base and wall thickness is 2mm±0.5mm. However, for testing the induction hob elements (as per IEC60335-2-6:2014), the wall thickness of the vessel also is 2mm±0.5mm, but there is different requirement for the base thickness.
3. How to operate the test?
The low carbon steel vessel that contain cooking oil is placed on Induction hob elements. The diameter of the bottom of the vessel is approximately equal to the diameter of the cooking zone. Position The vessel centrally on the cooking zone. Adjust thermal controls to their highest setting until the oil temperature reaches 180℃±4℃, and then adjusted so that this temperature is maintained. The oil temperature is measured 10mm above the centre of the bottom of the vessel.
4. Why Pego?
In actual production, different manufacturers have different production processes for the connection between the base and the wall of the vessels. Normally, the walls are welded together with the base, this process saves materials and reduces production costs, but it is not durable and will leak after long-term use.
However, PEGO adopts one-piece molding technology to produce the vessel, the base and wall of the vessel are made of one piece of material, without any gaps. The cost is higher, but it is more duration.
5. How to protect the standard cooking vessels?
- After each use, please use clean cloth to wipe it clean.
- Do not dry burn the vessel, or the coating of the vessel will destroy. And the vessel will rust easily without the protection coating.
- Do not damage the appliance shape and coating (such as scratching, dropping, etc.).
- Prevented from dust and moisture environment, in order to avoid the rusts.
