Standard Cooking Vessels for Induction Elements Tests: Key Insights under IEC60335 - 2 - 6 & IEC60335 - 2 - 9

1. Fundamental Role of Standard Cooking Vessels

Standard cooking vessels, also known as induction elements test vessels, are of utmost importance in mimicking real - world cooking appliance scenarios. Their core function is to enable normal operation tests for induction hob elements, induction hotplates, and induction - based cooking appliances. These vessels are precisely engineered to meet the strict test requirements laid out by IEC60335 - 2 - 6:2014 clause 3.1.9.101, IEC60335 - 2 - 9:2019 clause 3.1.9.105 and CISPR14-1:2016.


2. Constituent Materials and Exact Dimensions of Standard Cooking Vessels

2.1 Material Composition

Constructed from low - carbon steel, these induction elements test vessels have a predefined maximum carbon content of 0.08%. Notably, through reliable and authoritative testing, the steel used by PEGO, a prominent entity in this field, has an even lower carbon content, capping at ≤ 0.06%. This reduction in carbon content endows enhanced material properties, contributing significantly to the overall quality of the standard cooking vessels.

2.2 Dimensional Specifications

Predominantly, standard cooking vessels adopt a circular configuration, with diameters ranging from φ110mm, φ145mm, φ180mm, φ220mm/φ210mm, to φ300mm. However, in cases where non - circular cooking zones need to be evaluated, bespoke non - circular standard cooking vessels can be fabricated.
The vessel's design is cylindrical, deliberately free from any metallic handles or protruding elements. The diameter of the flat base area must be at least equivalent to the diameter of the cooking zone it is intended for. The base of the standard cooking vessel has a maximum allowable concavity of 0.06d, while convexity is strictly prohibited. To enhance its usability and longevity, the surface is adorned with a high - performance, high - temperature - resistant non - stick coating.
When it comes to testing induction hotplates and induction cooking appliances in line with IEC60335 - 2 - 9:2019, the base and wall thickness of the induction elements test vessels are uniformly set at 2mm±0.5mm. Conversely, when the focus is on testing induction hob elements as per IEC60335 - 2 - 6:2014, although the wall thickness remains constant at 2mm±0.5mm, the base thickness requirements vary. For vessels with a diameter ≤ φ145mm, the base thickness is 2mm±0.5mm; for those with a diameter >φ145mm and ≤φ240mm, it increases to 3mm±0.5mm; and for vessels larger than φ240mm, the base thickness is set at 5mm±0.5mm.


3. Operational Protocols for Testing with Induction Elements Test Vessels

Initiating the test procedure involves carefully placing a low - carbon steel induction elements test vessel filled with cooking oil onto the induction hob elements, induction hotplates, or induction cooking appliance. It is crucial that the diameter of the vessel's bottom closely approximates that of the cooking zone, and the vessel is accurately centered over the cooking zone. Initially, the thermal controls are ramped up to their maximum settings until the oil temperature reaches a precise 180℃±4℃. After that, the controls are meticulously adjusted to ensure the sustained maintenance of this temperature. The oil temperature is measured precisely 10mm above the center of the vessel's bottom.


4. The PEGO Advantage in Manufacturing Standard Cooking Vessels

In the manufacturing domain, different producers employ diverse production techniques for fusing the base and wall of these standard cooking vessels. A common approach involves welding the walls to the base. While this method is cost - effective in terms of material utilization and production expenses, it often falls short in terms of long - term durability and is prone to leakage issues over extended usage periods.

PEGO, in contrast, has adopted a revolutionary one - piece molding technique. With this method, the base and wall of the induction elements test vessels are seamlessly formed from a single piece of material, completely eliminating any potential gaps. Although this approach incurs higher production costs, the resulting standard cooking vessels exhibit remarkable durability, making them a preferred choice for discerning users.  Welcome to access our website: www.pegotesters.com, www.pegotester.com
