What cookware requirements apply to commercial induction cookers?

Please verify the following points and require itemized written supplier responses:（commercial induction cooker induction-cookware） Cookware must be magnetic, with a flat, evenly thick base matching the heating zone. Non-magnetic aluminum, glass, ceramic or stainless steel usually will not work. Heavy or deformed cookware affects heating and stresses the panel, so confirm it with the cooker. Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
