Check whether the audit covers the actual manufacturing address;
verify calibration certificates; confirm that test conditions match
the final rated voltage, frequency, and power; and review change-control procedures.
|
| Regional electrical-appliance distributor |
Standard catalog models intended for domestic kitchens, student housing,
temporary cooking areas, small offices, and hospitality use.
|
Usually supplied in the electrical configuration required by the local market;
plug and labeling should match the destination country before shipment.

|
| Specialty small-appliance supplier |
Higher-duty portable heat plates for catering, buffet service,
demonstration kitchens, mobile food service, and frequent-use environments.
