Begin with intended use
A countertop oven, a built-in domestic oven and a commercial forced-convection oven are not interchangeable certification categories. The correct route depends on portability, installation, voltage, intended users, location and whether the appliance is designed for household or commercial food processing.
Three important IEC examples
IEC 60335-2-9 covers portable cooking appliances for household and similar purposes. IEC 60335-2-6 covers stationary household cooking ranges, hobs and ovens. IEC 60335-2-42 covers commercial electric forced-convection ovens, steam cookers and steam-convection ovens used in professional food processing areas. Each part is used with the relevant general requirements.
Why scope changes the project
The applicable standard affects construction review, markings, instructions, abnormal-operation tests, temperature limits and the laboratory quotation. A late change from household to commercial intended use can require more than a label edit. Market-specific national deviations or standards may also apply.
Put intended use, installation and target countries in the first RFQ—not after the industrial design is frozen.
