- heated tops;
- heated display cases;
- heated crockery dispensers;

These appliances are not intended for household and similar purposes. They are used for commercial purposes, processing of food, also in areas open to the public, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises, such as bakeries and butcheries.
The electrical part of appliances making use of other forms of energy is also within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by these types of appliances.
