(Main)Household and similar electrical appliances - Safety - Particular requirements for commercial electric conveyor dishwashing machines
General Information
- Abstract
This clause of EN 60335-1 is replaced by the following. This European Standard deals with the safety of electrically operated conveyor dishwashing machines for washing plates, dishes, glassware, cutlery and similar articles (e.g. trays, food containers), with or without means for water heating or forced hot air drying, not intended for household use, their rated voltage being not more than 250 V for single-phase machines connected between one phase and neutral and 480 V for other machines. The spraying pressure shall not exceed 1 MPa. NOTE 101 These machines are used for example in restaurants, canteens, hospitals, and commercial enterprises such as bakeries, butcheries, etc. NOTE 102 Examples of such machines are – flight type dishwashers, – rack conveyor dishwashers. These machines are designed to be connected to hot and/or cold water supply. NOTE 103 Requirements to avoid backsiphonage of non-potable water into the public water supply are specified in Annex CC. Machines making use of steam or hot water for heating purposes are also within the scope of this standard. This standard does not apply to – machines which are moveable, – gas heating appliances which are part of conveyor dishwashing machines, – machines intended for disinfection, – machines intended to be used on board of sea-going vessels and aircraft, – machines designed exclusively for industrial purposes, for example machines used in the food industry for cleaning receptacles that serve as packaging for final products (e.g. bottle-cleaning machines), and machines used in manufacturing processes, – separately driven transport devices not confined in the machine, – machines intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).

Overview
EN 50416:2005 - Household and similar electrical appliances - Safety - Particular requirements for commercial electric conveyor dishwashing machines - is a European standard published by CLC that replaces the relevant clause of EN 60335-1. It defines safety requirements for electrically operated conveyor-type dishwashers used in commercial settings (restaurants, canteens, hospitals, bakeries, butcheries, etc.), covering machines designed to wash plates, dishes, glassware, cutlery and similar articles. The standard applies to machines with or without water heating or forced hot-air drying and limits the rated voltages and spraying pressures under which the equipment is covered.
Key Topics
- Scope and machine types
- Applies to conveyor (flight-type and rack conveyor) dishwashing machines intended for commercial use.
- Includes machines using steam or hot water for heating and machines designed to connect to hot and/or cold water supplies.
- Electrical and pressure limits
- Rated voltage limits: up to 250 V for single-phase (phase to neutral) and 480 V for other machines.
- Maximum spraying pressure: 1 MPa.
- Water safety
- Requirements to prevent backsiphonage of non-potable water into the public supply are specified (see Annex CC).
- Exclusions
- Not applicable to moveable machines, conveyor dishwashers with gas heating elements, machines intended for disinfection, machines for use on ships or aircraft, machines designed exclusively for industrial manufacturing (e.g., bottle-cleaning in packaging production), separately driven transport devices not confined in the machine, or machines for hazardous atmospheres.
- Safety topics (practical)
- Electrical safety, protection against mechanical hazards, thermal hazards from hot water/steam, and prevention of contamination through water connections.
Applications
Who uses EN 50416:2005:
- Manufacturers of commercial conveyor dishwashers for product development and conformity assessment.
- Test laboratories and certification bodies performing safety testing and CE marking assessments.
- Procurement and facility managers specifying compliant equipment for restaurants, commercial kitchens, hospitals, canteens, bakeries, and other food service enterprises.
- Compliance officers and safety engineers ensuring installations meet electrical, mechanical and water-supply safety requirements.
Practical benefits:
- Ensures safe operation under defined voltage and pressure limits.
- Minimizes risk of cross-contamination via water systems (backsiphonage protection).
- Provides a clear basis for regulatory compliance and market access in Europe.
