Standards Development

Scope

This clause of Part 1 is replaced with the following.

This document deals with the safety of electrically operated commercial conveyor dishwashing machines for washing dishes, glassware, cutlery and similar reusable articles, with or without means for water heating or drying, not intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances.

These conveyor dishwashing machines are designed to be connected to hot and/or cold water supply. Dishwashing machines making use of steam or hot water for heating purposes are also within the scope of this document.

These appliances are used by experts or instructed persons for commercial dishwashing in areas not open to the public, for example in kitchens of restaurants, canteens, hospitals, and in commercial enterprises such as bakeries and butcheries.

NOTE 101 Examples of such appliances are:

— flight conveyor dishwashing machine;

— rack conveyor dishwashing machine.

Requirements to avoid backsiphonage of non-potable water into the water mains are specified in Annex BB.

This document deals with specific requirements on noise emitted from these appliances because the generated noise can be LpA > 70 dB(A) and is considered to be a relevant hazard. See Clause 7.12.104, 22.115 and Annex CC.

The electrical part of appliances making use of other forms of energy is also within the scope of this document.

This document deals with the reasonably foreseeable hazards presented by appliances that are encountered by all persons in and around the installation place or workplace.

NOTE 102 Attention is drawn to the fact that:

— for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;

— in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities;

— in many countries, additional requirements are specified for appliances incorporating pressurized parts;

— for scrapping of appliances, additional requirements can be necessary.

This document does not apply to:

— commercial electric dishwashing machines under EN IEC 60335‑2‑58;

— appliances 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;

— gas heated appliances which are part of the conveyor dishwashing machines;

— movable appliances;

— dishwashing machines that do not form one functional unit, for example where a transportation device transfers the load from one separate unit to another;

— separately driven transport devices not confined in the appliance;

— appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);

— sterilizers and washer-disinfectors used to treat medical materials (EN IEC 61010‑2‑040).With this European revision 2.0 of the document, the EN 50416:2005 [1]is superseded.

This European revision 2.0 of the document, supplements or modifies the corresponding clauses of the standards below:

— EN IEC 60335‑1:2023+A11:2023+prA12:2026.

Secretary’s note: The above addition has been moved from the Introduction (informative text) to the Scope (normative text) of the standard following discussions with the HAS consultants. According to an EC decision (document GROW.H.3/SM/MH/DT 12/1/2024), Part 1 must be referenced by date in Part 2. Consequently, the standard has been included in Clause 2, “Normative references”.

This document contains requirements for appliances with radio function, remote communication, and remote operation.

For the scope of this document, the term radio appliance is used with the same meaning of radio equipment.

For the scope of this document, the term appliance is used with the same meaning of equipment.

Secretary’s note: the above sentence has been modified in base of the RED HAS comment. The same sentence are included also in Clause 3 “Term and Definitions”

Compliance with this Part 2 when used together with the Part 1 provides one means of conformity with the safety objectives as listed in Table ZZB.1
