European foreword
This document (EN 50416:2005/A1:2015) has been prepared by CLC/TC 61 "Safety of household and similar
electrical appliances".
The following dates are fixed:
– latest date by which this document has to be implemented at (dop) 2016-08-10
national level by publication of an identical national standard
or by endorsement
– latest date by which the national standards conflicting with (dow) 2018-08-10
this document have to be withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights.

This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
For the relationship with EU Directive 2006/42/EC, see informative Annex ZZ, which is an integral part of this
document.
NOTE 1 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in
a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 2 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated noun are also
in bold.
1 Modification to Foreword
Replace the first paragraph after the application dates by the following:
This European Standard applies in conjunction with EN 60335-1:2012 and its amendments, which is referred
to in this document as “Part 1”. This European Standard supplements or modifies the corresponding clauses
of Part 1 as indicated in the text.
2 Modification to Introduction
Replace the text of the Introduction by the following:
This European Standard has been prepared to provide a means of conforming to essential safety
requirements of the Machinery Directive 2006/42/EC. Other requirements and other EU Directives may be
applicable to the machines falling within the scope of this European Standard.
This European Standard is a product family standard dealing with the safety of commercial electric conveyor
dishwashing machines and takes precedence over horizontal and generic standards covering the same
subject.
This European Standard recognizes the level of protection against hazards such as electrical, mechanical,
thermal, fire and radiation of commercial electric conveyor dishwashing machines when operated as in
normal use taking into account the manufacturer's instructions. It also covers any reasonably foreseeable
misuse of the machinery and takes into account the way in which electromagnetic phenomena can affect the
safe operation of commercial electric dishwashing machines.
A commercial electric conveyor dishwashing machine that complies with the text of this European Standard
will not necessarily be considered to comply with the safety principles of the standard if, when examined and
tested, it is found to have other features that impair the level of safety covered by these requirements.
This European Standard takes into account the requirements of HD 60364-1 as far as possible so that there is
compatibility with the wiring rules when the machinery is connected to the supply mains. However, national
wiring rules may differ.
Pressurized components incorporated in machines within the scope of this European Standard are pressure
equipment that is classified no higher than category I of the Pressure Equipment Directive (93/68/EU).
According to Article 1, item 3.6 of the Pressure Equipment Directive, this equipment is excluded from its
scope.
The requirements of Annex CC of this European Standard do not support a relevant ESHR of the Machinery
Directive 2006/42/EC.

5 Modification to Clause 3 Definitions
3.1.9 Replacement:
normal operation
appliances intended to be connected to a water supply are connected to a water supply having the pressure
and temperature specified in the instructions.
If a range of temperatures and pressures is specified in the instructions then the water supply is at the
conditions within the range that will give the most unfavourable temperature results.
Water inlets intended for cold water only are connected to a source supplying water at a temperature of
15 °C ± 5 °C.
The appliance is filled with the maximum quantity of water for which it is designed, without detergents or
rinsing agents. The appliances are tested without dishes.
The appliances are operated continuously.
For normal operation conditions, the appliance is operated as follows:
– appliances are operated in accordance with the instructions for use, but with the controls intended to be
set by the user set at maximum or that setting giving the most unfavourable temperature results.
Add the following:
3.105
guard
part of the appliance specially designed to provide protection by means of a physical barrier
3.106
operator
