It
16、 covers safety aspects which are related to conveyor dishwashing machines. A first draft was submitted to the Unique Acceptance Procedure in July 2003. Due to a negative advice from the MD Consultant, received during the ongoing UAP, CENELEC TC 61 agreed in its meeting in Athens in November 2003 to
17、review the draft. An ad-hoc meeting between the MD consultant and the WG responsible for EN 50416 in March 2004 resolved all concerns of the MD Consultant. A second draft was submitted to the formal vote and was approved by CENELEC as EN 50416 on 2004-12-07. The following dates were fixed: latest da

19、 60335-1, Household and similar electrical appliances Safety Part 1: General requirements, which is referred to as Part 1. It was established on the basis of the 2002 edition of that standard. Amendments and revisions of Part 1 have also to be taken into account and the dates when such changes becom
20、e applicable will be stated in the relevant amendment or revision of Part 1. This standard, supplements or modifies the corresponding clauses of Part 1, so as to convert it into the European Standard: Safety requirements for commercial electric conveyor dishwashing machines. When a particular subcla
21、use of Part 1 is not mentioned in this standard, that subclause applies as far as is reasonable. When this standard states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. This European Standard has been prepared under a mandate given to CENELEC
22、by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 98/37/EEC. See Annex ZZ. 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; - unles

Othe
32、r requirements and other EU Directives may be applicable to the machines falling within the scope of this standard. Pressurized components incorporated in machines within the scope of this standard are pressure equipment which is classified no higher than category I of the Pressure Equipment Directi
33、ve. 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 standard do not support a relevant ER of the Machinery Directive 98/37/EC. Licensed Copy: Wang Bin, na, Wed May 25 07:40:56 BST 2005, Uncontrolled
34、Copy, (c) BSIEN 50416:2005 - 6 - 1 Scope 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
35、 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 mac
36、hines 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 1
37、03 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 appl
38、iances 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 ser
39、ve 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 explos
40、ive atmosphere (dust, vapour or gas). 2 Normative references This clause of EN 60335-1 is applicable except as follows.
