18、l Committees, whose responsibility it is to decide which of these they wish to incorporate in Standards. These recommendations are based on the principles stated hereafter: 1) To supplement the requirements for marking of the appliance and its packaging, given by Essential Requirement1.2.3 of the EU
19、 Directive90/396/EEC Gas appliances, with information corresponding to the countries of destination of the appliance. In view of the differences across Europe with respect to the distribution of gases and the installation of appliances, the identification of the suitability of an appliance is only e
20、xplicit if the appliance category is mentioned in combination with the country of destination. This information has therefore been considered as essential for the safe use of gas appliances. 2) To establish a link between country, category, gas and pressure. The marking of this information, in effec
21、t, constitutes a coherent whole which is intended to give unambiguous information about the use of the appliance concerned. 3) To use symbols in place of texts in the national languages, while establishing two levels of symbols, obligatory (see6.1) or optional (see6.2), in order to take into account
22、 national practices declared by CEN Members. The ad hoc Group Marking of gas appliances has restricted its recommendations to those which apply to all relevant Technical Committees of PC3. Other information can appear on the appliance or on the packaging. All the following texts are only informative
23、 in the context of this CR, but they serve as model texts for appliances standards. 2 Normative references This CEN report incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications a
24、re listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this CEN report only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 437, Test gases Test pres

26、estination a country for which the appliance has been certified and which is specified by the manufacturer as the intended country of destination. At the time of putting the appliance on the market and of installation, the appliance shall be capable of operating, without adjustment or modification,
27、with one of the gases distributed in the country concerned, at the appropriate normal pressure. More than one country can be specified if the appliance, in its current state of adjustment, can be used in each of these countries 3.2 indirect country of destination a country for which the appliance ha
28、s been certified, but for which, in its present state of adjustment, it is not suitable. Subsequent modification or adjustment is essential in order that it can be utilised safely and correctly in that country 3.3 manufacturer the person responsible for designing and manufacturing a product covered
29、by the directive, with a view to placing it on the Community market on his own behalf NOTEThis definition comes from the guide to the implementation of Community harmonization directives based on the new approach and of global approach the comments of which are in the informativeAnnex A of this docu

31、rmly and durably attached to the appliance: the CE marking; the manufacturers name and/or identification symbol; the trade name of the appliance; the type of electrical supply used, if applicable;CR1472:1997 4 BSI 04-1999 the type of gas, in relation to the pressure and/or the pressure couple, for w
32、hich the appliance has been adjusted; any pressure indication shall be identified in relation to the corresponding category index; the direct country or countries of destination of the appliance; the appliance category or categories: if more than one appliance category is specified, each of these ca
33、tegories shall be identified in relation to the appropriate country or countries of destination; the last two digits of the year in which the CE marking was affixed. No other information shall be included on the appliance if this could lead to confusion with regard to the current state of adjustment
34、 of the appliance and the corresponding appliance category (or categories) and the direct country (or countries) of destination. If an adjustment is necessary on the appliance in order to change from one pressure to the other within a pressure couple, only the pressure corresponding to the current a
35、djustment of the appliance shall be indicated. The indelibility of the marking shall be checked by a test carried out in accordance with7.14 of EN60335-1:1994. The identification symbol may be a logo, or a number allocated by the notified body responsible for the production surveillance. 5 Marking o
36、f the packaging The packaging shall carry at least the following information: the type of gas, in relation to the pressure and/or the pressure couple, for which the appliance has been adjusted; any pressure indication shall be identified in relation to the corresponding category index; the direct co
37、untry or countries of destination of the appliance; warnings related to possible restrictions on use, specifying in particular that the appliance has to be installed in areas where there is sufficient ventilation 1) ; the appliance category or categories : if more than one appliance category is spec
38、ified, each of these categories shall be identified in relation to the appropriate country or countries of destination. Information on the appliance to be seen and read once packaged are considered as meeting those requirements. No other information shall be included on the packaging if this could l
39、ead to confusion with regard to the current state of adjustment of the appliance and the corresponding appliance category (or categories) and the direct country (or countries) of destination. If an adjustment is necessary on the appliance in order to change from one pressure to the other within a pr
40、essure couple, only the pressure corresponding to the current adjustment of the appliance shall be indicated. 6 Utilization of symbols on the appliance and packaging 6.1 Information on the appliance and packaging, in accordance with clauses4 and5, which has to be given in the form of symbols 6.1.1 E
41、lectrical supply The marking concerning electrical values shall be in conformity with EN60335-1. 6.1.2 Type of gas In order to represent all of the category indices corresponding to the adjustment of an appliance, the symbol of the reference gas shall be used which is common to all of these indices,
42、 in accordance withTable 1. 1) A cross-reference to the technical instructions is not sufficient.CR1472:1997 BSI 04-1999 5 Table 1 Symbols of the types of gas 6.1.3 Gas supply pressure The gas supply pressure may be expressed uniquely by the numerical value using the unit (mbar). Nevertheless, if it
43、 is necessary to explain the value, the symbol p shall be used. 6.1.4 Country of destination In accordance with EN23166, the names of countries shall be represented by the following codes: 6.1.5 Category The category can be expressed uniquely by its designation in accordance with EN437. Nevertheless
44、, if it is necessary to explain it, the term “Category” shall be symbolized by Cat. 6.2 Other optional information The symbols given below are not obligatory, but are recommended under the title “preferential”, and to the exclusion of any other symbol, to avoid the use of many and different markings
