22、reword The CENELEC questionnaire procedure, performed for finding out whether or not the International Standard IEC 320-2-2:1990, as corrected by corrigendum August 1990, could be accepted without textual changes, has shown that some CENELEC common modifications were necessary for the acceptance as
23、European Standard. The reference document, together with the common modifications prepared by the CENELEC Reporting Secretariat SR 23G, was submitted to the CENELEC members for formal vote. The text of the draft was approved by CENELEC as EN 60320-2-2 on 25 June 1991. The following dates were fixed:
24、 For products which have complied with the relevant national standard before 1992-07-01, as shown by the manufacturer or by a certification body, this previous standard may continue to apply for production until 1997-07-01. Annexes designated “normative” are part of the body of the standard. In this
25、 standard, Annex ZA is normative.

30、“appliance coupler”, “connector” or “appliance inlet” appear, they should be deleted and replaced with “interconnection coupler”, “plug connector” or “appliance outlet” respectively. 1 Scope This clause of EN 60321-1 is replaced as follows: This standard is applicable to: two-pole interconnection co
31、uplers for a.c. only, with and without earthing contact, with a rated voltage not exceeding 250 V and a rated current not exceeding 10 A, for household and similar appliances and equipment and intended for the interconnection of the electrical supply to electrical appliances or equipment for 50 Hz o
32、r 60 Hz supply; interconnection cord sets incorporating plug connectors of such interconnection couplers. Appliance outlets integrated in or incorporated in appliances or other equipment are within the scope of this standard. The dimensional and general requirements of this standard apply to such ou
33、tlets, but certain tests may not be relevant. The requirements for plug connectors are based on the assumption that the temperature of the socket contacts of the corresponding appliance outlets does not exceed 65 C (cold conditions). Interconnection couplers complying with this standard are suitable
34、 for use at ambient temperatures not normally exceeding 25 C, but occasionally reaching 35 C. Interconnection couplers complying with the standard sheets in this standard are intended for the interconnection of appliances or equipment having no special protection against moisture; for the interconne
35、ction of other appliances or equipment and of an appliance or equipment which is subject to spillage of liquid in normal use, additional requirements are necessary. Special constructions may be required: in locations where special conditions prevail as, for example, in ships, vehicles and the like;
36、in hazardous locations, for example, where explosions are liable to occur. 2 Definitions This clause of EN 60320-1 applies with the following additions: Additional definitions: 2.101 An interconnection coupler is a means enabling the connection and disconnection at will of an appliance or equipment
37、to a flexible cable or cord leading to another appliance or equipment. it consists of two parts: a plug connector, which is the part integral with, or intended to be attached to, the flexible cable or cord; an appliance outlet, which is the part integrated or incorporated in the appliance or equipme
38、nt or intended to be fixed to it, and from which the supply is obtained. An appliance outlet integrated in an appliance or equipment is an appliance outlet (the shroud and bottom of) which is formed by the housing of the appliance or equipment. An appliance outlet incorporated in an appliance or equ
39、ipment is a separate appliance outlet built in or fixed to an appliance or equipment. 2.102 An interconnection cord set is an assembly consisting of a flexible cable or cord with an non-rewirable plug connector and a non-rewirable connector, intended for the interconnection of the electrical supply
40、from one electrical appliance or equipment to another. 2.3 Replacement The term “accessory” is used as a general term covering plug connectors and/or appliance outlets. 3 General requirements This clause of EN 60320-1 is replaced as follows: Interconnection couplers shall be so designed and construc
41、ted that in normal use their performance is reliable and without danger to the user or surroundings. In general, compliance is checked by carrying out all the tests specified.

42、 4 BSI 05-1999 4 General notes on tests This clause of EN 60320-1 applies amended as follows: 4.4 Replacement: Unless otherwise specified, plug connectors and appliance outlets are tested in conjunction with an appropriate appliance outlet or plug connector complying with this standard. 4.5 Replacem
43、ent: For appliance outlets, six samples are required, three of which are subjected to the tests specified with the exception of those of Clauses 13, 14, 15, 18, 19 and 20; the other three samples are subjected to the tests of Clauses 13, 14, 15, 18, 19 and 20 (including the repetition of the test of
44、 Sub-clause 15.2). For plug connectors, nine samples are required, three of which are subjected to the tests specified with the exception of those of Clauses 13, 14 and 16 and Sub-clauses 21.4 and 23.2; three other samples are subjected to the tests of Clauses 13, 14 and 16; the other three samples
45、are subjected to the test of Sub-clause 21.4. For plug connectors of rubber or similar material, two additional samples are required which are subjected to the test of Sub-clause 23.2.1. For plug connectors of polyvinyl chloride (PVC) or similar material, two additional samples are subjected to the
46、test of Sub-clause 23.2.3. Accordingly, for plug connectors the total number of samples is: 5 Standard ratings This clause of EN 60320-1 applies amended as follows: 5.2 Replacement: Standard rated currents are 2,5 A and 10 A as specified in Sub-clause 8.1 of this standard. 6 Classification This clau
47、se of EN 60320-1 applies amended as follows: Replacement: 6.1 Interconnection couplers are classified according to the type of appliance or equipment to be connected: interconnection couplers for Class I equipment; interconnection couplers for Class II equipment. For a description of the classes, se
48、e IEC Publication 536. 6.2 Plug connectors are, moreover, classified according to the method of connecting the flexible cable or cord: rewirable plug connectors; non-rewirable plug connectors. 7 Marking This clause of EN 60320-1 applies amended as follows: 7.1 Replacement: Plug connectors shall be m
49、arked with: rated current in amperes; rated voltage in volts; symbol for nature of supply; name, trade mark or identification mark of the manufacturer or of the responsible vendor; type reference.
