22、to as adapters, for industrial use comprising a housing incorporating a plug and socket-outlets which can be used to connect one or two plugs of the domestic type to an industrial 2P +16 A, 250 V 6 h, type socket-outlet. This standard shall be used jointly with standards EN 60309-1, Plugs, socket-ou
23、tlets and couplers for industrial purposes Part 1: General requirements, EN 60309-2, Plugs, socket-outlets and couplers for industrial purposes Part 2: Dimensional interchangeability requirements for pin and contact-tube accessories of harmonized configurations, and with the relevant national standa
24、rds for socket-outlets for household and similar use (listed in annex AA). The clauses in this standard amend or replace the clauses of the above mentioned standard EN 60309-1. 1 Scope Replacement: This standard applies to conversion adapters intended mainly for industrial use, comprising a housing
25、of insulating material which incorporates an industrial 2 P +, 16 A, 6 h 250 V type plug part (Table 104 in EN 60309-2) and one or two socket-outlets in accordance with the relevant national standards for socket-outlets for household and similar use, with a rated current up to 16 A, intended mainly
26、for industrial use either indoors or outdoors. NOTEAdapters with three socket-outlets or a different type of plug part, according to EN 60309-2, are under consideration. This standard applies to all applications where the ambient temperature does not normally exceed 40 8C. The use of these adapters
27、on building sites, for agricultural, commercial and domestic applications is not precluded but care should be taken in considering protecting devices in use. Adapters are for temporary use only. In locations where special conditions prevail, for example on board ship or where explosions are liable t
28、o occur, additional requirements may be necessary. 2 Definitions This clause of EN 60309-1 is applicable with the following additions. 2.101 adapter portable accessory which allows the connection of one or more types of plug to a socket-outlet not designed to accept such plugs 2.101.1 single adapter
29、 adapter having a single plug function and a single socket-outlet function 2.101.2 double adapter adapter having a single plug function and two socket-outlet functions. The two socket-outlets may or may not comply with the same dimensional requirements 2.102 rated current of an adapter the rated cur
30、rent of an adapter is: the rated current of the plug part of the adapter; the sum of the rated currents of the plugs that can be inserted into the adapter, whichever is the lower 2.103 serviceable adapter an adapter which can be disassembled, using ordinary tools (e.g. screwdrivers, etc.) for replac
31、ement or maintenance 2.104 non-serviceable adapter an adapter which cannot be disassembled using ordinary tools (e.g. screwdrivers, etc.) without rendering it permanently useless 3 Normative references This clause of EN 60309-1 is applicable with the following additions.

35、his standard are type tests. The parts of adapters are tested, unless otherwise specified, in accordance with the requirements of the relevant standard, as applicable; e.g. plug part is tested according to EN 60309-2 and socket-outlet parts are tested according to the relevant national standards. 4.
36、2.4 Replacement: Unless otherwise specified, one set of three specimens shall be subjected to all the tests. 4.2.5 Replace the first paragraph of the note by: NOTEIn general, it will only be necessary to repeat the tests which caused the failure, unless the specimens fail in test of clause 21, in wh
37、ich case tests shall be repeated from clause 20 onwards.

38、s 5 Standard ratings Replacement: 5.1 Rated voltage: The recommended rated voltage is 250 V. 5.2 Rated current: Rated current: 10 A, 13 A , 15 A and 16 A. 6 Classification Replacement: 6.1 Adapters are classified: 6.1.1 According to the degree of protection against harmful ingress of water in accord
39、ance with EN 60529: IPX0 (non-protected); IP $ X4 (protected). NOTEThe degree of protection of the socket-outlets for industrial use, when used in conjunction with an adapter, will revert to the protection rating of the adapter if this is less than that of the socket-outlet. 6.1.2 According to the t
40、ype of construction: serviceable adapters; non-serviceable adapters. 7 Marking Replacement: 7.1 Adapters shall be marked with: rated current in amperes; rated operating voltage or range in volts; symbol for nature of supply; either the name or trade mark of the manufacturer or of the responsible ven
41、dor; type reference, which may be a catalogue number; symbol for degree of protection (IP code); symbol indicating the position of the earthing contact (plug part side); wording for temporary use only. For adapters with degree of protection IPX0 is required a leaflet indicating to be aware in use of
42、 it because it reduces the degree of protection of the industrial socket-outlet in which will be inserted and that it shall not be used in environment with an explosion hazards. NOTE 1 This wording shall be written in the official language of the country of intended use. Compliance is checked by ins
43、pection. NOTE 2 Marking 10/16 shall be accepted as indication for socket-outlet parts in accordance with standard CEE 7. The symbol indicating the position of the earthing contact shall be placed before or above the figure indicating the rated operating voltage, and separated from it by a line. Thes
44、e markings shall be placed after that for rated current, separated from it by a dash, if an oblique line separates the symbol indicating the position of the earthing contact from the figure for the rated operating voltage. If a symbol for nature of supply is used, it shall be placed next to or below
45、 the marking for rated operating voltage. The marking for rated current, position of the earthing contact, rated operating voltage(s) and the nature of the supply may accordingly be as follows: 16 A 2 6 h/250 V, or 16 2 6 h/250, or 16 2 6h 250 7.2 When symbols are used, they shall be as follows: Aam
46、peres Vvolts alternating current earth IPXX degree of protection according to EN 60529 For marking of rated current(s) and rated operating voltage(s) or range(s), figures may be used alone. Compliance is checked by inspection. 7.3 The marking specified in 7.1 shall be readily visible when the adapte
47、r is equipped and ready for use, with the exception of the wording for temporary use only, which shall also be visible when the adapter is in use. NOTE 1 The term ready for use does not imply that the adapter is in engagement with its complementary accessory. NOTE 2 The marking for rated current, na
48、ture of supply, rated operating voltage and the name, trade mark of the manufacturer or the responsible vendor, may be repeated on the lid, if any. Compliance is checked by inspection.

This symbol shall be placed close to the corresponding terminals, and should not be placed on screws, washers or other removable parts. 7.5 Markings shall be indelible and easily legible. Compliance is checked by inspection and by the following test. After the humidity treatment in clause 18 the marking shall be rubbed vigorously by hand for 15 s with a piece of cloth soaked in water and again for 15 s
