19、 industrial 2P + 16 A, 250 V, 6 h, type socket-outlet. This standard shall be used jointly with EN 60309-1 “Plugs, socket-outlets and couplers for industrial purposes - Part 1: General requirements“, EN 60309-2 “Plugs, socket-outlets and couplers for industrial purposes Part 2: Dimensional interchan
20、geability requirements for pin and contact-tube accessories“ and with the relevant national standards 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 EN 60309-1. BS EN 50250:2002+A1:2015 EN 50250:
21、2002+A1:2015 (E) 4 1 Scope Replacement: This standard applies to conversion adaptors intended mainly for industrial use, comprising a housing of insulating material which incorporates an industrial 2P + , 16 A, 6 h 250 V type plug part (Table 104 in standard EN 60309-2) and one or two socket-outlets
22、 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 for industrial use either indoors or outdoors. Adaptors can be used in conjunction with socket-outlets and/or connectors This standard applies to all
23、 applications where the ambient temperature does not normally exceed 40 C. The use of these adaptors on building sites, for agricultural, commercial and domestic applications is not precluded but care should be taken in considering protecting devices in use. Adaptors are for temporary use only. In l
24、ocations where special conditions prevail, for example on board ship or where explosions are liable to occur, additional requirements may be necessary. 2 Normative references This clause of EN 60309-1 is applicable with the following additions: EN 60309-1 1999 Plugs, socket-outlets and couplers for

31、 be so designed and constructed 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. BS EN 50250:2002+A1:2015 EN 50250:2002+A1:2015 (E) 6 4.2 General notes on tests 4.2.1 Replacemen
32、t: Tests according to this standard are type tests. The parts of adaptors 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
33、 national standards. 4.2.4 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: NOTE In general, it will only be necessary to repeat the tests which caused the failure, unless the specimens fail in
34、test of Clause 21, in which case tests shall be repeated from Clause 20 onwards. Addition: 4.2.101 If gauges are used, these shall be of hardened steel, and all corners shall be slightly rounded-off with a maximum radius of 0,1 mm and the surface-finish for all measurement-surfaces shall be N8 min,
35、unless otherwise specified. 5 Standard ratings Replacement: 5.1 Rated voltage: The rated voltage is 250 V . 5.2 Rated current: Rated current: 13 A, 15 A and 16 A. NOTE 13 A rated current is allowed only in countries where plugs are fused. 6 Classification Replacement: 6.1 Adaptors are classified: 6.

BS EN 50250:2002+A1:2015 EN 50250:2002+A1:2015 (E) 7 NOTE The degree of protection of the socket-outlets for industrial use, when used in conjunction wi
37、th an adaptor, will revert to the protection rating of the adaptor if this is less than that of the socket-outlet. 6.1.2 According to the type of construction - serviceable adaptors, - non-serviceable adaptors. 7 Marking Replacement: 7.1 Adaptors shall be marked with - rated current in amperes, - ra
38、ted operating voltage or range in volts, - symbol for nature of supply, - either the name or trade mark of the manufacturer or of the responsible vendor, - type reference, which may be a catalogue number, - symbol for degree of protection (IP code), - symbol indicating the position of the earthing c
39、ontact (plug part side), - wording “FOR TEMPORARY USE ONLY“. Adaptors shall be provided with manufacturer instruction stating that - for adaptors having a degree of protection IPX0 the user should be aware that the degree of protection of the industrial socket-outlet in which it will be inserted wil
40、l be reduced, - adaptors shall not be used in explosive atmosphere. NOTE 1 This wording should be written in the official language of the country of intended use. Compliance is checked by inspection. NOTE 2 Marking 10/16 should be accepted as indication for socket-outlet parts in accordance with sta
41、ndard 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. These markings shall be placed after that for rated current, separated from it by a dash, if an oblique line sep
42、arates 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 the marking for rated operating voltage. BS EN 50250:2002+A1:2015 EN 50250:2002+A1:2015 (E) 8 The marking f

44、 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 adaptor is equipped and ready for use, with the excepti
45、on of the wording “FOR TEMPORARY USE ONLY“ which shall also be visible when the adaptor is in use. NOTE 1 The term “ready for use“ does not imply that the adaptor is in engagement with its complementary accessory. NOTE 2 The marking for rated current, nature of supply, rated operating voltage and th
46、e name, trade mark of the manufacturer or the responsible vendor, may be repeated on the lid, if any. Compliance is checked by inspection. 7.4 In serviceable adaptors the earthing contacts shall be indicated by the symbol . This symbol shall be placed close to the corresponding terminals, and should
47、 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 soake
48、d in water and again for 15 s in a piece of cloth soaked in petroleum spirit. Special attention is paid to the marking of the name, trade mark or identification mark of the manufacturer or the responsible vendor and to that of the nature of supply and to the warning note. NOTE It is recommended that
49、 the petroleum spirit used is of a type consisting of a solvent hexane with an aromatic content of maximum 0,1 volume percentage, a kauri-buthanol value of 29, an initial boiling point of approximately 65 C, a dry point of approximately 69 C and a density of approximately 0,68 g/cm3.
