16、accessories. A list of organizations represented on this committee can be obtained on request to its secretary.Relationship with other publicationsBS 1363 comprises five parts covering the following.Part 1: Specification for rewireable and non-rewireable 13 A fused plugs;Part 2: Specification for 13

17、 A switched and unswitched socket-outlets;Part 3: Specification for adaptors;Part 4: Specification for 13 A fused connection units switched and unswitched;Part 5: Specification for fused conversion plugs.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright)

18、type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation, and general informative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not

20、 1363 specifies requirements, with particular reference to safety in normal use, for 13 A, fused, conversion plugs for household, commercial and light industrial purposes.The scope of the standard covers two-pole plus earth conversion plugs that are either reusable or non-reusable and that are suita

21、ble for the connection of non-BS 1363 type plugs, conforming to a recognized standard, to socket-outlets conforming to BS 1363-2. The scope of this standard is limited to devices with the following characteristics: that have insulating sleeves on line and neutral pins; that have one plug portion and

22、 one set of contacts intended to connect to a non-BS 1363 type plug that conforms to the dimensional requirements of a standard listed in IEC TR 60083; that are suitable for the connection of electrical equipment in a.c. circuits only, operating at voltages not exceeding 250 V r.m.s. at 50 Hz; that

23、may have the un-terminated metal earth pin replaced with a similarly dimensioned insulated shutter opening device (ISOD) designed to operate the shutter mechanism of a socket-outlet conforming to BS 1363-2.NOTE A metal earth pin can be brass, copper, phosphor-bronze or other metal at least equivalen

24、t with regard to its conductivity, resistance to abrasion, and resistance to corrosion.Two categories of conversion plugs are specified, covering normal and rough use.Conversion plugs specified in this standard are intended for the connection of loads to socket outlets; they are not intended for the

25、 connection of electrical power generators to socket outlets.Conversion plugs incorporating switches, transformers, thermostats, or other control means are outside the scope of this Part of BS 1363.This standard also does not cover: non-BS 1363 type conversion plugs, i.e. with a contact set to fit 1

26、3 A plugs, and a male plug portion suitable for a non-BS 1363 type socket outlet; or adaptors (as to which, see BS 1363-3).BS 1363-5:20082 BSI 20082 Normative referencesThe following referenced documents are indispensable for the application of this document.
