23、ontrolled Copy, (c) BSIBS 1363-3:1995 BSI 9 October 2003 iii Foreword This part of BS 1363 has been prepared by Technical Committee PEL/23. This part of BS 1363 supersedes BS 1363-3:1989. BS 1363 comprises four parts covering the following. Part 1: Rewirable and non-rewirable 13 A fused plugs; Part
24、2: Switched and unswitched socket-outlets; Part 3: Adaptors; Part 4: 13 A fused connection units: switched and unswitched. This part of BS 1363 is effective immediately. The provisions introduced by amendment No. 2:2003 are also effective immediately, but for certification purposes, the version of t
25、his standard incorporating only amendment No. 1:1997 and Corrigendum No. 1:2002 remains current until 31 December 2005. NOTE In order to prevent confusion with BS 1363:1984, the figure and clause numbers have been retained. This publication does not purport to include all the necessary provisions of
26、 a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i to iv, pages 1 to 76, an inside back cover and a back c
27、over. The BSI copyright notice displayed in this document indicates when the document was last issued. Sidelining in this document indicates the most recent changes introduced by amendment.

29、 the line and neutral plug pins and suitable for use with socket-outlets complying with BS 1363-2, with particular reference to safety in normal use. Adaptors specified in this part of BS 1363 are intended for household, commercial and light industrial purposes. The adaptors are suitable for the con
30、nection of portable appliances, sound-vision equipment, luminaires, etc., in a.c. circuits only, operating at voltages not exceeding 250 V r.m.s. at 50 Hz. Assemblies comprising a plug and one or more portable socket-outlets connected together by a flexible cord or cable are not considered to be ada
31、ptors according to this part of BS 1363. Devices incorporating switches, transformers, timers, thermostats or other control means are outside the scope of this part of BS 1363. NOTE 1 The titles of the publications referred to in this standard are listed on the inside back cover. NOTE 2 In order to
32、maintain safety and interchangeability with plugs and socket-outlets it is necessary that these products comply with the requirements of Clause 9, Clause 12 and Clause 13, however their body outline need not be limited at a distance of 6.35 mm from the plug engagement face. NOTE 3 Requirements for e
33、lectromagnetic compatibility are not given for the following reasons. An adaptor does not emit intolerable electromagnetic interference since significant electromagnetic disturbances are only generated during insertion and withdrawal which are not continuous. An adaptor is mechanical by nature of co
34、nstruction. The product is therefore immune from electromagnetic interference. 2 Conditions of use Adaptors shall be suitable for use under the following conditions: a) an ambient temperature in the range p5 C to +40 C, the average value over 24 h not exceeding 25 C; NOTE Under normal conditions of
35、use, the available cooling air is subject to natural atmospheric variations of temperature and hence the peak temperature occurs only occasionally during the hot season, and on those days when it does occur it does not persist for lengthy periods. b) a situation not subject to exposure to direct rad
36、iation from the sun or other source of heat likely to raise temperatures above the limits specified in a); c) an altitude not exceeding 2 000 m above sea level; d) an atmosphere not subject to abnormal pollution by smoke, chemical fumes, rain, spray, prolonged periods of high humidity or other abnor
37、mal conditions. This is the equivalent to pollution degree 2, see Annex F, and overvoltage category III, see Annex E. 3 Terms and definitions For the purposes of this part of BS 1363 the following definitions apply. NOTE Where the terms voltage and current are used, they imply r.m.s. values, unless
38、otherwise, stated. 3.1 adaptor a portable accessory having plug pins, intended to engage with the contacts of a BS 1363 socket-outlet, and having socket-outlet contacts to accommodate one or more plugs 3.2 adaptor socket-outlet a set of contacts forming part of an adaptor and designed to engage with
39、 the pins of a corresponding plug 3.3 multiway adaptor an adaptor having more than one set of socket contacts (the socket contacts may or may not be of the same type or rating as the plug pin portion) 3.4 non-rewirable adaptor an adaptor as in 3.7 or 3.8, so constructed that it forms a complete unit

42、 plug a fused adaptor having one or more socket-outlets and provision for the connection of a flexible cord to a portable appliance, in parallel with the socket-outlet 3.8 intermediate adaptor a fused adaptor having one or more socket-outlets and provision for the connection of a flexible cord to a
43、remote control device in series with the socket-outlet 3.9 conversion adaptor a fused adaptor having one or more sets of socket contacts of a type or rating differing from the plug pin portion 3.10 shaver adaptor a fused conversion adaptor specifically designed to have a single socket-outlet capable
44、 of accepting the plugs normally fitted to electrical shavers as referred to in Clause 18 3.11 shutter a movable device arranged to shield the current carrying socket-outlet contacts automatically when a corresponding plug is removed 3.12 terminal a means by which the user can make an electrical con
45、nection between the appropriate flexible cord and the conducting parts of the adaptor without the use of special tools 3.13 screw-type terminal a terminal in which the connection is made directly by means of screws or nuts of any kind or indirectly through an intermediate metal part such as a washer
46、, clamping plate or anti spread device on which the screw bears directly NOTE The following are examples of screw-type terminals. a) A pillar terminal is a terminal in which the conductor is inserted into a hole or cavity, where it is clamped under the shank of the screw or screws. b) A screw termin
47、al is a terminal in which the conductor is clamped under the head of the screw. c) A stud terminal is a terminal in which the conductor is clamped under a nut. 3.14 termination a means by which an electrical connection can be made between the appropriate flexible cord and the conducting part of the
