21、I 9 October 2003 iii Foreword This part of BS 1363 has been prepared by Technical Committee PEL/23. This part of BS 1363, together with BS 1363-2:1995, supersedes BS 1363:1984. BS 1363 comprises four parts covering the following. Part 1: Rewirable and non-rewirable 13 A fused plugs; Part 2: Switched
22、 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 this standard
23、 incorporating only amendment No. 1:1997 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 a contract. Users are responsible for
24、its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Attention is drawn to Statutory Instrument 1768, 1994. Summary of pages This document comprises a front cover, an inside front cover, pages i to iv, pages 1 to 62, an inside back co
25、ver and a back cover. 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. Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Thu Nov 23 10:08:51
26、GMT+00:00 2006, Uncontrolled Copy, (c) BSIiv blank Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Thu Nov 23 10:08:51 GMT+00:00 2006, Uncontrolled Copy, (c) BSIBS 1363-1:1995 BSI 9 October 2003 1 1 Scope This part of BS 1363 specifies requirements for 13 A fused plugs havi
27、ng insulating sleeves on line and neutral pins, for household, commercial and light industrial purposes, with particular reference to safety in normal use. The plugs are suitable for the connection of portable appliances, sound-vision equipment, luminaires, etc. in a.c. circuits only, operating at v
28、oltages not exceeding 250 V r.m.s. at 50 Hz. Requirements are specified for plugs incorporating a fuse link complying with BS 1362:1973. The plugs may be rewirable or non-rewirable complete with flexible cord. Two categories of plugs are specified covering normal and rough use. Rewirable plugs are i
29、ntended for use with flexible cords complying with BS 6500:2000 having conductor cross-sectional areas from 0.5 mm 2to 1.5 mm 2inclusive. NOTE 1 See 19.1. Non-rewirable plugs are intended for use with flexible cords having conductor cross-sectional areas not exceeding 1.5 mm 2 . NOTE 2 See 19.4. Thi
30、s standard also applies to non-rewirable 13 A plugs which have the brass earth pin replaced with a similarly dimensioned protrusion made of insulating material designated as an insulated shutter opening device (ISOD) designed to operate the shutter mechanism of a socket-outlet conforming to BS 1363-
31、2. Plugs containing switches and devices other than indicator lamps are outside the scope of this part of BS 1363. NOTE 3 The titles of the publications referred to in this part of BS 1363 are listed on the inside back cover. NOTE 4 In order to maintain safety and interchangeability with plugs and s
32、ocket-outlets it is necessary that these products comply with the requirements of Clause 9, 12 and 13 of this part of BS 1363, however their body outline need not be limited at a distance of 6.35 mm from the plug engagement face. NOTE 5 Requirements for electromagnetic compatibility are not given fo
33、r the following reasons. A plug does not emit intolerable electromagnetic interference since significant electromagnetic disturbances are only generated during insertion and withdrawal which are not continuous. A plug is mechanical by nature of construction. The product is therefore immune from elec
34、tromagnetic interference. 2 Conditions of use Plugs 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 use, the available cooling air is subject to natural atm
35、ospheric 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 radiation from the sun or other source of heat likely to ra
36、ise 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 abnormal conditions. This is equivalent to pollution degree 2
37、, see Annex E, and overvoltage category III, see Annex D. 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 otherwise stated. 3.1 plug a portable fused device having pr
