13、 0.017 241 mVm is said to have a conductivity of 100 % IACS (see IEC Publication 60028). 1 Scope This British Standard specifies requirements for electric cable soldering sockets of copper or copper alloy for connecting to each other or to apparatus. It specifies material for and dimensions of socke
14、ts suitable for cables containing conductors from 6 mm2up to and including 1200 mm2 cross-sectional area in accordance with BS 6360, Tables 1 and 2. The sockets are also suitable for use with flexible conductors which conform to the requirements of BS 6360, Tables 3 and 4. However, some such conduct
15、ors will require a socket one size larger than conductors of the same nominal cross-sectional area but which conform to the requirements of Table 2 of BS 6360. The sockets are not intended for use with sector-shaped solid aluminium conductors. 2 Normative references The following normative documents
16、 contain provisions which, through reference in this text, constitute provisions of this British Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. For undated references, the latest edition of the publication referred to applies. BS 14

The interior and exterior surfaces of tubular cable sockets shall be tinned either by electroplating in accordance with BS 1872 classification number Sn 2C, or by hot dip tinning. The solder used for hot dip tinning shal
27、l be Alloy designation 5 as specified in BS EN 29453, and the flux used for the purpose of tinning shall be non-corrosive. The average thickness of tin coating shall be not less than 10 mm and the coating shall be such as to ensure efficient soldering without further cleaning. 8.2 The stud hole in t
28、he palm of the forged or cast cable socket shall, unless otherwise specified, have a nominal diameter, dimension E, corresponding to the appropriate size of standard stud as specified in column 5 of Table 1. In no case shall the stud hole have a nominal diameter exceeding the value of dimension E, c
29、orresponding to the appropriate largest stud size as specified in column 5 of Table 1. The stud hole shall be free from burrs. 8.3 The stud hole in the palm of the tubular cable socket shall, unless otherwise specified, have a nominal diameter, dimension E, corresponding to the appropriate size of s
30、tandard stud in column 5 of Table 2. In no case shall the stud hole have a nominal diameter exceeding the value of dimension E corresponding to the appropriate largest stud size in column 5 of Table 2.
