Materials of insulated electric cables and flexible cord — Part 1: Conductors
Description
This part of BOS 550 specifies requirements for copper and aluminium conductors used in insulated electric cables and flexible cords.
It covers:
a)solid circular conductors,
b)stranded and flexible circular conductors, c)solid shaped conductors,d)stranded shaped conductors,of the sizes included in various specifications for insulated electric cables and flexible cords published by the Botswana Bureau of Standards.
It does not cover bare conductors for overhead transmission lines, conductors for telecommunication or radio-frequency cables, or conductors used as the supporting core in aerial bundled conductor systems. NOTE As this part of BOS 550 covers only the conductor(s) of a finished cable or flexible cord, the quality evaluation of such conductor(s) will form part of the quality evaluation of any consignment or lot of cable or cord. Any sampling plans and criteria for compliance given in a standard that covers the cables or cords will, therefore, apply to inspections and tests carried out in terms of this part of BOS 550.
