This Part of BS 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 suitable 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 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 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 equivalent 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
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 13 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).
