13 A Plugs, socket-outlets, adaptors and connection units - Part 2: Specification for 13 A switched and unswitched socket-outlets (Fourth revision)
This Malaysian Standard specifies requirements for 13 A switched and unswitched shuttered
socket-outlets for household, commercial and light industrial purposes, with particular
reference to safety in normal use. The socket-outlets are suitable for the connection 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 using plugs in accordance with MS 589-1.
Additional requirements are included for socket-outlets suitable for electric vehicle charging.
Requirements are specified for 13 A shuttered socket-outlets in single or multiple
arrangements, with or without associated controlling switches, for flush mounting in suitable
boxes, e.g. conforming to BS 4662, or for surface or panel mounting or for portable use. Fixed
socket-outlets are intended for use with cables conforming to MS 2112-3 or MS 2112-4 or
BS 6004:2012 and cables to the relevant part of BS EN 50525 (see Annex H), having copper
conductors. Portable socket-outlets are intended for use with flexible cables conforming to
MS 2112-5 or relevant part of BS EN 50525. Socket-outlets incorporating fuse links, switches
and indicator lamps are included within the scope of this part of MS 589. Socket-outlets
incorporating electronic components as detailed in Annex J are included within the scope of
this part of MS 589.
Socket-outlets conforming to this standard are shuttered and therefore do not require the use
of additional means to shield the current-carrying contacts when no plug is present in the
socket-outlet.
NOTES:
1. The titles of the publications referred to in this part of MS 589 are listed in the bibliography.
2. In order to maintain safety and interchangeability with plugs and socket-outlets it is necessary that
these products conform to the requirements of Clauses 9 and 13 of this part of MS 589, however their
body outline need not be limited at a distance of 6.35 mm from the plug engagement surface.
3. Requirements for electromagnetic compatibility for socket-outlets that incorporate electronic devices
are given in Annex J.
A socket-outlet that does not incorporate electronic devices does not emit intolerable
electromagnetic interference since significant electromagnetic disturbances are only
generated during insertion and withdrawal which are not continuous.
A socket-outlet that does not incorporate electronic devices is mechanical by nature of
construction. The product is therefore immune from electromagnetic interference.
