13A PLUGS, SOCKET-OUTLETS, ADAPTORS AND CONNECTION UNITS - PART 2: SPECIFICATION FOR 13A SWITCHED AND UNSWITCHED SOCKET-OUTLETS (THIRD REVISION)
This Malaysian Standard specifies requirements for 13A 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: Part
1:2011.
Requirements are specified for 13A shuttered socket-outlets in single or multiple
arrangements, with or without associated controlling switches, for flush mounting in suitable
boxes, e.g. complying with BS 4662, or for surface or panel mounting or for portable use.
Fixed socket-outlets are intended for use with cables complying with MS 136 or MS 2112-3
having copper conductors. Portable socket-outlets are intended for use with flexible cords,
complying with MS 140 or MS 2112-5. Socket-outlets containing devices other than fuse links,
switches and indicator lamps are outside the scope of this standard.
NOTES:
1. The titles of the publications referred to in this standard are listed on the inside back cover.
2. In order to maintain safety and interchangeability with plugs and socket-outlets it is necessary that these
products comply with the requirements of Clause 9, Clause 12 and Clause 13 of this standard, 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 are not given for the following reasons.
A switched or unswitched socket-outlet does not emit intolerable electromagnetic interference since significant
electromagnetic disturbances are only generated during insertion and withdrawal which are not continuous.
A switched or unswitched socket-outlet is mechanical by nature of construction. The product is therefore immune
from electromagnetic interference.
