13A PLUGS, SOCKET-OUTLETS, ADAPTORS AND CONNECTION UNITS - PART 1: SPECIFICATION FOR REWIRABLE AND NON-REWIRABLE 13A FUSED PLUGS (THIRD REVISION)
This Malaysian Standard specifies requirements for 13 A fused plugs having insulating
sleeves on line and neutral pins, for household, commercial and light industrial purposes, with
particular reference to safety in normal use. The plugs are suitable for the connection of
portable appliances, sound-vision equipment, luminaires, etc. in alternating current circuits
only, operating at voltages not exceeding 250 V r.m.s. at 50 Hz.
Requirements are specified for plugs incorporating a fuse link complying with MS 1428 or BS
1362. The plugs may be rewirable or non-rewirable complete with flexible cord. Two
categories of plugs are specified covering normal and rough use. Rewirable plugs are
intended for use with flexible cords complying with MS 140 or MS 2112-5 or IEC 60245-4
having conductor cross-sectional areas from 0.5 mm2 to 1.5 mm2 inclusive.
NOTE. See 19.1.
Non-rewirable plugs are intended for use with flexible cords having conductor cross-sectional
areas not exceeding 1.5 mm2.
NOTE. See 19.4.
This Malaysian Standard also applies to non-rewirable 13 A plugs which have the brass earth
pin replaced with a similarly dimensioned protrusion made of insulating material designated
as an insulated shutter opening device (ISOD) designed to operate the shutter mechanism of
a socket-outlet conforming to MS 589.
Plugs containing switches and devices other-than indicator lamps are outside the scope of
this standard.
NOTES:
1. Brass can be copper, phosphor-bronze or other metal at least equivalent with regard to its conductivity, resistance
to abrasion and resistance to corrosion.
2. The titles of the publications referred to in this standard 589 are listed on the inside back cover.
3. 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, 12 and 13 of this standard, however their body outline need not be limited
at a distance of 6.35 mm from the plug engagement surface.
4. Requirements for electromagnetic compatibility are not given for the following reasons.
A plug does not emit intolerable electromagnetic interference since significant electromagnetic disturbances are only
generated during insertion and withdrawal which are not continuous.
A plug is mechanical by nature of construction. The product is therefore immune from electromagnetic interference.
