13 A plugs, socket-outlets, adaptors and connection units - Part 3: Specification for adaptors (Third revision)
This Malaysian Standard specifies requirements for adaptors having insulating sleeves on the
line and neutral plug pins and suitable for use with socket-outlets complying with MS 589-2,
with particular reference to safety in normal use. Adaptors specified in this standard are
intended for household, commercial and light industrial purposes. The adaptors 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.
This standard also applies to shaver adaptors 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 589-2.
NOTE 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.
Assemblies comprising a plug and one or more portable socket-outlets connected together by
a flexible cord or cable are not considered to be adaptors according to this standard. Devices
incorporating switches, transformers, timers, thermostats or other control means are outside
the scope of this standard.
NOTES:
2. The titles of the publications referred to in this standard 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, Clause 12 and Clause 13, 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. An adaptor does not
emit intolerable electromagnetic interference since significant electromagnetic disturbances are only generated
during insertion and withdrawal which are not continuous.
An adaptor is mechanical by nature of construction. The product is therefore immune from electromagnetic
interference.
