This Singapore Standard specifies requirements for 13A fused plugs and 13A shuttered socket-outlets for household, commercial and light industrial purposes, with particular references to safety in normal use. The plugs and 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 at 50 Hz.

Two categories of accessories are specified covering normal and rough use. The plugs are intended for use with insulated and sheathed flexible cords complying with SS 236 having conductor cross-sectional areas from 0.5 mm2 to 1.5 mm2 inclusive. Plugs containing switches and devices other than indicator lamps are outside the scope of this standard.
Requirements are specified for 13A shuttered socket-outlets in single or multiple arrangements, with or without associated controlling switches, for flush mounting in suitable enclosures, e.g. to BS 4662 and for surface or panel mounting or for portable use.
