適用范圍：This Singapore Standard specifies requirements for adaptors, including shaver adaptors, having insulating sleeves on the line and neutral plug pins and suitable for use with socket-outlets complying with SS 145, 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 at 50 Hz.The socket contacts of the adaptor shall be able to accept plug pins with the following configurations:(a) 13A plug to SS 145 ;(b) 2.** plug to IEC 83, sheet C5.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 Singapore Standard. Devices incorporating switches, transformers, timers, thermostats, residual current protection or other control means are outside the scope of this standard.NOTE. Requirements for electromagnetic compatibility are not given for the following reasons:An adaptor does not emit intolerable electromagnetic interference since significant electromagnetic disturbances are onlygenerated during insertion and withdrawal which are not continuous.An adaptor is mechanical by nature of construction. The product is therefore immune from electromagnetic interference.
