- 1 - Unofficial Translation In the event of any doubt or misunderstanding arising form this translation, the standard in Thai will be held to be authoritative TIS 166-2549 (2006) Thai Industrial Standard for PLUGS AND SOCKET-OUTLETS FOR HOUSEHOLD AND SIMILAR PURPOSES : PLUGS AND SOCKET-OUTLETS WITH RATED VOLTAGE NOT EXCEEDING 250 V 1. Scope 1.1 This standard applies to plugs and fixed socket-outlets or portable socket- outlets for a.c. only, with a rated voltage being not more than 250 V and a rated current not more than 16 A, intended for household and similar purposes, either indoors or outdoors, at ambient temperatures not normally exceeding 40 C. 1.2 This standard also applies to plugs incorporated in cord sets, to plugs and portable socket-outlets incorporated in cord extension sets and to plugs and socket-outlets which are components of an appliance, unless otherwise stated in the standard for the relevant appliance. This standard does not apply to - plugs, socket-outlets and couples for industrial purposes; - appliance couplers; - plugs, fixed and portable socket-outlets for(extra-low voltage; ELV) - fixed socket-outlets combined with fuses, automatic switches; etc. - requirements for flush mounting boxes: however, it covers only those requirements for surface-type mounting boxes which are necessary for the tests on the socket-outlet. - 2 - NOTE 1. Extra-low voltage values are specified in IEC 60364-4-41. 2. Pilot lights incorporated in the socket-outlets are allowed provided that the pilot lights comply with the relevant standard. 3. Socket-outlets complying with the standard are only suitable for incorporation in equipment in such a place that it is unlikely that the surrounding temperature exceeding 40 Celsius degree In locations where special conditions prevail, such as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required. 2.

(2) Two poles plugs for equipment of class II Dimensions and pin configuration shall be as figure 2. (3) Two poles socket-outlets with grounding pin Dimensions and pin configuration shall be as figure 3. and figure 4. Compliance is checked by inspection and by applying the specified in annex A. - 4 - Dimensions in millimeters Figure explanation ? The symbol (the symbol No.5019a of IEC 60417) and the letter “L” and “N”shall be marked on the engagement face of the plug. The thickness of the symbol and character shall be between 0.2 and 0.4 mm. The terminal inside the body of the rewirable plugs shall also be indicated by the symbol. ? The distance between the engagement face and the cord guard (if any) shall be at least 18 mm. ? Within5 millimetres, measured from the engagement face, the outline shall not be smaller than the outline of the engagement face. ? Within18 millimetres, measured from the engagement face, the outline shall not be larger than outline of the the engagement face. insulation The outline of the engagement face can be adjusted as appropriate earthing pin current-carrying pin R = 1 max. engagement - 5 - ? Insulation sleeves on the current-carrying pins are mandatory. If the insulating sleeves are separate parts, they shall enter the plug 3 mm measured from the engagement face. ? The external diameter of the insulating sleeves shall not be larger than the diameter of the unisulated part of the pins. ? To avoid damage to the shutters, the end of the pins shall be smoothly rounds. ? The angle of 90 represents the maximum permissible angle for the orientation of the cable entry of the axis of the plug. ? The edge of the uninsulated part of the pins shall be smoothly rounds. The distance between the unisulated part of the pin and the insulated sleeves may not more than 0.2 mm.
