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 socketoutlets 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.
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.
