Lighting and Similar Equipment:  Radio Disturbance Limits (43 pages, available in Thai)
6. Description of content:   The Thai Industrial Standards Institute (TISI) has proposed to
enforce TIS 1956-2542 (1999) as a mandatory standard.  The standard covers limits for
radio frequency disturbances from:
- all lighting equipment with a primary function of generating and/or
distributing light intended for illumination purposes, and intended either for
connection to the low voltage electricity supply or for battery operation;
- the lighting part of multi-function equipment where one of the primary
functions of this is illumination;
- independent auxiliaries exclusively for use with lighting equipment;
- UV and IR radiation equipment;
- neon advertising signs;
- street/flood lighting intended for outdoor use;
- transport lighting (installed in buses and trains).
Excluded from the scope of this standard are:
- lighting equipment for aircraft and airports;
- apparatus for which the electromagnetic compatibility requirements in the
radio-frequency range are explicitly formulated in other IEC or CISPR
standards.G/TBT/Notif.00/510
Page 2
Note – Examples are:
- built-in lighting devices in other equipment, for example scale illumination
or neon devices;
- photocopiers;
- slide projectors;- lighting equipment for road vehicles.
Multi-function equipment which is subjected simultaneously to different clauses of this
standard and/or other standards shall meet the provisions of each clause/standard with the
relevant functions in operation.
The limits in this standard have been determined on a probabilistic to keep the suppression
of disturbances within economically reasonable limits while still achieving an adequate
level of radio protection and electromagnetic compatibility.  In exceptional cases additionalprovisions may be required.
7. Objective and rationale, including the na ture of urgent problems where applicable:
To prevent the damage that may inflict upon the persons and economies.
8. Relevant documents:   Publication in which the Notification is published when adopted:
