5. Title, number of pages and language(s) of the notified document: Draft Thai 
Industrial Standard for Ballasts for Tubular Fluorescent Lamps: Safety Requirements (58 pages, in Thai) 
6. Description of content: The Thai Industrial Standards Institute (TISI) has proposed to 
withdraw TIS 23-2521 (1978) ballasts for fluorescent lamps, and replace it with TIS 23-25XX as a mandatory standard. This standard deals with the safety requirements 
for ballasts, excluding resistance types, for us e on a.c. supplies up to 1,000 V at 50 Hz or 
60 Hz, associated with fluorescent lamps with or without pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and 
characteristics as specified in TIS 236 and TIS 1713. This standard applies to complete 
ballasts and to their component parts such as reactors, transformers and capacitors. Particular requirements for thermally protected ballasts are given in annex B.  
Ballasts for conventional operation of lamps at mains frequency are covered, while a.c. 
supplied electronic ballasts for high frequency operation are excluded. These are specified in TIS 885. Capacitors having a capacitance greater than 0,1 µF comply with TIS 191or other relevant standards. Capacitors having a capacitance less than or equal to 0,1 µF 
comply with relevant standards. 
7. Objective and rationale, including the nature of urgent problems where
