The Thai Industrial Standards Institute (TISI) released two safety standards for lamps:
TIS 2779-2562 “Double-capped LED lamps designed to retrofit linear fluorescent lamps - Safety specifications”
TIS 2780-2562 “Self-ballasted LED-lamps for general lighting services by voltage >50 V - Safety specifications”
TIS 2779-2562 is identical to IEC 62776:2014+Cor1:2015 and applies to double-capped LED lamps with G5 and G13 caps, intended to replace fluorescent lamps with the same caps:
Rated power up to 125 W
Rated voltage up to 250 V
TIS 2780-2562 is harmonized with IEC 62560:2011+AMD1:2015 and applies to self-ballasted LED-lamps, intended for domestic and similar general lighting purposes:
Rated wattage up to 60 W
Rated voltage of > 50 V up to 250 V
Both standards specify general safety and testing requirements as well as specific requirements:
Pin-safety during insertion
Protection against accidental contact with live parts
Mechanical requirements for caps
Resistance to heat, flame and ignition
Fault conditions, etc.
Provisions of these standards become mandatory from March 29, 2022.
