This clause of Part 1 is replaced by the following:
This document applies to thermal protectors
• That are integrated or incorporated in ballasts for tubular fluorescent lamps;
• for use in ballasts of tubular fluorescent lamps used by the public , such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial
applications;
• that are AC or DC controls with a rated voltage not exceeding 690 V AC or 600 V DC
• using NTC or PTC thermistors and to discrete thermistors, requirements for which are contained in Annex J
• that are electromechanical or electronic in design and responsive to or controlling such characteristics as temperature.”.
NOTE 1 Throughout this document, the word "equipment" means "ballasts for tubular fluorescent lamps" and
“Controls” means “thermal protectors
NOTE 2 Requirements concerning the testing of the combination of ballasts and thermal protectors are given in
IEC 61347-.
This document applies to
– the inherent safety of thermal protectors for ballasts for tubular fluorescent lamps, and
– functional safety of thermal protectors used to protect ballasts for tubular fluorescent lamps from overheating,
– controls where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system,
– the operating values, operating times, and operating sequences where such are associated with equipment safety.
– Thermal protectors for ballasts within the scope of IEC 61347-2-8
– Thermal protectors that may be suitable for ballasts for other discharge lamps such as ballasts under the scope of IEC 61347-2-9
– This document does not apply to
• A manual device for opening the circuit
• Other means used to protect ballasts
