scope:

This part of IEC 60730 applies to the evaluation of thermal protectors for ballasts for tubular fluorescent lamps. This standard applies to thermal protectors using NTC or PTC thermistors, additional requirements for which are contained in Annex J. Requirements concerning the testing of the combination of ballasts and thermal protectors are given in IEC 61347-1. This standard applies to the inherent safety, to the operating values, operating times, and operating sequences where such are associated with equipment safety, and to the testing of thermal protectors used to protect ballasts for tubular lamps from overheating. This standard applies to thermal protectors for ballasts within the scope of IEC 61347-2-8. Thermal protectors covered by this standard may be suitable for ballasts for other discharge lamps such as ballasts under the scope of IEC 61347-2-9.
