    1 Scope

    This clause of Part 1 is replaced as follows:

    1.1 This standard applies to the evaluation of thermal protectors for ballasts for tubular fluorescent lamps.

    Requirements concerning the testing of the combination of ballast and thermal protector are given in IEC 920.

    This part applies to thermal protectors using NTC or PTC thermistors, additional requirements for which are contained in Annex J.

    1.1DV Modification to the second paragraph of the part 2:

    Add "and UL 935." to the end of the sentence.

    1.1.1 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 920.

    Thermal protectors covered by this standard may be suitable for ballasts for other discharge lamps.

    Throughout this standard the word "protector" means "self-resetting thermal ballast protector."

    1.1.1DV Modification to the second paragraph of the part 2:

    Add "and UL 935." to the end of the sentence.

    1.1.2 This standard is not applicable to other means used to protect ballasts.

    1.1.3 This standard does not apply to a manual device for opening the circuit.

    1.2 This standard applies to protectors for use with ballasts for use on a.c. supplies up to 690 V at 50 Hz or 60 Hz.

    1.3 This standard does not take into account the response value of an automatic action of a control, if such a response value is dependent upon the method of mounting the control in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer shall apply.

    1.101DV Addition of the following to the part 2:

    In IEC terminology, "safety" is defined as an acceptable level of risk. This is consistent with the intentions of UL requirements to reduce the risk of fire, shock, or injury to persons.
