1 Scope and normative references

This clause of Part 1 is applicable except as follows:

1.1 Replacement:

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 ballast and thermal protector are given in IEC 61347-1.

Add "and UL 935 or UL 8750." 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 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.

Throughout this standard the word "protector" means "self-resetting

thermal ballast protector

."

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 Replacement:

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 Replacement:

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 applies.

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.
