家用和类似用途的自动电气控制装置；第2部分:管状荧光灯镇流器热保护器的特殊要求SUL 60730-2-31范围第1部分的本条款适用，但以下情况除外:1.1更换:IEC 60730的本部分适用于管状荧光灯镇流器热保护器的评估。本标准适用于使用NTC或PTC热敏电阻的热保护器，其附加要求包含在附录J中。有关镇流器和热保护器组合测试的要求见IEC 61347-1.1.1DV第2部分第三段的修改:添加“和UL 935”直到句子的结尾。1.1.1本标准适用于固有安全、与设备安全相关的操作值、操作时间和操作顺序，以及用于保护管形灯镇流器不过热的热保护器的测试。 本标准适用于IEC 61347-2-8范围内镇流器的热保护器。本标准涵盖的热保护器可能适用于其他放电灯的镇流器，如IEC 61347-2-9范围内的镇流器。在本标准中，“保护器”一词是指“自复位热镇流器保护器”1.1.1DV对第2部分第2段的修改:添加“和UL 935”直到句子的结尾。1.1.2本标准不适用于用于保护镇流器的其他方式。1.1.3本标准不适用于打开电路的手动装置。1.2更换:本标准适用于与镇流器一起使用的保护器，用于在50 Hz或60 Hz下高达690 V的交流电源。1.3更换:如果响应值取决于在设备中安装控件的方法，则本标准不考虑控件自动动作的响应值。 如果响应值对保护用户或周围环境具有重要意义，则适用适当家用设备标准中定义的值或制造商确定的值。 1.101DV在第2部分中增加以下内容:在IEC术语中，“安全”定义为可接受的风险水平。这符合UL要求的意图，即降低火灾、电击或人身伤害的风险。

Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Thermal Protectors for Ballasts for Tubular Fluorescent LampsUL 60730-2-31 ScopeThis 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 61347-1.1.1DV Modification to the third 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 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."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 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. 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.
