IEC 60645-7:2009适用于用于测量内耳、听神经和脑干的听觉诱发电位的仪器，这些诱发电位由短时间的声音和/或振动刺激诱发。IEC 60645-7:2009定义了制造商规定的特性，规定了筛查和诊断两种仪器的性能要求，并规定了这些仪器上应提供的功能。IEC 60645-7:2009的目的是确保使用符合本标准的不同仪器在可比试验条件下进行的测量结果保持一致。IEC 60645-7:2009无意限制新功能的开发或加入，也无意阻止创新方法。特殊用途电刺激的应用超出本标准的范围。

IEC 60645-7:2009 applies to instruments designed for the measurement of auditory evoked potentials from the inner ear, the auditory nerve and the brainstem, evoked by acoustic and/or vibratory stimuli of short duration. IEC 60645-7:2009 defines the characteristics to be specified by the manufacturer, specifies performance requirements for two types of instrument, screening and diagnostic, and specifies the functions to be provided on these types. The purpose of IEC 60645-7:2009 is to ensure that measurements made under comparable test conditions with different instruments complying with this standard will be consistent. IEC 60645-7:2009 is not intended to restrict development or incorporation of new features, nor to discourage innovative approaches. The application of electric stimuli for special purposes is beyond the scope of this standard.
