规定了听力计的一般要求和纯音听力计的特殊要求，纯音听力计设计用于通过心理声学测试方法测定听阈水平，并与标准参考听阈水平进行比较。本标准是对IEC 60645-1:2001的修改采用，并根据IEC 60645-1:2001进行了复制。

Specifies general requirements for audiometers and particular requirements for pure-tone audiometers designed for use in determining hearing threshold levels, in comparison with standard reference threshold levels by means of psychoacoustic test methods. This Standard is a modified adoption of, and has been reproduced from, IEC 60645-1:2001.
