IEC 61435:2013(E)适用于用于伽马射线和X射线辐射探测器的高纯度锗晶体。这种锗是单晶的，并且具有小于1011个电活性杂质中心/cm3的净浓度。本国际标准规定了高纯锗晶体基本特性测量的术语和测试方法。IEC 60973和IEC 60759中给出了完整组装的锗探测器的测试方法。与上一版相比，主要技术变化如下: -审查现有要求； -更新术语和定义。

IEC 61435:2013(E) is applicable to high-purity germanium crystals used for radiation detectors for gamma-rays and X-rays. Such germanium is monocrystalline and has a net concentration of fewer than 10¹¹ electrically active impurity centers per cm³. This International Standard specifies terminology and test methods for measurements of basic characteristics of high-purity germanium crystals. Test methods for completed assembled germanium detectors are given in IEC 60973 and IEC 60759. The main technical changes with regard to the previous edition are as follows:
- review the existing requirements;
- update the terminology and definitions.
