电绝缘材料.测定电离辐射对绝缘材料的效应.第2部分:辐照和试验规程

[中文适用范围]： IEC 60544 的本部分规定了在确定辐射引起的物理或化学性质变化之前，在用电离辐射照射绝缘材料期间和之后对暴露条件保持的控制。该标准规定了许多潜在重要的辐照条件以及可能影响这些条件下辐射诱发反应的各种参数。该标准的目的是强调选择合适的样品@暴露条件和测试方法的重要性，以确定辐射对适当选择的性能的影响。由于许多材料在空气或惰性环境中使用，建议针对这两种情况使用标准暴露条件。应当指出的是，本标准不考虑在辐照期间进行的测量。 [外文原描述]： IEC 60544-2:2012 specifies the controls maintained over the exposure conditions during and after the irradiation of insulating materials with ionizing radiation prior to the determination of radiation-induced changes in physical or chemical properties. This standard specifies a number of potentially significant irradiation conditions as well as various parameters which can influence the radiation-induced reactions under these conditions. The objective of this standard is to emphasize the importance of selecting suitable specimens, exposure conditions and test methods for determining the effect of radiation on appropriately chosen properties. Since many materials are used either in air or in inert environments, standard exposure conditions are recommended for both of these situations. It should be noted that this standard does not consider measurements which are performed during the irradiation. This edition includes the following significant technical changes with respect to the previous edition: - alignment with standards recently developed by SC 45A as well as with other parts in the IEC 60544 series.
