IEC 61019-2:20 05为电信、无线电设备和消费品中使用的声表面波（SAW）谐振器提供了实用指南。它将与IEC 61019-1结合使用。声表面波谐振器的特点是体积小、重量轻、免调节、稳定性高，工作频率延伸到VHF和UHF范围。与上一版本相比的主要变化如下: -在5.1的末尾，添加了边缘反射器。其参考文献已插入参考书目； -在表1中，添加了LiNbO3(64°Y)的传播特性； -在表3中，已更正条款和子条款编号，以便与取代IEC 61019-1-1(1990)和IEC 61019-1-2(1993)的IEC 61019-1(2004)一致。

IEC 61019-2:2005 gives practical guidance to the use of surface acoustic wave (SAW) resonators which are used in telecommunications, radio equipments and consumer products. It is to be used in conjunction with IEC 61019-1. The features of SAW resonators are small size, light weight, adjustment-free and high stability,operating frequencies extend to the VHF and UHF ranges. The main changes with respect to the previous editon are listed below:
- at the end of 5.1, the edge reflector has been added. Its reference literature has been inserted in the bibliography;
- in Table 1, the propagation properties of LiNbO3 (64° Y) have been added;
- in Table 3, the clause and subclause numbers have been corrected in order to be consistent with IEC 61019-1 (2004) which has replaced IEC 61019-1-1 (1990) and IEC 61019-1-2 (1993).
