ISO/IEC 30129:2015（E）规定了建筑和其他结构中各种导电元件之间的连接（连接）设计和安装的要求和建议，在其施工或翻新期间，信息技术（IT）和更一般地，电信设备的安装旨在a）最大限度地降低该设备的正确功能和互连电缆免受电气危害的风险，以及b）为电信设备提供可靠的信号参考，从而提高电磁干扰（EMI）的抗扰度。

ISO/IEC 30129:2015(E) specifies requirements and recommendations for the design and installation of connections (bonds) between various electrically conductive elements in buildings and other structures, during their construction or refurbishment, in which information technology (IT) and, more generally, telecommunications equipment is intended to be installed in order to a) minimise the risk to the correct function of that equipment and interconnecting cabling from electrical hazards and b) provide the telecommunications installation with a reliable signal reference - which may improve immunity from electromagnetic interference (EMI).
