IEC 62561-5:2017 pdf download.Lightning protection system components (LPSC) – Part 5: Requirements for earth electrode inspection housings and earth electrode seals
1 Scope
This part of IEC 62561 specifies the requirements and tests for earth electrode inspection housings (earth housing) installed in the earth and for earth electrode seals. Lightning protection system components (LPSC) can also be suitable for use in hazardous atmospheres. There are therefore additional requirements when installing the components under such conditions. NOTE Different requirements and test procedures are given in EN 1 24 (all parts) and EN 1 253 (all parts).

5 Requirements
5.1 General All earth electrode inspection housings and earth electrode seals shall be so designed and constructed that in normal use their performance is reliable and without danger to persons and the surroundings. The choice of a material depends on its ability to match the particular application requirements. 5.2 Installation instructions The manufacturer or supplier of the earth electrode inspection housing and earth electrode seals shall provide adequate information in his literature to ensure that the installer can select and install the materials in a suitable and safe manner, in accordance with IEC 62305-3. Compliance is checked by review as per 6.4. 5.3 Earth electrode inspection housing The design of the earth electrode inspection housing shall be such that it carries out its function of enclosing the down conductor/earth rod termination in an acceptable and safe manner, and has sufficient internal dimensions to permit the assembly/disassembly of the earth rod clamp. The housing body shall be deep enough to permit the lid to sit flush on the body without fouling on the rod/conductor/clamp assembly. The material of the earth electrode inspection housing shall be compatible with its surrounding environment and shall comply with the tests given in 6.2. 5.4 Earth electrode seal The design of the earth electrode seal shall be such that, in an acceptable and safe manner, it carries out its function of preventing ground water bypassing the earth electrode and entering the foundation or wall of a building. The material of the earth electrode seal shall be compatible with its surrounding environment and comply with the tests given in 6.3.
