IEC 62561-1 Lightning Protection System Components (LPSC) - Part 1: Requirements for Connecting Components

EUROLAB laboratory provides testing and compliance services within the scope of IEC 62561-1 standard. This part of the IEC 62561 standard specifies the requirements and tests for metallic connection components that form part of a lightning protection system (LPS). Typically these can be connectors, clamps, clamping and bridging components, expansion pieces, and test connections.

IEC 62561-1 Lightning Protection System Components (LPSC) - Part 1: Requirements for Connecting Components

For the purposes of this standard, the following types of connections are considered connection components: exothermic, soldering, welding, clamping, crimping, sewing, screwing or bolting. Testing of components for explosive atmosphere is not covered by this document.

This section of IEC 62561 deals with the requirements and tests for lightning protection system components (LPSC) used for the installation of a lightning protection system (LPS) designed and implemented according to the IEC 62305 series.

Connecting components shall be designed so that their performance, when installed in accordance with the manufacturer's instructions, is reliable, robust and safe for persons and surrounding equipment. Compliance is checked by inspection. The manufacturer of the connecting components must provide at least the following information:

  • Classification of the component;
  • Recommended tightening torque;
  • Conductor sizes and material range;
  • Connection configuration.

Unless otherwise specified, tests are performed with specimens assembled and installed as in normal use according to the manufacturer's or supplier's installation instructions with recommended conductor materials, dimensions and tightening torques. If the connector is suitable for materials of various conductors, it will be tested on each material combination.

All tests are performed on new samples. Unless otherwise stated, three samples are tested and the requirements are met if all tests are met.

If, due to an assembly or manufacturing defect, only one of the samples does not meet a test, this test and any previous tests that may have affected the results of the test should be repeated, and further tests should be performed on another complete set of samples, all of which will comply with the requirements.

When submitting sample sets, the applicant may also submit an additional set of samples, which may be required in the event of a sample failure. The test station will then test the additional set of samples without any request and reject it only if another failure occurs. Failure of a sample will result in rejection if the additional sample set is not submitted at the same time.
