IEC/EN 61643-11:2011
Low-voltage surge protective devices–Part11: Surge protective devices connected to low-voltage power systems–Requirements and test methods
IEC 61643-11:2011 is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are packaged to be connected to 50/60 Hz a.c. power circuits, and equipment rated up to 1 000 V r.m.s. Performance characteristics, standard methods for testing and ratings are established. These devices contain at least one nonlinear component and are intended to limit surge voltages and divert surge currents. This first edition of IEC 61643-11 cancels and replaces the second edition of IEC 61643-1 published in 2005. The main changes with respect of the second edition of IEC 61643-1 are the complete restructuring and improvement of the test procedures and test sequences.

IEC 61643-12:2020
Low-voltage surge protective devices - Part 12: Surge protective devices connected to low-voltage power systems - Selection and application principles
IEC 61643-12:2020 describes the principles for the selection, operation, location and coordination of SPDs to be connected to 50/60 Hz AC power circuits, and equipment rated up to 1 000 V RMS. These devices contain at least one non-linear component and are intended to limit surge voltages and divert surge currents.
NOTE 1 Additional requirements for special applications are also applicable, If required.
NOTE 2 IEC 60364 and IEC 62305-4 are also applicable.
NOTE 3 This standard deal only with SPDs and not with surge protection components
IEC 61643-22:2015
Low-voltage surge protective devices - Part 22: Surge protective devices connected to telecommunications and signalling networks - Selection and application principles
IEC 61643-22:2015 describes the principles for the selection, operation, location and coordination of SPDs connected to telecommunication and signalling networks with nominal system voltages up to 1 000 V r.m.s. a.c. and 1 500 V d.c. This standard also addresses SPDs that incorporate protection for signalling lines and power lines in the same enclosure (so called multiservice SPDs). This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Update the use of multiservice SPDs (Article 8);
- Comparison between SPD classification of IEC 61643-11 and IEC 61643-21 (7.3.3);
- Consideration of new transmission systems as PoE (Annex F);
- EMC requirements of SPDs (Annex G);
- Maintenance cycles of SPDs (Annex I). Keywords: SPD, surge protective devices
IEC 61643-31:2018
Low-voltage surge protective devices - Part 31: Requirements and test methods for SPDs for photovoltaic installations
https://343lzp26ts7kiqip8biqf71a-wpengine.netdna-ssl.com/wp-content/uploads/BS-EN-61643-31-2019-Low-voltage-surge-protective-devices-Part-31-Requirements-and-test-methods-for-SPDs-for-photovoltaic-installations.pdf
IEC 61643-31:2018 is applicable to Surge Protective Devices (SPDs), intended for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are designed to be connected to the DC side of photovoltaic installations rated up to 1 500 V DC. These devices contain at least one non-linear component and are intended to limit surge voltages and divert surge currents. Performance characteristics, safety requirements, standard methods for testing and ratings are established. SPDs complying with this standard are exclusively dedicated to be installed on the DC side of photovoltaic generators and the DC side of inverters. SPDs for PV systems with energy storage (e.g. batteries, capacitor banks) are not covered. SPDs with separate input and output terminals that contain specific series impedance between these terminal(s) (so called two-port SPDs according to IEC 61643-11:2011) are not covered. SPDs compliant with this standard are designed to be permanently connected where connection and disconnection of fixed SPDs can only be done using a tool. This standard does not apply to portable SPDs.
IEC 61643-32:2017
Low-voltage surge protective devices - Part 32: Surge protective devices connected to the d.c. side of photovoltaic installations - Selection and application principles
IEC 61643-32:2017 describes the principles for selection, installation and coordination of SPDs intended for use in Photovoltaic (PV) systems up to 1 500 V DC and for the AC side of the PV system rated up to 1 000 V rms 50/60 Hz. The photovoltaic installation extends from a PV array or a set of interconnected PV-modules to include the associated cabling and protective devices and the inverter up to the connection point in the distribution board or the utility supply point. This part of IEC 61643 considers SPDs used in different locations and in different kinds of PV systems:PV systems located on the top of a building. PV systems located on the ground like free field power plants characterized by multiple earthing and a meshed earthing system. The term PV installation is used to refer to both kinds of PV systems. The term PV power plant is only used for extended free-field multi-earthed power systems located on the ground. For PV installations including batteries additional requirements may be necessary.
IEC 62561-1:2017 RLV
Redline version
Lightning protection system components (LPSC) - Part 1: Requirements for connection components
IEC 62561-1:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 62561-1:2017 specifies the requirements and tests for metallic connection components that form part of a lightning protection system (LPS). Typically, these can be connectors, clamps, bonding and bridging components, expansion pieces and test joints.
For the purposes of this document the following connection types are considered as connection components: exothermic, brazing, welding, clamping, crimping, seaming, screwing or bolting. Testing of components for an explosive atmosphere is not covered by this document.
This second edition cancels and replaces the first edition, published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a. classification of connection components in permanent and non-permanent connection;
b. requirements and corresponding tests for permanent connection components such as exothermic, brazing, welding, crimping, seaming;
c. flow chart of tests for connection components.
